It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, an interference display method for positioning navigation is provided, and the embodiment is applied to an electronic device for illustration by the method. The electronic device may be a terminal or a server. The method can also be applied to a system comprising a terminal and a server, and is realized through interaction of the terminal and the server.

The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The server may be implemented as a stand-alone server or as a server cluster composed of a plurality of servers.
As shown in fig. 1, the method comprises the steps of:
step 102, in the navigation process of the electronic device, interference detection is performed on the current environment to obtain interference state parameters.
The interference state parameter refers to a state parameter of an interference signal detected by the electronic device. The interference state parameter includes at least one of an interference strength, an interference direction, and an interference source type.
The interference intensity refers to the intensity of an interference signal detected by the electronic device. The stronger the interference strength, the greater the interference of the interference signal to the electronic device, and the electronic device may not accurately realize navigation. The interference direction is the direction of the interference source of the interference signal. The type of the interferer is the type to which the interferer of the interferer belongs. The types of interference sources may include natural interference sources and artificial interference sources.
The electronic device may employ GNSS (Global Navigation Satellite System ) for navigation, and in the process of GNSS navigation, GNSS interference detection is performed on the current environment. The GNSS includes GPS (Global Positioning System ), GLONASS (GLOBAL NAVIGATION SATELLITE SYSTEM, gnonass), GALILEO (Galileo satellite navigation system ), or beidou satellite navigation system, among others.
The interference intensity is 0 or more. If an interference signal exists in the current environment, the obtained interference intensity is larger than 0; if no interference signal exists in the current environment, the obtained interference intensity is equal to 0.
Specifically, the electronic equipment responds to the starting operation of navigation software, displays a navigation page and enters a navigation process, acquires an input starting position and a target position in the navigation page, plans a navigation path from the starting position to the target position, and navigates according to the navigation path; in the navigation process, interference detection is carried out on the current environment so as to determine the interference state parameters of the interference signals detected in the current environment.
Step 104, determining the interference identification corresponding to the interference state parameter, and displaying the interference identification.
The interference identification is an identification characterizing an interference signal state parameter in the current environment of the electronic device. The form of the interference mark is not limited, and may specifically be a pattern mark, a text mark, a color mark, or the like.
And the electronic equipment determines the interference identification corresponding to the interference state parameter from the corresponding relation between the preset interference state parameter and the interference identification, and displays the interference identification in a screen of the electronic equipment through a display module.

Alternatively, the electronic device may display at least one of the interference intensity, the interference direction, and the interference value.
In this embodiment, during the navigation process of the electronic device, interference detection is performed on the current environment, so that an interference state parameter can be obtained, and thus an interference identifier corresponding to the interference state parameter is determined and displayed. The interference identifier displayed in the electronic equipment can accurately display the interference condition in the current environment, so that corresponding processing is carried out on the interference condition, and more accurate navigation is realized.
In one embodiment, the interference state parameter is interference strength; determining an interference identifier corresponding to the interference state parameter comprises the following steps: if the interference intensity is interference-free, determining that an interference mark corresponding to the interference intensity is interference-free mark; if the interference intensity is interference, determining that the interference mark corresponding to the interference intensity is the interference mark.
And if the interference intensities are interference-free, which means that no interference signal exists in the current environment of the electronic equipment, determining that the interference mark corresponding to the interference intensity is the interference-free mark. As shown in fig. 2, is a clear identification.
If the interference intensity is interference, which means that an interference signal exists in the current environment of the electronic equipment, the interference mark corresponding to the interference intensity is determined to be the interference mark. As shown in fig. 3, with interference identification, very strong interference is indicated.
Further, if the interference intensities are interference, determining that the interference identifier corresponding to the interference intensity is the interference identifier, including: if the interference intensity is the first-level interference, determining an interference identifier corresponding to the interference intensity as a first interference identifier; if the interference intensity is the second-level interference, determining an interference identifier corresponding to the interference intensity as a second interference identifier; if the interference intensity is three-level interference, determining an interference mark corresponding to the interference intensity as a third interference mark; the interference intensities of the primary interference, the secondary interference and the tertiary interference are sequentially increased.
The interference intensity of the first-level interference, the second-level interference and the third-level interference are sequentially increased, namely, the interference intensity of the first-level interference is minimum, the interference intensity of the second-level interference is medium, and the interference intensity of the third-level interference is maximum.
In other embodiments, the electronic device may also set the interference strength to include level 2 interference, level 4 interference, level 5 interference, etc., the interference strength level not being limited in number.
In this embodiment, if the interference intensities are no interference, it is determined that the interference identifier corresponding to the interference intensity is a no-interference identifier; if the interference intensity is interference, determining that the interference mark corresponding to the interference intensity is the interference mark. Whether the interference signal exists in the current environment of the electronic equipment can be clearly distinguished, so that corresponding processing can be more accurately carried out, and more accurate navigation can be realized.
In one embodiment, displaying the interference identification includes: displaying an interference identifier at a target position of a screen; the target location is one of a top status bar, a bottom status bar, and a sidebar.

The electronic equipment detects whether the interference detection function is started or not in real time, if the interference detection function is not started, the interference display function is closed, the power consumption of the interference display function under the condition that the interference detection function is not started can be avoided, and the resources of the electronic equipment are saved.
In one embodiment, as shown in fig. 8, the electronic device detects whether to turn on the interference detection function in real time, and if not, turns off the interference display function, and does not display the identifier; if the interference detection function is started, the current environment is subjected to interference detection to obtain interference intensity, and an interference identifier corresponding to the interference intensity is determined. Wherein, the interference intensities are interference-free, and then display interference-free marks; if the interference strength is weak interference, displaying a weak interference mark; if the interference strength is strong interference, displaying a strong interference identifier; and if the interference intensities are extremely strong interference, displaying an extremely strong interference mark.

In one embodiment, as shown in fig. 10, performing interference detection on the current environment to obtain interference state parameters, including:
step 1002, obtaining target feature information of a target radio frequency parameter, where the target radio frequency parameter is generated when a signal processing circuit performs signal processing on a satellite positioning signal, and the target feature information is obtained by performing signal processing on a received target satellite positioning signal through the signal processing circuit.
Wherein the target radio frequency parameters include, but are not limited to, at least one of signal description parameters and hardware state parameters of the satellite positioning signals when decoded into navigation messages. Wherein the signal description parameter is used to represent the signal state of the satellite positioning signal. The hardware state parameter is used to represent the hardware state of the signal processing circuit. Optionally, the target radio frequency parameters include, but are not limited to, PGA (Programmable Gain Amplifier ) gain, IQ (In-phase Quadrature) SIGNAL level, sr (SIGNAL-NOISE RATIO), nf (NOISE level), CN0 (carrier-to-NOISE RATIO), NOISE floor, baseBand Amplitude (baseband amplitude), and the like, which are not limited In this embodiment. Among the above listed target rf parameters, signal interference of the satellite positioning signal may have an influence on the above listed target rf parameters, so that a specific interference result may be determined. The target satellite positioning signal is a satellite positioning signal received by the signal processing circuit, and can be understood as a satellite positioning signal to be detected as an interference result. The target characteristic information may be used to represent a change condition of the target radio frequency parameter, or may be used to represent a specific parameter value of the target radio frequency parameter, which is not limited in this embodiment. Because the target radio frequency parameter is generated when the signal processing circuit processes the satellite positioning signal, and the target characteristic information is used for representing the change condition of the target radio frequency parameter or representing the specific parameter value of the target radio frequency parameter, the target characteristic information can reflect the interference result of the target satellite positioning signal to a certain extent.
Specifically, when the signal processing circuit receives and processes the target satellite positioning signal, the signal processing circuit generates a target radio frequency parameter so as to obtain target characteristic information, and the electronic equipment obtains the target characteristic information obtained by processing the target satellite positioning signal by the signal processing circuit.
Step 1004, performing interference detection on the target satellite positioning signal according to the target feature information to obtain an interference result of the target satellite positioning signal, wherein the interference result comprises an interference state parameter.
Because the target characteristic information can reflect the interference result of the target satellite positioning signal to a certain extent, the electronic equipment can perform interference detection on the target satellite positioning signal according to the target characteristic information, so that the interference result of the target satellite positioning signal is obtained, and the interference result comprises interference state parameters.
According to the technical scheme, the interference detection is carried out on the target satellite positioning signals through the target characteristic information of the target radio frequency parameters generated when the signal processing circuit carries out signal processing on the target satellite positioning signals, so that the interference result of the target satellite positioning signals is obtained, the problem that the related technology cannot determine how to interfere the satellite positioning signals is solved, and the determination of the interference result of the satellite positioning signals is realized.
In one possible embodiment, obtaining target characteristic information of the target radio frequency parameter includes:
acquiring a plurality of parameter values corresponding to the target radio frequency parameters output by the signal processing circuit, and performing signal processing on the target satellite positioning signals by the plurality of parameter values through the signal processing circuit; at least one parameter value is selected from the plurality of parameter values as target feature information.
Wherein at least one parameter value is selected from the plurality of parameter values as the target feature information, i.e. the target feature information comprises one or more parameter values. The term "plurality" means two or more. If at least two parameter values are selected from the plurality of parameter values as the target feature information, the continuous at least two parameter values may be used as the target feature information.
It should be noted that the target satellite positioning signal may be a continuously received satellite positioning signal, and the signal processing circuit processes the satellite positioning signal once to obtain a parameter value, and the signal processing circuit processes the continuously received satellite positioning signal to obtain a plurality of parameter values.
In this embodiment, the number of parameter values included in the target feature information may be related to the desired interference result. Wherein the interference result may be used to represent, but is not limited to, at least one of: the present embodiment is not limited, whether signal interference occurs to the target satellite positioning signal, the time when signal interference occurs, whether interference disappears, the time when interference disappears, the interference direction, the type of the interference source, the frequency band of interference, the interference intensity, and the like.
In general, the interference of the target satellite positioning signal may be single tone noise interference or wideband noise interference. Single tone noise interference refers to interference in which the interfering signal has a distinct peak, which appears as a "personality" glitch. Specifically, the interference signal that generates the single noise interference may fall into a satellite constellation, may fall between two adjacent satellite constellations, may fall before the signal processing circuit, and may exist in at least two cases. Broadband noise interference means that there are no distinct peaks in the interference signal spectrum, which overall appears as a "personality" free spur. Specifically, the interference signal that generates wideband noise interference may fall into a satellite constellation, may fall between two adjacent satellite constellations, may fall before the signal processing circuit, and may exist in at least two cases.
The following embodiments further describe how to obtain the interference result of the target satellite positioning signal based on any of the above embodiments.
In one embodiment, as shown in fig. 11, the interference detection is performed on the target satellite positioning signal according to the target feature information, including steps 1102 to 1108.
Step 1102, determining the variation amplitude of the target radio frequency parameter according to the target characteristic information.
Wherein the amplitude of the change is used to represent the magnitude of the change in the target radio frequency parameter. In general, the larger the variation amplitude of the target radio frequency parameter is, the larger the variation of the target radio frequency parameter is; the smaller the amplitude of the change in the target radio frequency parameter, the smaller the change in the target radio frequency parameter.
In one possible embodiment, the target characteristic information includes at least two parameter values of the target radio frequency parameter, such that a magnitude of change of the target radio frequency parameter is determined from the at least two parameter values. In particular, the amplitude of the change may be a difference between adjacent ones of the at least two parameter values.
Step 1104, judging whether the variation amplitude is higher than a preset amplitude.
In this embodiment, if the variation is higher than the preset value, step 1106 is performed. Optionally, if the variation amplitude is not higher than the preset amplitude, the process returns to step 1102.
Step 1106, obtaining a target variation trend of the target radio frequency parameter, where the target variation trend is a variation trend of the target radio frequency parameter when the variation amplitude is higher than a preset amplitude.
In this embodiment, if the variation amplitude is higher than the preset amplitude, the target variation trend of the target radio frequency parameter is obtained. Alternatively, the target change trend may be increased or decreased, which is determined according to the actual situation when the interference is detected, which is not limited in this embodiment.
Step 1108, determining that the signal interference or the disappearance of the signal interference occurs to the target satellite positioning signal according to the target change trend.
In this embodiment, it may be that the target satellite positioning signal generates signal interference when the target change trend is that the target radio frequency parameter increases, and the target satellite positioning signal generates signal interference when the target change trend is that the target radio frequency parameter decreases and disappears; or the target change trend is that the target radio frequency parameter is reduced, the target satellite positioning signal generates signal interference, and the target change trend is that the target radio frequency parameter is increased, the target satellite positioning signal generates signal interference and disappears, and the embodiment is not limited in relation to the specific characteristics of the target radio frequency parameter.
According to the technical scheme, the target change trend of the target radio frequency parameter is obtained under the condition that the change amplitude is higher than the preset amplitude, so that signal interference or disappearance of signal interference of the target satellite positioning signal is determined according to the target change trend, the problem that the calculation power is high due to the fact that interference detection is always carried out through the target change trend is avoided, and the reduction of resources required for interference detection is realized.
In one possible implementation manner, the target satellite positioning signal is a high-frequency signal, the signal processing circuit includes a signal conversion module and a sampling module, the signal conversion module is used for converting the target satellite positioning signal into an intermediate frequency signal, the sampling module is used for sampling the intermediate frequency signal to obtain a sampling signal level, the target radio frequency parameter includes the sampling signal level, and determining that signal interference or signal interference disappearance occurs in the target satellite positioning signal according to a target change trend includes: if the target change trend is that the level of the sampling signal is increased, signal interference occurs to the target satellite positioning signal; if the target change trend is that the level of the sampling signal is reduced, the signal interference of the target satellite positioning signal disappears. The target satellite positioning signal generates signal interference, namely the interference strength is interference; and if the signal interference of the target satellite positioning signal disappears, the interference intensity is switched to be interference-free.
The target satellite positioning signal in the present embodiment is a carrier signal, and thus the target satellite positioning signal is a high frequency signal. The intermediate frequency signal may be an IQ signal. The IQ signal is an in-phase quadrature signal, I is in-phase, Q is quadrature, and the phase of the IQ signal is 90 degrees out of phase with that of I. The sampling module samples the IQ signal to obtain the sampling signal level corresponding to the IQ signal.
In this embodiment, if there is signal interference in the target satellite positioning signal, the sampled signal level will increase; if the signal interference of the target satellite positioning signal disappears, the sampled signal level will decrease, so that the situation that the signal interference of the target satellite positioning signal occurs or the situation that the signal interference disappears can be determined by the change trend of the sampled signal level.
In one possible implementation, the target radio frequency parameter includes a sampling gain of a sampling module, where the sampling gain is used to maintain a stability of a sampled signal level, and determining that the signal interference or the signal interference loss occurs in the target satellite positioning signal according to a target variation trend includes: if the target change trend is that the sampling gain is reduced, signal interference occurs to the target satellite positioning signal; if the target change trend is that the sampling gain is increased, the signal interference of the target satellite positioning signal disappears.
In this embodiment, if there is signal interference in the target satellite positioning signal, the sampled signal level will increase, and in order to keep the sampled signal level stable, the sampling gain will decrease; if the signal interference of the target satellite positioning signal disappears, the sampled signal level will decrease, and at this time, in order to keep the sampled signal level stable, the sampling gain will increase. Therefore, whether the signal interference occurs or the signal interference disappears can be determined by the variation trend of the sampling gain.
In one possible implementation, the target radio frequency parameters include a sampling signal level and a sampling gain. In this embodiment, if the target variation trend is that the sampling signal level increases and the sampling gain decreases, signal interference occurs in the target satellite positioning signal; if the target change trend is that the sampling signal level is reduced and the sampling gain is increased, the signal interference of the target satellite positioning signal disappears.
In one possible implementation, the target radio frequency parameters include a first target radio frequency parameter and a second target radio frequency parameter, the first target radio frequency parameter being related to the second target radio frequency parameter; performing interference detection on the target satellite positioning signal according to the target characteristic information to obtain an interference result of the target satellite positioning signal, including: and determining an interference result of the target satellite positioning signal according to the first target characteristic information and the second target characteristic information, wherein the first target characteristic information is the target characteristic information of the first target radio frequency parameter, and the second target characteristic information is the target characteristic information of the second target radio frequency parameter.
According to the technical scheme, the interference result of the target satellite positioning signal is determined through the target characteristic information corresponding to the target radio frequency parameters, so that the accuracy of interference detection is higher.
In one embodiment, as shown in fig. 12, determining the interference result of the target satellite positioning signal according to the first target feature information and the second target feature information includes steps 1202 to 1206.
Step 1202, determining a first variation condition of the first target radio frequency parameter according to the first target feature information.
The first change condition is determined according to the first target characteristic information, and the first target radio frequency parameter is changed. In this embodiment, the first target feature information includes a plurality of parameter values, and the first change condition may be determined according to a plurality of parameter values in succession in the first target feature information.
Step 1204, determining a second variation condition of the second target radio frequency parameter according to the second target characteristic information.
The second change condition is determined according to the second target characteristic information, and the second target radio frequency parameter is changed. In this embodiment, the second target feature information includes a plurality of parameter values, and the second variation condition may be determined according to a plurality of parameter values in succession in the first target feature information.
Step 1206, determining the interference strength of the signal interference generated by the target satellite positioning signal according to the first variation condition and the second variation condition.
In this embodiment, the first variation situation and the second variation situation are combined together to determine the interference strength of the signal interference generated by the target satellite positioning signal.
In one possible implementation manner, the target satellite positioning signal is a high-frequency signal, the signal processing circuit includes a signal conversion module and a sampling module, the signal conversion module is used for converting the target satellite positioning signal into an intermediate frequency signal, the sampling module is used for sampling the intermediate frequency signal to obtain a sampling signal level, the first target radio frequency parameter is the sampling signal level, the second target radio frequency parameter is a sampling gain of the sampling module, and the sampling gain is used for maintaining the stability of the sampling signal level.
Specifically, when positioning is performed according to a target satellite positioning signal, the signal conversion module in the signal processing circuit is generally required to convert the target satellite positioning signal from a high-frequency signal to an intermediate-frequency signal, and then the intermediate-frequency signal is sampled by the sampling module to obtain a sampling signal level, so that positioning is performed according to a sampling result. In the sampling process, in order to ensure the safety of the sampling module, the level of the C sampling signal can be kept stable by adjusting the sampling gain.
In this embodiment, the sampled signal level is used as the first target radio frequency parameter, and the sampled gain is used as the second target radio frequency parameter, so that the interference result of the target satellite positioning signal is determined according to the first variation condition of the sampled signal level and the second variation condition of the sampled gain.
It is to be understood that the first target rf parameter and the second target rf parameter in this embodiment may be other rf parameters, so long as the rf parameters are generated when the signal processing circuit processes the satellite positioning signal, and can reflect whether the satellite positioning signal has signal interference, which is not limited in this embodiment.
In the following embodiments, one of the sampled signal levels and one of the sampled gains are illustrated.
Referring to fig. 13, fig. 13 is a schematic diagram of IQ signal level and PGA gain versus satellite positioning signal when an interference signal is stabilized according to an embodiment of the present application. Wherein the IQ signal level is one of the sampled signal levels. PGA gain is one of the sampling gains. When an analog signal in a signal processing circuit is converted into a digital signal, the gain of the PGA is larger, and the IQ signal level is larger; the smaller the PGA gain, the smaller the IQ signal level. The PGA gain can dynamically adjust the IQ signal level to keep the IQ signal level within the effective range of the sampling module. In an ideal environment, the PGA gain and IQ signal level are stable and constant.
As shown in fig. 13, when the interference signal enters the circuit along with the target satellite positioning signal, the IQ signal level increases instantaneously, thereby triggering the PGA gain reduction, and after the gain reduction, the IQ signal level decreases. After the interference signal is removed, the IQ signal level is instantaneously reduced, thereby triggering the PGA gain to increase, and after the gain is increased, the IQ signal level is increased.
However, as the interference signal increases, the gain is continuously reduced in the gain adjustment range, and the IQ signal level fluctuates up and down but is limited in the preset signal interval. The interference signal continues to increase, the gain control range is exceeded, the PGA gain reaches the lower limit extreme value of the range, and the signal level can be raised. The interference signal continues to increase, and the IQ signal level eventually reaches the upper limit value of the preset signal interval.
The above is the basic principle of interference detection, of course, in practical situations, the radio frequency parameters are not only PGA gain and IQ signal level, but also signal-to-noise ratio, background noise level, etc., and the principle is similar, and will not be discussed here.
In one possible embodiment, the interference strength includes at least one of primary interference, secondary interference and tertiary interference, and determining the interference strength of the signal interference generated by the target satellite positioning signal according to the first variation condition and the second variation condition includes:
If the first change condition is that the signal fluctuation value of the sampling signal level in the preset signal interval is lower than the preset fluctuation value, and the second change condition is that the sampling gain continuously becomes smaller in the gain regulation range, the target satellite positioning signal generates primary interference;
if the first change condition is that the signal fluctuation value of the sampling signal level in the preset signal interval is higher than or equal to the preset fluctuation value, and the second change condition is that the sampling gain is continuously located at the range lower limit extremum of the gain regulation range, the target satellite positioning signal is subjected to secondary interference;
if the first variation condition is that the sampling signal level is continuously located at the upper limit extremum of the preset signal interval and the second variation condition is that the sampling gain is continuously located at the lower limit extremum of the gain regulation range, three-level interference occurs to the target satellite positioning signal.
In this embodiment, the correlation between the IQ signal level and the PGA gain and the satellite positioning signal is studied, so that the interference result of the target satellite positioning signal is determined according to the first variation of the IQ signal level and the second variation of the PGA gain.
According to the technical scheme of the embodiment, the interference result of the target satellite positioning signal is determined through the first change condition of the IQ signal level and the second change condition of the PGA gain, excessive operation is not needed, and resources needed for determining the interference result are reduced.
It can be understood that, in this embodiment, the interference result of the satellite positioning signal may also be determined by other radio frequency parameters, so long as the change of the relationship between the radio frequency parameter and the satellite positioning signal is studied, the specific radio frequency parameter for determining the interference result is not limited in this embodiment.
It should be noted that, in this embodiment, at least one kind of interference intensity detection may be selected according to needs, and the specific interference intensity to be detected is not limited in this embodiment.
In one embodiment, as shown in fig. 14, the interference detection is performed on the target satellite positioning signal according to the target feature information to obtain the interference result of the target satellite positioning signal, which includes steps 1002 to 1004.
Step 1402, obtaining a target mapping relationship, where the target mapping relationship represents a relationship between the feature information and the interference information.
Wherein the interference information includes at least one of an interference frequency and an interference strength. Specifically, if the plurality of disturbance information includes disturbance frequency, the target mapping relationship is a relationship between the feature information and the disturbance frequency. And if the plurality of disturbance information comprises disturbance intensity, the target mapping relation is the relation between the characteristic information and the disturbance intensity. The plurality of disturbance information comprises disturbance frequency and disturbance intensity, and the target mapping relation is the relation between the characteristic information and the disturbance frequency-disturbance intensity.
In one possible implementation, various interference signals (interference numbers 1-N) can be generated by using a measuring instrument (such as an instrument), the intensity of the interference signals is increased (or decreased) in steps, the full-band is traversed by the output of the same interval in the satellite frequency band, the full intensity (from weak to no reaction to strong to beyond the detection range) is recorded, the measurement data is recorded in the measuring process, and the mapping relation between the characteristic information and the interference information of the radio frequency parameters is formed and recorded in the detection database.
Step 1404, determining target interference information corresponding to the target feature information according to the target mapping relationship, where the target interference information is used as interference information of interference generated by the target satellite positioning signal, and the target interference information includes at least one of a target interference frequency and an interference intensity.
In this embodiment, since the target mapping relationship represents the relationship between the feature information and the interference information, the target interference information corresponding to the target feature information may be determined according to the target mapping relationship, so that the determined target interference information is used as the interference result of the target satellite positioning signal.
According to the technical scheme, the target interference information corresponding to the target characteristic information is determined through the target mapping relation, so that the determined target interference information is used as an interference result of the target satellite positioning signal, specific interference information can be accurately determined, for example, specific interference intensity and interference frequency can be accurately determined, and the accuracy of the obtained interference result is improved.
It should be noted that, if the single-tone noise needs to be detected, the target feature information may include a parameter value, so as to determine the interference information according to the parameter value; the target characteristic information may include a plurality of parameter values, and the interference information may be determined based on the average value by averaging the plurality of parameter values, or may be determined based on the median by selecting the median of the plurality of parameter values. If wideband noise needs to be detected, the target characteristic information may include a continuous plurality of parameter values, such that the interference information is determined from the continuous plurality of parameter values.
It should be understood that, although the steps in the flowcharts related to the embodiments described above are sequentially shown as indicated by arrows, these steps are not necessarily sequentially performed in the order indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders.
