Description
Technical Field

Background
The Global Navigation Satellite System (GNSS) is developed rapidly and widely used due to its all-weather, Global, real-time and high-precision features. The basic principle of GNSS is electromagnetic wave ranging, and when an electromagnetic wave signal crosses a neutral atmosphere, a signal propagation path is deviated due to the change of a vertical refractive index of a corresponding medium, and a path delay generated by the process is called tropospheric delay and mainly comprises dry delay and wet delay. As one of the most dominant errors in GNSS navigation and positioning, the effect on the tropospheric delay is not negligible. At present, the dry delay size in the tropospheric delay can be well estimated through a corresponding dry delay model, and the wet delay size also needs to be solved as a parameter to be estimated.
However, at present, the solution of the magnitude of the wet delay is usually to project the tropospheric wet delay of the electromagnetic wave propagation path between all satellites received by the survey station to the zenith direction by using a mapping function to estimate, that is, the zenith wet delay between each survey station and the satellite is obtained first, and then the zenith wet delay is used as the total wet delay of the tropospheric layer.
Based on this, in the case where the wet delay data includes only the zenith wet delay, that is, the wet delay in the zenith direction, the distribution information of the tropospheric wet delay in the three-dimensional direction cannot be reflected at all.

However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the present invention relates to a method of generating a wet latency data text. In practical application, the method may be applied to any terminal device capable of processing information of electromagnetic wave propagation paths between an observation station and all received satellites to obtain troposphere diagonal path delay data, that is, the device may be a server device or a client device, which is not limited in this embodiment.
The following describes implementation details of the method for generating the wet delay data text of the present embodiment, and the following is provided only for easy understanding and is not necessary for implementing the present embodiment.
The specific flow of this embodiment is shown in fig. 1, and specifically includes the following steps:
Specifically, in this embodiment, the pre-agreed wet delay parameters related to wet delay at least include an "observation station-satellite number parameter", an "observation station latitude parameter", an "observation station longitude parameter", an "observation station geodetic altitude parameter", a "navigation satellite system type parameter", an "inclined path wet delay parameter", a "satellite altitude angle parameter", and a "satellite azimuth angle parameter".
Regarding the "observation Station-Satellite number parameter", in practical applications, it can be represented by "Station-Satellite", specifically which is the current observation Station, and the observed Satellite is a Satellite of several numbers, such as "GXNG-2", where "GXNG" is the observation Station that actually performs observation, and "2" is the Satellite number 2 observed by the observation Station.
Regarding the "observation station latitude parameter", in practical applications, the "LAT" may be used to represent the latitude of the observation station, for example, "N32.5" represents the latitude of the observation station as north latitude 32.5 degrees.
Regarding the "longitude parameter of the observation station", in practical applications, the "LON" may be used to represent, specifically, the longitude of the observation station, for example, "E120.8" represents that the longitude of the observation station is 120.8 degrees from east longitude.
Regarding the "survey station geodetic HEIGHT parameter", in practical applications, it may be represented by "HEIGHT", specifically, the geodetic HEIGHT of the survey station, for example, "850.8M" represents that the geodetic HEIGHT of the survey station is 850.8 meters.
Regarding the "Navigation Satellite system type parameter", in practical applications, it may be represented by "NAVSTAR", specifically representing the type of Satellite observed by the observation station, such as "G", representing the global positioning system gps (global Position system) in the united states, further such as "R", representing the GLONASS global Satellite Navigation system GLONASS in russia, further such as "C", representing the beidou Navigation Satellite Navigation system bsd (beidou Navigation Satellite system) in china, and further such as "E", representing the Galileo positioning system Galileo in europe.
Regarding the "inclined path wet delay parameter", in practical applications, it may be represented by "SWD", that is, a slant wet delay, specifically representing an inclined path wet delay amount between the observation station and the observed satellite, for example, "201.70" represents that the inclined path wet delay amount between the observation station and the observed satellite is 201.70.
Regarding the "satellite Elevation angle parameter", in practical applications, it can be represented by "Elevation", specifically, the Elevation angle of the observed satellite relative to the observation station, for example, "47.19" represents that the Elevation angle of the observed satellite relative to the observation station is 47.19 degrees.
Regarding the "satellite Azimuth parameter", in practical applications, it may be represented by "Azimuth", specifically, the Azimuth of the observed satellite relative to the observation station, for example, "5" represents that the Azimuth of the observed satellite relative to the observation station is 5 degrees.
In addition, in practical applications, the preset wet delay parameter may include any number of customized parameters in addition to the 8 parameters.
For convenience of illustration, the present embodiment uses the custom parameter as the total delay of the ramp path, i.e. stw (slant total delay).
It will be appreciated that the STW in this embodiment includes both dry and wet delays.
Due to the wet delay and the acquisition of the content corresponding to the SWD parameters, in practical application, the dry delay data between the observation station and the satellite to be measured can be determined according to the known SWD and STW.
Therefore, by setting the wet delay parameters and the STW parameters, in the subsequent use process, a user can extract the dry delay data according to the data recorded in the STW in the current wet delay data text, and then directly use the dry delay data, namely, a dry delay model does not need to be specially constructed, and then the observation data provided by the observation station is processed to obtain the dry delay data.
In addition, the blank document of the mood in the embodiment may be a document in a format such as a notepad, a tablet, a word, an Excel, and the like, which is not listed here, and the embodiment is not limited thereto.
In addition, it is worth mentioning that, in order to facilitate the subsequent sending of the wet delay data text to the user for use, the user can identify which wet delay data corresponding to the wet delay parameters are recorded in the wet delay data text, and when a new blank document is injected with each wet delay parameter related to the wet delay agreed in advance as a column header, and a new header row is obtained, specifically, when each wet delay parameter related to the wet delay agreed in advance as a column header, the new blank document is injected, and a preset spacer is inserted between two adjacent column headers, so as to obtain the header row.
In practical applications, a person skilled in the art may also use other spacers according to business requirements, such as commas, semicolons, colons, and the like, which are not listed here, and the present embodiment is not limited thereto.
In addition, the number of the spacers inserted between two adjacent wet delay parameters is not limited in this embodiment, and in practical applications, those skilled in the art can set the spacers as needed.
For better understanding of the method for generating the text of the wet delay data provided based on the present embodiment, the following description is provided with reference to fig. 2:
firstly, a header line is injected, and preset observation station-satellite number parameter, observation station latitude parameter, observation station longitude parameter, observation station geodetic altitude parameter, navigation satellite system type parameter, inclined path wet delay parameter, satellite altitude angle parameter, satellite azimuth angle parameter and inclined path total delay parameter are sequentially injected into the header line as a header column according to a preset interval symbol, such as a blank space.
Thereby, the operation in step 101 is completed.
And step 102, determining the time division interval of the wet delay data which needs to be injected into the blank document according to a preset time measurement starting point, a preset time interval and observation data provided by an observation station.
Specifically, in this embodiment, the preset time measurement starting point is set based on the initial epoch time. For example, if wet delay data of 1 month and 1 day in 2019 is to be acquired, the preset time measurement starting point is specifically 0 minute and 0 second at 0 point of 1 month and 1 day in 2019.
Accordingly, the time interval may be substantial in terms of traffic demand, as well as required real-time, such as every few seconds, minutes, hours.
In addition, it can be understood that, in practical applications, the same observation station may observe multiple satellites, and the same satellite may also be observed by different observation stations, so that the observation data includes multiple pieces, and therefore, the observation starting time corresponding to each observation period and the observation data observed in the current observation period can be determined according to the preset time measurement starting point, the preset time interval and the observation data provided by the observation stations.
Still taking fig. 2 as an example, in the case that the time measurement starting point is "0 o 0 min 0 s at 1 st/h 1/2019", and the time interval is 1 s, the observation data provided by the observation station can be divided into the observation data of "0 o 0 min 0 s at 1 st/h 1/2019" and the data of "0 o 0 min 1 s at 1 st/h 1/2019", that is, the determined time interval of the wet delay data that needs to be injected into the blank document is two.
Further, through statistics, if there are 6 pieces of observation data corresponding to the observation time "0 min 0 s at 0 o 'clock 1/2019", the content of the last injected first wet delay data time division interlace is two parts of "0 min 0 s at 0 o' clock 1/2019" and 6, and in practical application, a specific format may be "2019110006" as shown in fig. 2.
If there are 3 pieces of observation data corresponding to the observation time "0: 1 second at 0 point 1/1 st day 1/2019", the content of the last injected first wet delay data time division interlace is "0: 1 second at 0 point 1/1 st day 1/2019", and "3", and in practical application, the specific format may be "2019110013" as shown in fig. 2.
Still taking fig. 2 as an example, 6 data lines need to be injected in the wet delay data time division line of "2019110006", and 3 data lines need to be injected in the wet delay data time division line of "2019110013".
And 104, injecting wet delay data corresponding to each column header acquired from the observation data into each data row.
Specifically, in order to make the wet delay data corresponding to each wet delay parameter recorded in the finally obtained wet delay data text clear and clear, so that when the wet delay data text is subsequently sent to a user for use, the user can quickly and accurately identify the required wet delay data, when the wet delay data corresponding to each column of titles acquired from the observation data is injected into each data row, a corresponding available column interval can be allocated to each title column, and then the extracted wet delay data is injected into the available column interval corresponding to each column of titles.
Regarding allocating a corresponding available column interval for each header column and injecting the extracted wet delay data into the available column interval corresponding to each column header, the following are specific:
determining the maximum column number occupied by the wet delay data corresponding to each column header;
determining an available column interval of the wet delay data corresponding to each column header according to the maximum column number corresponding to each column header and a preset interval symbol number;
injecting the wet delay data corresponding to each column header obtained from the observation data into the available column interval corresponding to each column header in each data row.
Taking the first row of wet delay data "GXNG-2N 32.5 E120.8805.8M G01.7047.1953338.90" under the row of wet delay data time separation of "2019110006" in fig. 2 as an example:
GXNG-2: occupying columns 1-10, wherein GXNG is an observation station, specifically occupying four characters, and 2 is a No. 2 satellite observed at the time of 0 minute 1 second at 0 point 1 day 1 month in 2019;
n32.5: occupying 11 th-20 th columns and representing that the latitude of the GXNG measuring station is 32.5 degrees in north latitude;
e120.8: occupying columns 21-30 and representing that the longitude of the GXNG station is 120.8 degrees from east longitude;
850.8M: occupying columns 31-40, representing a geodetic height of 850.8 meters for the GXNG survey station;
g: occupying columns 41-45, representing that satellite number 2 is a GPS satellite;
201.70: and columns 46-55 are occupied, and represent that the wet delay amount of the inclined path between the satellite No. 2 and the GXNG station at the time of 0 minute 1 second at 1 month 1 day 0 in 2019 is 201.70 meters.
47.19: occupying columns 56-65, representing an altitude angle of 47.19 degrees relative to the GXNG station for satellite No. 2 at the time 0, 0 minutes, 1 seconds on 1 month 1 year 2019.
5: occupying columns 66-75, representing a satellite number 2 with an azimuth of 5 degrees relative to the GXNG station at the time 0: 1 second on 1/1 of 2019.
3338.90: and columns 76-90 are occupied, and represent that the total delay amount of the inclined path between the satellite No. 2 and the GXNG station at the time of 0 min 1 s at 1/1 in 2019 is 3338.90 m.
It should be understood that the above examples are only examples for better understanding of the technical solution of the present embodiment, and are not to be taken as the only limitation to the present embodiment.
And 105, storing the blank document to obtain a wet delay data text.
Namely, the document which completes the operation is saved, and the wet delay data text can be obtained.
As can be easily found from the above description, in the method for generating a wet delay data text provided in this embodiment, the wet delay data text is constructed by using "observation station-satellite number parameter", "observation station latitude parameter", "observation station longitude parameter", "observation station geodetic altitude parameter", "navigation satellite system type parameter", "inclined path wet delay parameter", "satellite altitude angle parameter", and "satellite azimuth angle parameter" as column headers, and wet delay data matched with the column headers are injected into data rows corresponding to each column, so that the wet delay data is greatly enriched, and the problem that the existing wet delay information only includes distribution information of tropospheric wet delay in the three-dimensional direction due to zenith wet delay is solved.
In addition, in the method for generating the wet delay data text provided in this embodiment, since the wet delay information corresponding to the "inclined path wet delay parameter", "satellite altitude angle parameter", and "satellite azimuth angle parameter" is recorded in the finally generated wet delay data text, the user can perform three-dimensional modeling based on the obtained wet delay data text, so that the method can be better suitable for meteorological layer analysis and meteorological data analysis and forecast.
In addition, the method for generating the wet delay data text provided in this embodiment can acquire troposphere wet delay data information between each satellite and a single observation station from the wet delay data text based on the observation station-satellite number parameter, so that fine correction of influence of the single observation station on the troposphere wet delay between each satellite can be realized.
A second embodiment of the present invention relates to a method of generating a wet latency data text. The second embodiment is further improved on the basis of the first embodiment, and the main improvements are as follows: a wet lag data start line and/or a wet lag data end line is inserted into the document for subsequent use by the user.
For convenience of explanation, in this embodiment, as an example of a behavior of simultaneously inserting a wet lag data start line and a wet lag data end line into a document, as shown in fig. 3, a method for generating a wet lag data text according to a second embodiment includes the following steps:
It should be understood that steps 301 to 303 of this embodiment are substantially the same as steps 101 to 103 of the first embodiment, and are not described herein again.
In step 304, a first one of the wet delay data time division lines is determined.
Specifically, in order to facilitate the user who uses the finally generated text of the wet delay data to quickly locate the start position of the wet delay data, the wet delay data start line for informing the user of the start position of the wet delay data needs to be added to the first wet delay data time division line, that is, if the first wet delay data time division line is located on the third line of the whole document, a line needs to be inserted before the third line, the line number of the first wet delay data time division line is adjusted to the fourth line, and the newly inserted wet delay data start line is used as the third line.
Specifically, the preset start line identifier may be predetermined by a person skilled in the art according to needs, that is, the predetermined start line identifier is only required to be injected into the start line of the wet delay data.
For example, the "################################################################################################################isused as the preset initial line mark, namely, when the generated wet delay data text is used in the next time, the next line OF the line where the current mark information is located is the initial position OF the wet delay data as long as the generated wet delay data text is recognized.
It should be understood that the above examples are only examples for better understanding of the technical solution of the present embodiment, and are not to be taken as the only limitation to the present embodiment.
It is to be understood that step 306 and step 307 in this embodiment are substantially the same as step 103 and step 104 in the first embodiment, and are not described herein again.
That is, the wet lag data end line appears after all wet lag data is recorded, and the wet lag data for identifying the wet lag data recorded in the finally generated wet lag data text ends up at the wet lag data end line.
Specifically, the preset ending line identifier may be predetermined by a person skilled in the art according to needs, that is, the predetermined ending line identifier is only required to be injected into the ending line of the wet delay data.
For example, the "################################################################################################################isused as the preset ending row mark, that is, when the generated wet delay data text is used in the next time, the wet delay data text can be determined as long as the" ####################################################.
It should be understood that the above examples are only examples for better understanding of the technical solution of the present embodiment, and are not to be taken as the only limitation to the present embodiment.
And step 310, storing the blank document to obtain a wet delay data text.
It is to be understood that step 310 of this embodiment is substantially the same as step 105 of the first embodiment, and will not be described herein again.
For better understanding of the method for generating the text of the wet delay data provided based on the present embodiment, the following description is provided with reference to fig. 4:
firstly, a header line is injected, and preset observation station-satellite number parameter, observation station latitude parameter, observation station longitude parameter, observation station geodetic altitude parameter, navigation satellite system type parameter, inclined path wet delay parameter, satellite altitude angle parameter, satellite azimuth angle parameter and inclined path total delay parameter are sequentially injected into the header line as a header column according to a preset interval symbol, such as a blank space.
