When the processing engine 112 transmits data (e.g., positioning results) to the user terminal 130, the processor of the processing engine 112 may generate an electrical signal encoding the data. The processor of the processing engine 112 may then send the electrical signal to an output port. If the user terminal 130 communicates with the processing engine 112 over a wired network, the output port may be physically connected to a cable that may further transmit the electrical signals to the input port of the server 110. If the user terminal 130 communicates with the processing engine 112 over a wireless network, the output port of the processing engine 112 may be one or more antennas that may convert electrical signals to electromagnetic signals. In an electronic device, such as user terminal 130 and/or server 110, when its processor processes instructions, issues instructions, and/or performs actions, the instructions and/or actions are performed by electrical signals. For example, when a processor retrieves or stores data from a storage medium (e.g., storage device 140), it may send electrical signals to a read/write device of the storage medium, which may read or write structured data in the storage medium. The configuration data may be transmitted to the processor in the form of electrical signals via a bus of the electronic device. Herein, an electrical signal may refer to an electrical signal, a series of electrical signals, and/or one or more discrete electrical signals.

In a positioning display interface corresponding to the map positioning module 240, the line display can be realized; displaying the track of the mobile station; selecting a map expected area; displaying a field intensity thermodynamic diagram; the positioning result probability ellipse shows and other effects, that is, the map interface of the mobile station positioning subsystem 200 can show the movement track of the mobile vehicle, the change of the level value in the moving process and the instant direction-indicating direction. When positioning is started, estimation of the position of a transmitting source can be obtained through mobile station direction line data at different positions by using a single-station positioning algorithm, and a positioning result is displayed through a probability ellipse.
Through tests, when the mobile station positioning subsystem of the embodiment realizes positioning, under the condition that the direction-finding function meets the condition that the direction-finding accuracy is less than 3 degrees, the first positioning time can be further realized to be less than 3 minutes, and after a vehicle moves for 15 minutes, the typical value of the positioning accuracy reaches 1 km.
In some embodiments, the mobile station positioning subsystem may implement acquisition of a signal to be detected based on a corresponding signal monitoring system, for example, may implement preliminary screening of the signal to be detected based on a wireless signal acquired by the signal monitoring system, specifically, determine the signal to be detected based on information, such as a start-stop frequency, a scanning step, a manual threshold, and the like, of the signal to be detected, which is acquired in advance from data acquired by the signal monitoring system.
The signal monitoring system can be an existing system capable of realizing wireless signal monitoring, and in some embodiments, the signal monitoring system can realize the correctness of data display of a scanning frequency spectrum and a waterfall chart during frequency band scanning; during single-frequency measurement, the accuracy of monitoring and monitoring a single frequency point, the accuracy of intermediate frequency data, audio data and IQ data, and the accuracy of displaying compass data are obtained when single-frequency point direction finding is carried out on a specified frequency. In some embodiments, the signal monitoring system may further extract signals with a level greater than a manual threshold, which are shown in a signal list.
