in a specific embodiment, the information content carried in the first configuration information and the second configuration information may be consistent or inconsistent; the consistent condition means that the first configuration information and the second configuration information carry all configuration information which can be configured by the control software subsystem, which is equivalent to that the control software subsystem sends two identical configuration files to the navigation signal simulation subsystem and the communication signal simulation subsystem, and the navigation signal simulation subsystem and the communication signal simulation subsystem acquire the configuration information required by themselves after receiving the configuration files. The inconsistent situation means that the control software subsystem respectively sends the required configuration information to the navigation signal simulation subsystem and the communication signal simulation subsystem, for example, the navigation signal simulation subsystem needs to send the GNSS navigation message to the navigation fusion application terminal, so that time information, constellation information, frequency point information, user track information and communication interaction configuration information in the configuration information are needed; the communication signal simulation subsystem needs to send a low-rail communication signal to the lead fusion application terminal, and needs communication node configuration information, navigation data configuration information and time synchronization information.
The constellation configuration information at least comprises constellation and frequency point information; the terminal configuration information at least comprises user track information; the error configuration information includes at least: navigation data and time synchronization information; the communication configuration information includes at least communication node information. The configuration information in the control software subsystem in the embodiments of the present application is used to control and configure the navigation signal simulation subsystem and the communication signal simulation subsystem.

the communication signal simulation subsystem is used for generating a low-rail communication signal based on the second configuration information and sending the low-rail communication signal to a to-be-tested generic fusion application terminal; wherein the low rail communication signal includes at least one of: SPT navigation data and navigation precision correction data.

in specific examples the navigation messages include satellite ephemeris, clock bias, ionosphere parameters, etc.; the observed data may include pseudoranges, carrier phases, doppler shifts. The observation data is used for channel delay simulation and simulates a signal transmission process of transmitting real satellite signals to a ground receiver terminal.
The navigation signal generation module is used for generating a navigation intermediate frequency signal from the navigation message and the observed data and transmitting the navigation intermediate frequency signal to the radio frequency module;
it should be noted that, the navigation intermediate frequency signal is generated by the navigation message and the observation data, so that the navigation intermediate frequency signal can be sent to the navigation fusion application terminal after up-conversion through the radio frequency module, that is, the navigation intermediate frequency signal or the GNSS navigation signal after up-conversion processing is carried substantially.
The radio frequency module is used for carrying out up-conversion processing on the navigation intermediate frequency signal to obtain a GNSS navigation message, and sending the GNSS navigation message to the navigation fusion application terminal.
Therefore, the navigation signal simulation subsystem in the embodiment of the application provides the GNSS navigation message for the lead fusion application terminal so that the lead fusion application terminal can perform navigation positioning, and prepares for subsequent test of the lead fusion application terminal.
In general, in an optional implementation manner of this embodiment of the present application, the navigation simulation module in the navigation signal simulation subsystem may be further configured to generate simulated SPT (Security Positioning and Timing, secure positioning time service) information and simulated navigation precision correction data based on the first configuration information, and send the simulated SPT information and the simulated navigation precision correction data to the communication signal simulation subsystem in combination with the visible ephemeris synchronization of the lead fusion application terminal.
The simulated SPT information is used for assisting the GNSS to perform navigation positioning and is used for GNSS navigation positioning backup information, that is, the simulated SPT information not only can assist the GNSS to perform navigation positioning so as to achieve the purpose of rapid convergence, but also can be used as low-precision backup information of GNSS navigation positioning, and can also realize low-precision positioning when no GNSS navigation signal exists. In addition, the navigation precision correction data in the embodiments of the present application include track and clock correction, code deviation and carrier phase deviation, and troposphere and ionosphere corrections. The navigation precision correction data in the embodiment of the application is used for testing the high-precision positioning function and performance index of the lead fusion terminal.
It can be seen that, in the embodiment of the present application, the SPT information and the navigation precision correction data required by the communication signal simulation subsystem may be provided by the navigation simulation module in the navigation signal simulation subsystem, and in other examples, the communication signal simulation subsystem may also obtain the required SPT information and the navigation precision correction data from the outside (such as a ground base station data center).

the communication simulation module is used for sending a low-rail communication signal to the intermediate-frequency signal processing module based on the received processed communication request signal;
the intermediate frequency signal processing module is also used for processing the low-rail communication signal and then sending the low-rail communication signal to the second radio frequency module;
the second radio frequency module is also used for carrying out up-conversion processing on the processed low-rail communication signals and then sending the processed low-rail communication signals to the lead fusion application terminal.
It can be seen that the communication signal simulation subsystem of the embodiment of the present application may receive a communication request signal from the fusion application terminal, where the communication request signal is used to request corresponding data (precision correction data for requesting positioning navigation or communication data for performing voice or text). The communication simulation module processes the low-rail communication data through the intermediate frequency signal processing module based on the communication request signal, and then up-converts the low-rail communication data into a low-rail communication signal to be output to the lead fusion application terminal, so that full-duplex communication test is realized.
Combining the SPT information and the navigation precision correction data required by the communication signal simulation subsystem provided by the navigation simulation module in the navigation signal simulation subsystem, or acquiring the required SPT information and the navigation precision correction data from the outside by the communication signal simulation subsystem, processing the voice, the data, the SPT navigation information and the navigation precision correction data into digital information by the communication simulation module in the communication signal simulation subsystem, transmitting the digital information to the intermediate frequency signal processing module, generating a communication intermediate frequency signal by the intermediate frequency signal processing module according to a communication request signal, and outputting a low-rail communication to a communication fusion application terminal by the radio frequency module.

the positioning accuracy can be evaluated by comparing the measured positioning result of the lead fusion application terminal with the actual position of the true calibration. And comparing, analyzing and evaluating the signal power according to the power of the signal received by the lead fusion application terminal in real time and the power requirement required by navigation positioning. Navigation integrity refers to the assessment from receiver sensitivity, accuracy and reliability of receiving and processing navigation signals.
The communication test module is used for testing the connection performance of the communication link, the quality of communication data and the transmission performance of the communication data based on the configuration information and the processing result; the communication data in the embodiment of the application comprises SPT navigation data and navigation precision correction data and other data used for communication.
The connection performance of the communication link may refer to evaluating the communication transmission speed and stability, among other things. The audio and speech quality assessment may be assessed from speech intelligibility, volume, noise suppression functions. The data transmission performance can evaluate the speed, reliability and delay of data receiving and transmitting of the lead fusion application terminal.
And the navigation fusion application testing module is used for testing the navigation positioning mode of the navigation fusion application terminal based on the configuration information and the processing result.
It should be noted that, the conducting fusion application terminal in the embodiment of the present application may perform positioning in three modes of PPP (Precise Point Positioning, precise single-point positioning), RTK (Real-Time Kinematic), ppp+rtk, so that the conducting fusion application test module may test indexes such as convergence Time, positioning precision, dynamic performance, robustness of positioning performance, etc. of the PPP, RTK, PPP +rtk positioning function.
In a specific example, the fusion application terminal is used for performing PPP positioning based on navigation precision correction data (which may also be referred to as GNSS precision correction data), that is, satellite signals (low-orbit satellites and medium-high-orbit satellites) are received through a GNSS receiver and transmitted to a server for data processing and calculation, and then, the factors such as star position and clock error information, delay of an earth ion layer and the like are utilized, precision calculation is performed through multi-frequency observation data, and a more accurate position result can be obtained under the correction of the navigation precision correction data.
In a specific example, the navigation fusion application terminal for performing RTK positioning based on navigation precision correction data refers to real-time calculation and correction by using differential signals between a reference station (or base station) and a mobile station (subscriber station). The reference station accurately measures the position thereof and transmits differential data to the mobile station, the mobile station performs real-time calculation and correction through differential observation data between the mobile station and the reference station, and more accurate position calculation can be obtained under correction of navigation precision correction data.
Furthermore, the high precision of PPP and the real-time property of RTK are combined in the PPP+RTK mode, after the initial position is obtained by using single-point PPP positioning, the RTK technology is utilized for real-time dynamic satellite signal correction and updating, and the positioning precision and the position stability are further improved.
