Satellite navigation signal source software is a platform used for simulation scene management and simulation process monitoring.
NavSim satellite navigation signal source software is a platform used for simulation scenario management and simulation process monitoring. Its function is mainly to model and simulate various factors that affect the dynamic characteristics of the downlink navigation signal of the Satellite navigation, calculate the dynamic parameters of the signals reaching the observation epoch at the receiver antenna interface, and drive the signal generation unit to output continuous and stable satellite downlink navigation signals, Assist in verifying the signal layer and information layer of the receiving device, as well as testing its functional and performance indicators.
NavSim主要是通过对影响卫星导航系统下行导航信号动态特征的各种要素进行建模仿真，计算得到到达接收机天线口面处各观测历元的信号动态参数，并驱动信号生成单元输出连续稳定的卫星下行导航信号，辅助完成接收设备的信号层、信息层验证以及功能、性能指标测试。
The scripted editing ability of the testing plan planning function and testing process allows users to plan and design the testing plan according to the testing requirements before the experiment, and edit the testing process. Users can manage and configure the testing scenarios and processes according to the testing needs of different receivers and different testing tasks and objectives, and use them as different testing templates.
Perform manual or batch Test automation based on test scenarios and test processes, and have one click Test automation function for user terminal technical indicators.
After each test project is completed, it can automatically analyze and evaluate the test data and generate test reports, with the function of automatic analysis and evaluation of user terminal technical indicators.
Multiple testing and evaluation modes are available, including automatic, manual, and single mode.
Real time analysis and evaluation of test data, capable of analyzing and comparing test data in real time, completing functional and performance indicators such as pseudo range measurement accuracy, positioning accuracy, channel consistency, bit error rate, etc., and automatically generating data processing reports.
The real-time analysis and evaluation function of test data allows for knowing the statistical results of indicators without waiting until the end of the test, facilitating the timely termination of problematic receiver tests and saving testing time.
Comprehensive display function: It can comprehensively display various information such as work status, simulation scenarios, positioning results, data processing reports, etc. in various forms such as data, tables, graphics, etc.
Database management function, which can automatically classify, store, query, and count simulation and test data, and has automatic data storage and retrieval functions.
Equipped with automatic evaluation of test results and automatic generation, printing, and export of test reports.| 仿真信号规模 | |
