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主要是通過對影響衛(wèi)星導(dǎo)航系統(tǒng)下行導(dǎo)航信號動態(tài)特征的各種要素進(jìn)行建模仿真，計(jì)算得到到達(dá)接收機(jī)天線口面處各觀測歷元的信號動態(tài)參數(shù)，并驅(qū)動信號生成單元輸出連續(xù)穩(wěn)定的衛(wèi)星下行導(dǎo)航信號，輔助完成接收設(shè)備的信號層、信息層驗(yàn)證以及功能、性能指標(biāo)測試。
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.
