The portable satellite navigation simulator adopts a powerful computing platform and a reconfigurable and configurable architecture design, which can flexibly configure and output signals from different system navigation frequency points, and supports simulation of four system full frequency band navigation satellite signals. At the same time, the equipment is equipped with a highly stable clock module, which can be fully synchronized with the actual Satellite navigation, and can realize the simulation of the real satellite navigation signal in the outfield environment, so as to facilitate the detection and troubleshooting of the outfield Beidou/GNSS navigation terminal.
The device has the characteristics of portability, miniaturization, simplicity, and ease of use, with a total weight (including battery) of no more than 5kg. It is suitable for applications such as outdoor real satellite simulation, rapid navigation signal verification, and backpack operation. Equipped with outfield Test automation evaluation software, it can meet the requirements for the detection and fault diagnosis of various functions and performance indicators of Beidou/GNSS navigation terminals in the outdoor environment.
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.| 模擬信號頻段 | |||
