The NPS4000 adopts navigation digital signal fast demodulation, solution processing technology, and high-precision positioning, navigation, and time service signal simulation technology, which can automatically identify deceptive interference signals in the free space environment, provide timely warnings, remind users, and quickly switch navigation signals or eliminate interference signals to avoid interference to the backend GNSS navigation time service terminal, resulting in deviation or error in the output reference clock information. The NPS4000 can be connected in series between the original antenna and timing equipment, without the need to change the original timing equipment and antenna system.
NPS4000 can help users build a secure and powerful defense system, enabling them to better monitor, respond, defend, and eliminate threats, ensuring the normal operation of the system timing network.
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.|
