The NSS9000 series GNSS constellation simulator is a new generation positioning, navigation, and timing (PNT) simulation system that supports full constellation and multi frequency GNSS signal simulation. The constellation, signal, and carrier models are configured through NavSim software, which can simulate and generate high-precision and high dynamic RF signals. At the same time, it has strong user on-site upgrade and flexible configurable ability, and can flexibly configure any GNSS constellation frequency point signal output according to user requirements.
The NSS9000 adopts a high-performance large-scale real-time parallel computing software and hardware architecture, supporting up to 512 hardware channels. The channel capacity can meet the simultaneous generation of GNSS full frequency signals, with a data update rate of 1000Hz and real-time performance better than 1ms. It can fully meet the high-precision positioning, high dynamics, navigation and timing testing needs of aerospace, aviation, and other fields.
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.|
