The Nav3D simulation software for satellite occlusion and multipath effects in complex environments is based on real-world modeling and simulation scenarios, simulating the propagation effects of GNSS signals in specific environments. We have independently developed a complex geometric and physical editor that uses the creation of 3D synthetic environments or real 3D maps, combined with ray tracing technology, to calculate and analyze the propagation path of GNSS signals in complex environments. It is the first in China, Benchmark similar Sim3D simulation software products from abroad.
During Nav3D simulation, satellite navigation signals will interact with the real 3D environment, simulating the real signal path, and controlling the simulator to output realistic RF signals. The actual output signal includes the shielding of the street, Viaduct, canyon and other surrounding environments from the satellite direct signal; One or multiple reflections from the ground, trees, buildings, mountains, canyons, and other factors on the satellite, including reflection angle, area, and reflection coefficient, are simulated to simulate the power attenuation and delay of possible multipath signals. The relevant signals can better meet the requirements for signal occlusion and multipath effects in high-precision and anti-interference testing.
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.|
