1. Full-element modeling and simulation technology

Through self-developed simulation software (such as BeamSpaceSim), full-element modeling of the absorbing materials, antennas, turntables and other entities in the anechoic chamber is carried out to accurately simulate the electromagnetic environment. This technology can quickly complete the performance analysis of the anechoic chamber quiet zone, detect potential interference areas in advance and optimize the design to ensure the stability and accuracy of the test environment.

2. Zero-delay switching technology between satellite signal antennas

It has solved the problem of pseudo-range hopping caused by signal switching in traditional anechoic chambers, achieving seamless switching of satellite signals between different antennas. It supports long-term continuous simulation and high-precision anti-interference testing, meeting the performance evaluation requirements of navigation terminals in complex electromagnetic environments.

3. Panoramic 3D visualization real-time monitoring and analysis evaluation

For the first time, panoramic 3D visualization technology was introduced, presenting the test scenarios, processes and results in an intuitive 3D animation form, supporting users to monitor the status of the equipment, the distribution of interference signals and the changes of test data in real time. Meanwhile, by integrating digital twin technology to achieve intelligent operation and maintenance, system faults can be automatically located and visually alerted, significantly enhancing testing efficiency and maintainability.

4. The ability to simulate complex electromagnetic environments in multiple scenarios

It can simulate real satellite navigation signals, various interference signals (such as suppression interference and spoofing interference) and dynamic scenarios, covering multiple system frequency bands such as Beidou and GPS, and meet the performance testing requirements of navigation terminals for positioning and anti-interference in complex electromagnetic environments.
