Cascaded Expandability: Cascadable with GNSS global satellite navigation constellation simulators to enhance simulation flexibility and application scope.
Full-Scenario Simulation: Covers low-orbit constellation layout, time group delay (TGD), Earth rotation, relativistic effects, satellite clock error and other key scenarios.
Environmental Effect Simulation: High-precision simulation of ionospheric delay, tropospheric delay and ionospheric scintillation (adaptive to ground/space carriers).
Remote Control & Interaction: Equipped with standard network ports, supporting remote control and data interaction for automated testing and remote operation.
Physical Channel Simulation: Replicates characteristic parameters of various physical channels to improve the authenticity and effectiveness of signal simulation.
Expandable Testing & Evaluation: Supports terminal simulation verification and joint debugging, including configuration management, command control, data reporting and test case invocation.
High-Precision Clock Synchronization: Adopts high-precision disciplined atomic clock technology to ensure the clock accuracy of simulated signals, meeting high-precision navigation requirements.
