Constellation simulation: ability to complete satellite orbit simulation, satellite clock error simulation, delay differential TGD simulation, earth rotation effect simulation, relativistic effect simulation, etc.
Trajectory simulation: has static and dynamic trajectory generation capability, and can simulate the motion characteristics of sports carriers such as vehicles, ships, and aircraft. At the same time, it has special scene simulation functions such as spirals.
Environmental simulation: ionospheric delay simulation, tropospheric delay simulation, ground atmospheric parameter simulation, etc.
Simulation control: independent setting capability of pseudo-range and power for each channel, generating navigation and telegram capability for the constellation model, and setting parameters for atmospheric layer and ionospheric model parameters.
Multi-frequency point output: supports signal simulation output of any frequency combination of four satellite navigation systems.
Multi-function: optional components including inertial navigation, interference signals, spoofing signals, real-time closed-loop simulation, optical fiber communication interface, serial timing component and scam signal integration to achieve the corresponding test functions.
