(1) Real-time closed-loop
The real-time closed-loop function is added, the carrier motion trajectory is received in real time, and the satellite navigation data are generated in real time, so as to meet the closed loop simulation test requirements of real-time hardware in the loop simulation system under multi signal system.
(2) Inertial navigation AIDS
The auxiliary receiver can capture, track and locate in high dynamic, with the addition of inertial navigation aid, synchronous output of 3d position, 3d speed and 3d acceleration with satellite navigation signal.
(3) Multi-path signal
Each frequency point can increase the output of 12 multi-path signals and main path signals.
(4) Carrier rotation simulation
When the carrier rotates, the satellite navigation signal changes.In order to make the satellite navigation receiving equipment in ground test, fully simulate the real movement situation.
(5) Multiple antennas
Increasing the number of simulated antennas, the single simulator can support the simulation of four antennas.
