ER-S-8000 Multi-System Satellite Navigation Signal Simulator
Introduction
ER-S-8000 Multi-System Satellite Navigation Signal Simulator can simulate BDS, GPS, GLONASS and Galileo global satellite positioning system (GPS) satellite navigation signals, can be used for many systems compatible with the terminal equipment development, production, testing, testing and inspection.
Function
- Frequency points supported by the product include Beidou Satellite Navigation System (BDS), B1, B2, B3, GPS L1 and L2 and L5, GLONASS L1, L2 and Galileo E1, E5a, E5b frequency points (choose 3 to 11 frequency points).
- Using configuration data simulation software, simulation data can be configured according to user requirements, such as satellite orbit data, ionosphere, tropospheric parameters, and trajectory users.
- The control software is used to interrupt the output signal of the satellite navigation signal simulator, restore the signal, switch the visible star signals, select the modulation mode, and control the power.
- Evaluation software can test the receiver’s first positioning, speed, sensitivity and positioning time and other indicators; abnormal conditions can simulate satellite pseudo ranges to test the receiver’s autonomous functions.
- LCD display content: carrier information such as satellite number, channel number, analog time, doppler, pseudorange, satellite power, location, and vehicle speed.
- The navigation signal can be output via cable or antenna.
Optional Configuration
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 is 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.
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.
Multi-path signal, each frequency point can increase the output of 12 multi-path signals and main path signals.
Carrier rotation simulation, when the carrier rotates, the satellite navigation signal changes. In order to make the satellite navigation receive the signal, the equipment fully simulates the real movement in the ground test.
Multiple antennas, increasing the number of simulated antennas, the single simulator can support the simulation of four antennas.
