GNS8340 Multi-constellation Navigation signal Simulator
Technical specification
GNS8340 multi-constellation simulator is a multi-constellation multi-frequency analog source for global satellite navigation system, which is designed and developed for various user computers, production testing, teaching demonstration, equipment testing and routine testing applications.
The GNS8340 multi-constellation simulator provides satellite navigation signal simulation for global satellite navigation systems. 12 satellite signals per frequency, supports signal simulation output of BD / GPS / GLONASS / GALILEO constellations combined with arbitrary frequency points, provides high stability standard 1PPS pulse signal and 10MHz clock signal output. It can meet the application needs of various types of integrated navigation user terminal equipment design and development, production testing, teaching demonstration, equipment testing and routine testing.
It can complete satellite orbit simulation, satellite clock error simulation, delay differential TGD simulation, ionospheric delay simulation, tropospheric delay simulation, earth rotation effect simulation, relativistic effect simulation, ground atmospheric parameter simulation, user trajectory simulation, etc.
It has static and dynamic trajectory generation and testing capabilities; independent setting of pseudo-range, power and carrier initial phase for each channel; generating navigation message capability for constellation model; multi-path signal simulation capability; programmable signal scene generation capability; atmospheric layer and ionospheric model parameter setting capabilities; as well as observation data and navigation message recording and output functions.
The carrier frequency, code rate, information rate, pseudo range initial value, and carrier phase of each channel can be set independently.
The simulator is stable, mainly for power calibration, users need to have universal testing instruments, such as spectrometers and oscilloscopes. We will train the user how to calibrate. If the user needs, within guarantee period, simulator can be returned to the factory for full system calibration.
