GSS7790 Advanced Multi-Output, Multi-Channel GPS Simulation System
"A GPS simulator developed specifically for CRPA anti-jam development utilizing an anechoic chamber RF range."
The GSS7790 allows the signal from each satellite to be mapped to a physical RF output. These signals can then be fed to individual antennas which when suitably deployed in an anechoic chamber support the development and test of Controlled Reception Pattern Antenna (CRPA) systems.
Spirent has supplied such systems in North America as well as in Europe and Asia. Contact us for further details and testing advice.
Typical Applications
- CRPA and system testing: Installation inside anechoic chamber and attachment to multiple transmitting antennas to recreate a simulated live environment for testing entire CRPA systems including the antenna element itself
- CRPA control unit testing: Integrated with multi-element phase shift or delay matrix to produce RF wavefront at multiple simulated antenna elements
- Radiated testing: Environment emulation using reflectors and signal attenuators to test actual antenna performance in an anechoic chamber
- Indoor GPS emulation
- Wavefront applications
