32-channel L1/L2 GPS/GNSS Simulator

Available from Spectracom

Spectracom's GSG-62 offers multiple frequency band operation, multiple GNSS constellation simulation, and expansion to more channels. GSG-62 is future-upgradeable to more frequency bands and channels (plug-in hardware) and more signal formats (firmware).

Configure scenarios on-the-fly without the need for an external PC and pre-compilation phase. Via the front panel, users can modify parameters such as user position, time and specify output powers in carrier-to-noise ratio instead of absolute output power. Utilizing the white noise generation extends usability and flexibility. Optional StudioView™ software facilitates easily created scenarios via a Google Maps interface.

The GSG-62 multi-channel simulator makes it possible to simulate all the visible satellites for the receiver under test. With 16 channels for L1 and 16 channels for L2, these channels can be assigned to either GPS or GLONASS, P-code or C/A code. Or some of these channels can be used for SBAS simulation of EGNOS, WAAS, GAGAN, or MSAS satellites, or for simulating multipath or interference.

GSG-62 is perfect for a wide-variety of test cases including:
-Testing of military SAASM receivers and high-end survey grade civillian receivers.
-Test of simulated movements (user trajectories).
-Test of receivers’ sensitivity to loss of satellites, multi-path, leap seconds, and atmospheric conditions.
-Test of timing receiver accuracy, dynamic range, and susceptibility for noise (SNR limit testing).
