Spectracom GSG-Series GNSS Simulators have added capability to provide multiple RF outputs for advanced testing where multiple receivers or antennas are in use in a single system. Typical examples include controlled radiation pattern antennas (CRPA) or heading/attitude receivers and systems.
The intuitive StudioView software allows easy reconfiguration of test cases to change the conditions seen by one or all receivers and antennas under test — for example, adding a jamming signal to one antenna input on a CRPA receiver. Both over-the-air testing or cabled capabilities are available.
Because the simulator operates independently of PC control, the simulators can be precisely synchronized with a common clock and trigger pulse. There is no theoretical maximum to the number of RF outputs. This flexibility also allows testing multiple rovers reporting into a single control system, such as asset tracking or personnel location management systems.
This advanced feature is offered in both the L1 band GSG-5 series simulator for commercial applications as well as multi-band GSG-6 series simulator for professional applications.
