Pendulum GSG-51

GSG-51 GNSS Signal Generator

Single-channel GPS L1 RF Generator

The GSG-51 is a GNSS signal generator that emulates a single satellite signal. The main application is a simple but very fast manufacturing test, to assure that the assembly is correct, that the antenna is properly connected, and that the receiver can receive and identify a satellite signal. It provides a fast and cost-effective solution for production test of GNSS-receivers in e.g. mobile phones with integrated GNSS-receivers. Thanks to the wide RF level range from –65 to –160 dBm, the sensitivity of all types of GNSS receivers can be verified with a minimum of delay. The 60 dB of extra power from normal test scenarios allows from splitting the signal many times.
