Permanent Link to Spectracom Offers GNSS Signal Generator for Production Testing
The GSG-51 GNSS signal generator provides a fast and cost-effective solution for production testing for Galileo and other GNSS. It emulates a single GNSS signal and can be upgraded for Galileo, as well as to increase the channel count, add receiver trajectory control, and add advanced features such as SBAS (WAAS, EGNOS,MSAS, or GAGAN), white noise generation, or multipath simulation. Its 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, for instance, in mobile phones with integrated GNSS receivers.
With a 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 for splitting the signal many times.
