GSG-51 Single Channel GNSS Tester

Single-channel GPS/GNSS 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.

GSG-5 Series Multi-channel Advanced GNSS Simulator

Multi-channel GPS/GNSS L1 RF Generator

The GSG-5 series is a GPS, GLONASS, Galileo, BeiDou, and QZSS constellation simulator that generates all commercial signals in the standard L1 band. It offers the standard set of features for testing GNSS systems. With a base of four channels, configurable and upgradable to 8, 16, or more signals, this configuration is the perfect fit for navigational fix and position testing, for in-line product testing or engineering and development.

GSG-6 Multi-Channel, Multi-Frequency Advanced GNSS Simulator

Multi-channel, Multi-Frequency GPS/GNSS RF Generator

The GSG-6 Series family offers multiple frequency band operation, multiple GNSS constellation simulation, and expansion to many more channels. Incorporating all of the features of the popular 5 Series family, the 6 Series line expands your capability to simulate all the new, emerging GNSS signals. With a base of 32 channels, upgradable to 48, 64, or more, it provides navigational fix and position testing, for engineering and development testing. The 6 Series simulator protects your investment by being upgradeable in the future to more frequency bands and channels (plug-in hardware upgrade) and more signal formats (firmware upgrade).

GSG StudioView Software

GPS/GNSS Test Scenario Builder Software for Windows®
