GPS/GNSS Simulators

Multi-Channel Multi-Frequency GNSS Simulators

GSG-6 Series of multi-channel, multi-frequency advanced GNSS simulators offers multiple frequency bands, multiple GNSS constellation simulation, and expansion to many more channels. With a base of 32 channels, upgradable to 48, 64, or more, it provides navigational fix and position testing. The GSG-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).
