About Spectracom's GNSS Simulators

The GSG-5™ and GSG-6™ Series of GNSS Constellation Simulators provide a wide-range of capabilities for in-line production testing and development testing, including navigational fix and position testing, while offering ease-of-operation.

GSG-51 is a single-channel GPS L1 RF generator, capable of emulating a single GNSS signal. One of the main applications for these cost-effective units is fast manufacturing testing of GPS receivers.

GSG-5 Series simulators reproduce the environment of a GNSS receiver. Depending on the configuration, these units simulate up to sixteen GNSS satellites, up to 3 SBAS satellites, together with optional multipath and interference signals. The GSG-5 Series applies models to simulate satellite motions, atmospheric effects, and different antenna types. The movement of the GNSS receiver under test is defined using NMEA data or pre-defined trajectory models.

GSG-6 Series simulators add advanced features and the capability to simulate up to 64 satellites (configuration-dependent) on different frequency bands simultaneously. New signal types include GPS L2P, L2C and L5, GLONASS L2, Galileo E1 and E5a/b, BeiDou B1 and B2, and QZSS L1 C/A, L2C, L5 and L1 SAIF, IRNSS L5.
