The SIMAC6 from Accord Software & Systems is a GNSS Simulator that can simulate dual frequency IRNSS, GPS, GLONASS, BEIDOU, GALILEO along with SBAS and DGNSS augmentation systems. The system can simulate all the available GNSS satellites as per user selection, introduce signal anomalies like satellite orbit and clock errors, environment models for ionosphere and troposphere, different antenna models, receiver clock errors along with multipath and signal interference effects. It has 120+ configurable channels and independent receiver validation via NMEA data processing.
The simulator supports RS-232, RS-485 interfaces for DGNSS corrections, and the Ethernet interface for the diagnostic port. It can select single/multiple channels of GNSS constellations and is capable of multipath simulation. The simulator has navigation data modeling and supports error modeling for RAIM tests, waypoint navigation, and all types of vehicle simulation via motion commands or user motion/NMEA files. It is available in an enclosure that measures 482 x 545 x 266 mm and requires an AC supply of 230 V for operation.
