GS-SIM200 GNSS Simulator

GNSS Signal Simulation

The GS-SIM200 GNSS Simulator supports all possible scenarios, from simple setups with static satellites all the way to flexible scenarios generated in real-time with up to 80 dynamic GPS, Glonass and BeiDou satellites.

Key Features

  • + Support of GPS L1/L2 (C/A code), Glonass L1/L2 and BeiDou2 B1/B2/B3, including hybrid constellations
  • + Signal attenuation control
  • + Real-time status display, satellite status, motion trajectory view
  • + RF cable interface, forward antenna interface, optional wireless mode or wired mode

Testing GNSS receivers reliably

The signal strength of individual satellites can be controlled in real-time in order to simulate conditions of restricted satellite visibility. The set of satellites to be simulated is continually calculated based on the number of available channels, the satellite visibility and the constellation geometry. The satellite visibility can be influenced by the user by configuring an elevation mask.

Two method of setting the moving trajectory

The GS-SIM200 can simulate a moving user in various ways, trajectories can be defined in the form of waypoints, or they can be imported and played back using routes that were recorded in NMEA format with a GNSS receiver.Another approach to motion simulation is to feed externally generated trajectories (i.e. from outside the GS-SIM200) via SCPI to the GS-SIM200.

Simulation of realworld conditions

Ionospheric effects, tropospheric influences, signal obscuration and multipath effects are among the key factors that can impact the quality and availability of GNSS signals. Using the GS-SIM200, such influences can be quickly and easily configured to obtain a realistic simulation of receiving conditions.
