GNSS / GPS Simulation Software

GNSS Simulation Software, for all your needs: XPLORA Core

XPLORA Core is a GNSS simulator for novices and experts alike and covers all your needs: testing and validating GNSS hardware, research or satellite constellation simulation. Benefit from quickly created simulations and parameters that can be adjusted down to the smallest detail for more complex test scenarios. Configure satellite orbits, navigation-messages and change simulation parameters on-the-fly or in a hardware-in-the loop setup. Improve your interference and spoofing countermeasures and mitigation strategies by using highly detailed signal simulations.
