Whether you’re a beginner or an experienced user, XPLORA Core is the GNSS simulator that meets all your needs. It’s perfect for testing and validating GNSS hardware, conducting research, or simulating satellite constellations. With XPLORA Core, you can quickly create simulations and adjust parameters to the smallest detail for more complex test scenarios. You can configure satellite orbits, navigation messages, and change simulation parameters on-the-fly or in a hardware-in-the-loop setup. And, by using highly detailed signal simulations, you can improve your interference and spoofing countermeasures and mitigation strategies.

The XPLORA Core is a versatile and user-friendly modular software tool capable of generating all public GNSS signals and frequencies currently available. With its direct RF signal playback and digital IF-based signal generation capabilities, users can access real-time signal playback. Additionally, the tool offers a GNSS receiver observable simulation that can be customized to meet user needs, including optional signals, frequency bands, and interference and multiple receiver simulations.
