XPLORA GNSS multi-system performance simulation environment

XPLORA, an OHB Digital Solutions product, is a highly flexible and powerful GNSS simulation environment that provides the possibility to generate simulated GNSS constellations and IF signals for various user-defined scenarios including complex trajectories and environments. All settings can be made within an easy-to-read configuration file or within the user-friendly and simple graphical user interface. The simulated signals can be used for evaluation of SDR receivers and GNSS applications and – in combination with a suitable RF signal generator – the evaluation of any hardware-based GNSS receiver is possible as well.

The system is composed of the following software modules:
– Orbit integration module based on earth gravitational model including gravitational effects of sun and moon
– Simulation of complete GNSS constellations including all satellites based on default almanac or accurate ephemeris information and clock parameters
– Simulation of accurate atmospheric models for ionospheric and tropospheric delays
– Simulation of user-defined receiver antenna characteristics including reception gain patterns and multipath effects
– Navigation message simulation based on GNSS ICDs or customized user-defined message formats
– IF signal simulation based on the constellation updates with user defined update rate and bandwidth
– 100% reproducible noise and signal degradation simulations
– Graphical user interface
– Comprehensive data logging of all intermediate results for detailed analyses and debugging support
