GNSS emulation system
This system allows emulating the signals from GPS (L1 and L2), Galileo (E1, E5ab and Safety of Life) and GLONASS (L1) at a RF level. The system is controlled using the SimGen software and a wide variety of parameters can be modified (antenna patterns, multipath, ionospheric and tropospheric propagation models, etc.). The software SimInertial can simulate the inertial and barometric sensor data including their typical errors. The complete system can be run in real time and remotely which makes it a good choice for Hardware in the Loop (HIL) tests of aerospace navigation systems.
