The GNSS Software for Open- and Closed-Loop Simulation is application software that supports simulation of different GNSS RF types including GPS L1 coarse/acquisition (C/A), Galileo E1, and GLONASS G1 for automotive, space, defense, or aeronautics applications. You can use this add-on to implement trajectory in open- or closed-loop using National Marine Electronics Association (NMEA) and keyhole markup language (KML) file formats. Additionally, the GNSS Software for Open- and Closed-Loop Simulation helps you create or perform verification and validation (V&V) of positioning systems.
