MaxEye GNSS Simulator
Advanced GNSS Simulation with multi-constellation and multi-band capabilities ideal for GNSS testing in Automotive, Defense and Aerospace applications. NavikEye Multi-constellationGNSS simulator is scalable and fully customizable software for GNSS test and measurements at every stage of the product development cycle from design, production to deployment.
NavikEye Multi-constellation GNSS Simulator offersrealtime generation of various global satellite navigation signals including dynamic scenarios and HIL simulation. The scenario generation can be fully automated using the remote TCP commands via Ethernet. This enables the implementation of dynamic HIL environment. The HIL test system can feed the realtime location coordinates, velocity and other vehicle dynamics to the GNSS Simulator. Based on this GNSS simulator updates the receiver position in realtime.
The simulator supports moving receiver scenarios with predefined waypoints using NMEA and KML files.NavikEye GNSS Simulator is based on National Instruments scalable and software defined PXI architecture powered by LabVIEW.
