Navigation aid for main battle tank (MBT) training simulators

Combat Vehicles Research and Development Establishment (CVRDE) has developed Arjun MBT simulator to impart tank level training to the Commander, Gunner and Driver. In the simulator, the route navigation is being done by the commander using the Global positioning System (GPS). The GPS used in MBT has been adapted to the simulator with route navigation page, compass page, feeding of way points and shortest path calculation for commander´s decision making. Since the actual GPS cannot be used in the simulator, a workable solution was carried out by emulating the GPS receiver hardware and mimicking the functionality of the system in software. This paper focuses on the design and its implementation carried out in the simulator for the GPS simulation requirements.
