Abstract: Global Positioning System (GPS) devices are useful for location tracking applications, where these devices act as a receiver with satellite transmitting the location data and the receiver goes for trilateration technique for pointing out the precise device location. This process requires the devices to be tuned to precision. In commercial development and testing of GPS systems or devices, it’s extremely necessary to have testing equipment so as to test the under development GPS devices at lower price and also with minimum labour and ease. The newly developed GPS devices need to undergo a precision test, to know how precisely these devices can locate the location, their speed of operation, one way of obtaining the result is to go for real time testing with the device take around the place and pointing to the open sky to know how perfectly the device model is working, this type of testing always calls for lot of labour, cost and not feasible most of the time. Our proposed idea suggests a virtual simulation of the GPS devices, where a combination of software and hardware model is used for testing of GPS devices. This type of technique does the same task of real time testing but without the device been taken around, this makes the testing cost effective, easy, labour free and feasible at all conditions in the laboratory.
