1. Introduction
Global Positioning System (GPS) is all weather, worldwide, continuous coverage, most modern, sophisticated and state of art yet simple and user friendly Satellite based navigation system [1]. GPS is a frontier and cutting edge Technology. Its application in Military and civilian purpose is tremendous and ever increasing. Since it’s inception it has grown to provide not only worldwide, all-weather navigation, put precise position determination capabilities to all manner of users. The resulting precision available exceeds any previously attainable without large expenditures of time and resources. Few of the many applications include precise timing, position fixation, survey, navigation, auto landing etc. If present trends are of some indication then it is amply clear that GPS is all set to invade all aspects of human life. It has inherent potential to cater much more than what it is catering today. Lots of Research and developmental activities are going on around the world to explore the avenues of opportunities pertaining to the application of GPS. In view of its global and wide range of application the more we talk about GPS the lesser it is. Unlike any other technology it has carved a niche for itself and likely to revolutionize the way of thinking. As a technology it has got a vital role in Integrated Test Range applications. For the flight evaluation of any test object, it’s time and space position information plays a crucial role in determining its performance against pre-determined trajectory parameters. In this regard, Test Range has got a prime role in delivering the accurate time and space position information data to the designers. The capabilities of GPS technology, in terms of data accuracy, speed of data availability and reduction of test operating cost moved Integrated Test Range to make an investment and integrate itself with GPS [1]. 2. Range Calibration methodology Test Range has got a prime role in providing the accurate time and space position information data to the designers/users. Thus requires an accurate calibration source for tracking instruments. As performance of various test vehicles are evaluated presently using various tracking instrumentation systems like optical/Infrared, Radar, Telemetry, DGPS (Differential Global Positioning System) has a prime role in calibrating these trackers.
