Abstract:	GPS technology has found widespread applications in varied walks of life. GPS receivers serving these applications require among other performance factors, maximum possible sensitivity under non-conducive environments. Both acquisition and tracking sensitivities play an important role in determining the overall performance of a GPS Receiver. As sensitivity is a function of various elements, it is important to analyze these parameters to study their impact on receiver sensitivity performance. This paper describes the theoretical basis for acquisition algorithms and tracking loops to improve the overall sensitivity of the receiver. Extensive simulations and experiments were carried out to ascertain the level of improvement obtained. The programmable architecture on the NAV2KTM family of GPS receivers facilitated easy implementation of the improved algorithms onto the GPS core. Extensive bench tests were then conducted to verify and validate the results.
