Abstract:	The NAVSTAR Global Positioning System (GPS) provides worldwide positioning service to 2-Dimensional, 95 percentile accuracies of 100 meters for the Standard Positioning Service (SPS) for civilians and about 15 meters for the Precise Positioning Service (PPS) available to authorized users only. In the past, GPS has been combined with other instruments, such as Inertial Navigation Systems (INS) and Doppler radars for navigation, and precise frequency standards for timing, to produce more robust and accurate integrated system. Within the past few years, significant advances have been made in GPS receiver and wireless communication (comm) technologies. Handheld devices for GPS and Personal Communication Service (PCS) have decreased in size and cost, yet increased in capability and battery life. This paper analyzes the benefits and discusses conceptual design issues associated with a tight integration of GPS with II wireless communication link for both military and civilian users. In addition to providing a means for data and voice communication, the comm link can provide GPS initialization data that could significantly improve GPS acquisition and navigation (nav) performance, especially in stressed (interference prone) environments.
