GPS-Based Mobile Information Service Over MOBITEX Networks

George She

Abstract:	Since the introduction of the Global Positioning System (GPS) by the U.S. government in the late 80’s, many different applications have been developed to utilize GPS for position determination and navigation purposes. These applications include military electronic warfare, marine navigation systems, aircraft landing systems, vehicle navigation systems, and personal location systems. The position information derived from the GPS receiver in a remote/mobile system can either be used by the remote user or be relayed to a host system in a back office for further processing and manipulation. The MOBITEX network, a terrestrial two-way wireless packet data network that has been deployed in many countries worldwide, can be extremely useful for relaying such positioning information from the remote system to the host system. Use of MOBITEX networks for positioning and navigation can be beneficial in a variety of applications, such as monitoring of mobile systems, dispatching systems, mobile information services, route management, and vehicle control/security systems. In the area of personal applications, users can employ MOBITEX networks to efficiently transport positioning information to public safety authorities or medical service providers in case of emergency, as well as to incorporate the information in messages for wireless e-mail or two-way interactive paging systems. The broad features of the MOBITEX system and the concept of the system design for the GPS-based Mobile Information Service application are presented.
