Mobile Data Communication in Land-Based Positioning, Navigation and Surveying Applications

Thomas T. Yang, Kai Yan Yip

Abstract:	This paper examines the role of mobile data communica- tion in land-based positioning, navigation, and surveying applications. Land-based positioning, navigation, and surveying applications can be classified into six types, based on the following functions: (1) monitoring, (2) data collection, (3) route searching, (4) data services, (5) traffic control, and (6) dispatching. It is not unusual for an ap- plication to belong to more than one of these types. Land-based positioning, navigation, and surveying appli- cations require communication between field mobiles and a central control location or, in some cases, among mo- biles. A possible exception to this is a data collection application where data is stored within the mobile and is post-processed. The integration of positioning and navi- gation technologies with mobile data communications allows more sophisticated applications to be developed. Positioning is the most important element in all land- based positioning, navigation and surveying applications. This paper introduces mobile data techniques that improve positioning accuracy. A field study of a land-based positioning and navigation application using MOBITEX@ wireless wide area net- works is presented. The benefits of using MOBITEX and land-based positioning, navigation and system perform- ance are also discussed. The paper then concludes with the description of a field study and recommendations for future system designs.
