Abstract :
The Hunter Vehicle Tracking System (VTS) is presented. The block diagram of the system is presented, and elements of the in-vehicle unit (IVU) and the dispatch control-unit (DCU) are studied. Some practical considerations about the communications links are presented. Map database generation from common geodetically referenced data sources such as the 7.5-min USGS quads is discussed. Implemented as a geodetically referenced system, the VTS can accept inputs from sensors of navigational receivers such as GPS (Global Positioning System) and Loran-C. A comparison of results between GPS and Loran is presented
