Gps-based land vehicle tracking and monitoring system

摘要

A land vehicle tracking and monitring system based on the integration of differential global position system (DGPS), dead-reckoning (DR), and map matched tech- nology is studied. In this paper, from the economic point of view, a new scheme using the one-way directional com- munication link, is presented. Moreover, 8-state Kalman filter is proposed for integrated DGPS/DR system. When field tests are carried out using two C/A code GARMIN GPS receiver, the positioning accuracy less than 5 m (1σ) Is achieved.
