Abstract :
Based on cellular mobile net, TDOA positioning algorithm has been demonstrated by many parties in the recent years, however, low degree of accuracy compared with GPS limits its usage in vehicle positioning and navigation services. Here we introduce two assisted technologies, the digital road and the dead reckoning, to improve the performance that of TDOA. This paper discusses on the methods and feasibility of the TDOA-based assisted technologies application and introduces the vehicle management system concerned. It has been compared with the traditional sole positioning algorithm and given the simulation. The future prospect of this system is discussed
