A STUDY ON THE POSSIBILITY OF A HIGHLY-ACCURATE NAVIGATION SYSTEM USING ONLY GPS

The possibility of guiding and directing motor vehicles by exhibiting courses on the display panel of a navigation system using a global positioning system (GPS) receiver and map-matching algorithm was investigated. To guide and direct motor vehicles accurately, it is essential to locate vehicle position on the road of a digital map. Map-matching technique is needed that will correct the measured position of a vehicle to the position calculated on the map. A velocity vector calculated from the GPS receiver was considered for input data for map-matching. Positional deviation from accurate positions on the roads of the digital map shown on the display panel was obtained to investigate the positional accuracy of vehicles under the system using map-matching technique. It was found that the positional deviation from the road shown on the display panel during time periods when GPS measurement was possible was around 10 m and that accurate guiding and directing of vehicles can be made possible be using the GPS receiver and map-matching technique.
