Intelligent Sensor Integration Algorithms for Vehicles

Philip G. Mattos

Abstract:	Whilst the integrated navigation system has been used for years in aircraft, in cars the problems of very slow speed, obstruction/reflection from buildings, and resolution requirements measured in metres rather than 100’s or 1000’s thereof combine with formidable cost constraints. The open motorway presents no problems, but the congested inner city at 1Omph does. Previous systems have switched from GPS to dead-reckoning, yielding the worst of both worlds to achieve continuous coverage. A solution is presented that uses the best features of both to calibrate the speed, distance and direction sensors and also minim& the effects of SA when both systems are available, and when GPS is unavailable, to continue with minimum degradation.
