Low-Cost Automotive Navigation Alternatives

Daniel N. Aloi and Jeff Stefan

Abstract:	Typical automotive navigation systems require an on- board digital map database, Global Positioning System (GPS) receiver, and a dead reckoning sensor suite. These systems are expensive and complex, and have met with resistance in the consumer space. An alternative approach is to adapt great circle navigation methods while maintaining a digital map database on an external server. This paper explores the algorithms and technology required to exploit this navigation method. Issues covered are road geometry mitigation, reliance on GPS as the single navigation sensor, off-route detection and correction algorithms, and cellular infrastructure issues.
