Map matching augmented dead reckoning

Where am I? Where is my destination? How do I get there? These are questions commonly asked by all drivers. The Etak Navigator is an accurate, low cost and informative vehicle navigation system designed to answer these questions. The Navigator operates on a combination of dead reckoning and map-matching, map matching eliminates the accumulation of error attendant in all dead reckoning systems. The Navigator utilizes an on-board digital map data base which serves as input for the map matching process for finding the location of selected street addresses and for display. The combination of navigation and digital map technology opens new opportunities for useful products and services. Future special maps with Yellow Page information and routing will help individual drivers. An office-based map workstation can solve fleet routing problems or serve as the control center for real-time monitoring and dispatching of delivery or emergency service vehicles.
