A SYSTEM AND METHOD FOR AUGMENTING A SATELLITE-BASED NAVIGATION SOLUTION |
摘要 |
A map-matching feedback interface uses added information to bound a mapping solution and calibrate a navigation system, thus enabling the navigation system to navigate more accurately over a longer period of time. The system recognizes erroneous measurements and reduces or eliminates them from the mapping solution, thus preventing position inaccuracies. The system interfaces the navigation system with a mapping system that feeds back map-based data to the navigation system and combines the map-matching feedback data with other sensor data to produce an accurate navigation solution even in environments where GPS or dead reckoning input data is inaccurate. |
