The Strategy for GPS Lost Positioning
並列摘要
This paper presents a novel, real-time, positioning algorithm for integrating GPS and INS in plane motion. The proposed method not only deals with GPS lost positioning, but also positions the location of the vehicle at least ten times per second. Where the INS only adopts one two-axis accelerometer and its drift error is compensated by GPS. In general, the three cases of GPS lost positioning are (1) while the GPS positioning report rate is only 1 Hz, in the interval of one second between neighboring reports and there being no positioning output; (2) GPS could not position itself following one minute after supplying power; (3) a huge building could shadow the GPS satellite signal in the city, such as when the GPS loses positioning. This paper proposes the integration algorithms of GPS/INS where (a) the GPS provided the last known location of vehicle; (b) INS uses (a) and itself measuring the acceleration to ascertain the current location. The function of INS can increase the positioning report rate by up to 10Hz; (c) GPS will correct the INS positioning once each second to reduce the drift of the INS positioning.
