Vehicle dynamics conditioning method on MEMS based integrated INS/GPS vehicle navigation system

摘要: A method of compensating performance low-cost MEMS (microelectro mechanical systems) inertial sensors in an integrated INS/GPS navigation system for automotive application is disclosed. The proposed includes velocity and sensor output conditions featured ground vehicle dynamics. Using the conventional Kalman filter based system, implementation prescribed present invention additionally to GPS measurements shows accurate motion tracking even when signal dropouts last more than 2 minutes. Another aspect disclosure which utilizes maintaining high position accuracy a lost or unavailable long period time by incorporating predefined dynamics calculating optimum estimates through filtering process.
