Error Prediction for SINS/GPS after GPS Outage Based on Hybrid KF-UKF

Error Prediction for SINS/GPS after GPS Outage Based on Hybrid KF-UKF

The performance of MEMS-SINS/GPS integrated system degrades evidently during GPS outage due to the poor error characteristics of low-cost IMU sensors. The normal EKF is unable to estimate SINS error accurately after GPS outage owing to the large nonlinear error caused by MEMS-IMU. Aiming to solve th...
