SQUARE ROOT-HIGH DEGREE CUBATURE KALMAN FILTER WITH APPLICATION TO INERTIAL SENSORS FUSION WITH LOW ORBIT SATELLITE SIGNAL

摘要

Static Test Results: Indium position converges to the centre of the circular zone which approximately 36-467m the GPS location of the Tracker. The problem of increasing accuracy in the static mode could be solved by geometrical solution which leads with circle fitting algorithms on the basis of multiple measurements of Iridium location estimation. The CKF with High degree cubature rule presented the best RMSE performances compared with SPKF and EKF. The accuracy achieved 36 meters instead of 1 km.
