Abstract�� To solve two problems on micro-nano satellite that the dates of position and velocity is not consecutive for using global position system(GPS) individually and the errors of position and velocity radiate rapidly using orbital dynamics, a novel method of position determination for low earth orbiter( LEO) micro-nano satellite based on nonlinear model predict filter (MPF) was proposed. In this method,MPF predictd the errors of model which is because orbital dynamics modle is not precise as the first step of estimation, and the informations of GPS on satellite as observations, then combined with extended Kalman filter (EKF)which was improved to obtain the position and velocity not only consecutively but also precisely as GPS for single point position. Simulations show that, it is effectively to get position and velocity consecutively, and the pricition is better than EKF.
