    • Abstract
  • The paper analyze the GPS ephemeris,on the base of comparing EKF to UKF,a hybrid orbit prediction method is investigated based on UKF in this paper.It is shown that UKF is more stable,and improved the orbit predicted precision.It offers a new idea for some others satellites orbit determination as Galileo.
