Abstract

On the basis of adding normal equation method,the one day-long delayed global station's data and real time regional station's data have been synchronously dealed for navigation satellite orbit determination.Compared with the IGS precision orbit,the average of 3D RMS of the computed near real-time orbit is 14 cm,and the average of 3D RMS of the near real-time prediction orbit is better than 30 cm.
