%X The basic problem and the processing strategy about precise orbit determination of GPS navigation constellation were studied.From the observations of 148 IGS stations from March 29 to April 07 in 2008,one-day and three-day orbit solutions of GPS navigation constellation were determined.In order to evaluate the accuracy of the orbit,the orbit was compared with final orbit products produced by CODE.The results show that using this strategy,the one-day orbit solutions accuracy is better than 6cm in radical dir...
