Abstract: Based on satellite-bone GNSS,the precision orbit determination(POD) for low earth orbit satellites is becoming one of hot spots in the realm of geodesy and geomatics.It is also one of means of POD for the domestic earth-oriented satellites.In this paper,accuracy evaluation methods used currently are discussed in details as well as their advantages and disadvantages.The experimental results are carried out so as to verify the related methods on different conditions and to check their validity and limitations.
