| Abstract: | Satellite laser ranging(SLR) is one of the commonly adopted techniques to track low Earth orbit(LEO) satellites and support precise orbit determination(POD).The influence of the length of data arc on the POD accuracy by using global SLR data from Jason-1 and ENVISAT satellite is investigated,and the orbit accuracy of POD solutions based on regional SLR data is analyzed.Those regional data are from American,European and Asian SLR networks.The reference orbits of Jason-1 and ENVISAT satellites used to assess ... |
