    Abstract
  • Taking common commercial software TBC and HGO as carriers, load precision and broadcast ephemeris are respectively resolved. Fifty-seven baselines are randomly selected for analysis in this paper, and the adjustment results are compared with the acknowledged data. It shows that for GPS networks of grade C, the results of loading a broadcast ephemeris with the software are reliable.
