Workshop 2017 - Fei Ye - In order to get rid of the dependence on the predicted orbit products and reduce the strong correlation between user location, satellite orbit and clock parameters. We use the joint solution on broadcast ephemeris, user station and global evenly distributed reference network, which can real-time estimate user location, satellite orbit and clock correction parameters. Moreover, satellite orbit and clock correction parameters can broadcast to other users to achieve PPP algorithm. On the basis of the global reference network of 40 stations, the experimental results of 20 user stations show that the static and dynamic real-time positioning accuracy of the algorithm is 1cm and 10cm, respectively.
