Abstract:To resolve the challenge of the current contradiction between the demands of large GNSS network data processing and existent processing capabilities and strategies, a new network solution algorithm\|Ambizap\|which is based on fixed point theorem, is introduced in this paper. We then introduce distributed computing technology into GNSS data processing. The distributing processing flow of large GNSS network data based on the Ambizap algorithm is designed and achieved through use of NET framework distributed technology under the distributed environment. The accuracy of the Ambizap algorithm and the efficiency of its distributed application are verified through some examples. The results show that the distributed processing of Ambizap can effectively resolve the contradiction currently faced by large GNSS network data processing, bringing a more efficient and economical processing method.
Keywords:PPP  double differencing  fixed point theorem  Ambizap  distributed computing
