| Abstract: | The reason of ITRF computation inconsistency at normal equation level and the advantage of combination computation at observation level are analyzed. After summarizing the research status of combination computation at observation level, the solution procedure and key issues of combination computation at observation level are analyzed. In order to overcome the computing difficulty of combination computation at observation level, the combination computation strategy based on distributed process is advanced. And then the parallel computing flow and method of the ITRF solution are designed. The study results show that the ITRF solution strategy at observation level can improve the product consistency and the distributed process technique can improve the efficiency of ITRF solution. |
| Keywords: | ITRF the observation level consistency distributed process |
