| Abstract: | It is explored how to use grid to fast resolve multi session GPS carrier phase measurement. Firstly, the least squares method is used to derive an adjustment model for the multi session GPS carrier phase measurement, the model quality of being decomposable is analyzed, and it is decomposed into several sub computations. Father the grid workflow formed by these sub computations and the way to realize the workflow are discussed. Finally, a 4 session baseline is resolved by using a single computer and a grid, respectively. The experiment results show that the Grid method is feasible and can increase the computing velocity by many times. |
