| Abstract: | This paper discusses theoretically the stability of solutions for dynamic geodetic network adjustment,Kalman filtering and sequence adjustment,and two examples are given.The solution for dynamic geodetic network adjustment is stable if the dynamic geodetic network is a classical network.There is not rank deficit in datum,or else the solution is not stable,which will depend on the initial value. |
