| Abstract: | In this paper, the formulae of local parameters are firstly derived under the network-solution and the PPP-solution conditions, respectively. If the weight matrix of global parameter in PPP-solution is small enough, the expression of local parameters are the same as that in network-solution. Then, 16 daily solutions are obtained in both PPP mode and network mode. Three sites are selected to compare their solution differences. The experimental results demonstrated that their difference between two solutions in coordinates and tropospheric delays are only few millimeters. |
