| Abstract(in English) | We recommend ionosphere-free combination for ambiguity resolution in network-based GPS system for our investigation of the ionospheric effect. Although correction data generated from reference stations network were applied for the user station, ambiguity resolution was terribly poor for ionosphere. The ionospheric delay had not been estimated precisely by interpolation. So we applied ionosphere-free combination for ambiguity resolution and positioning. Ambiguity success rate had pretty improved, from about 70% by conventional method to more than 80% by ionosphere-free combination. Furthermore, ionosphere-free combination achieved highly precise positioning result. Thus, it was appeared that ionosphere disturbs ambiguity resolution and precise positioning even if reference stations network were adjusted, and that ionosphere-free combination is really effective in this case. |
