1. A GPS positioning system, comprising:
- at least one mobile station to measure a positional coordinate by receiving radio wave from a satellite;
a plurality of fixed stations that have predetermined positional coordinates and receive radio wave from the satellite; and
arithmetic processing means, which is connected with at least one mobile station and a plurality of the fixed stations via communication, and that transmits correction data suitable for the mobile station to the mobile station based on positioning data transmitted from the mobile station.

7. A data server for GPS positioning, comprising:
-
a communication interface that receives positioning data from a mobile station whose positional coordinate is measurable by receiving radio wave from a satellite;
a line interface whose positional coordinate is fixed at a known point, and that receives positioning data from a plurality of fixed stations that receive radio wave from the satellite;
storage means that stores data regarding correction; and
arithmetic processing means that reads out suitable correction data from the storage means and transmits the correction data to the mobile station based on the positioning data received via the communication interface. - View Dependent Claims (8)
