1. A method applied in a Global Navigation Satellite System (GNSS) for minimizing storage of correction data, comprising:
- determining a receiver position and at least a satellite position;
determining an intermediate point between the satellite position and the receiver according to the receiver position and the satellite position, the intermediate point being located at an elevation between an elevation of the receiver position and an elevation of the satellite position, and a position of the intermediate point changing when either the receiver position changes or when the satellite position changes;
determining a current cell of the intermediate point that is defined around the intermediate point according to the position of the intermediate point; and
storing the correction data sets related to the current cell.
