1. A method of providing by a computer server of errors in calculating a position corrected by user receivers of positioning signals received from at least one constellation of satellites in a determined geographical zone, said method comprising:

  • determining a list of contributing receivers of positioning signals situated in said geographical zone, a position of said contributing receivers not being known a priori;

    extracting, for each of the contributing receivers Ri, code Ci and phase Φ

    i data of at least one channel of the contributing receiver;

    calculating an atmospheric error Ii applicable to each contributing receiver Ri on the basis of said code Ci and phase Φ

    i data;

    calculating an atmospheric error I(Zj) applicable in the zone Zj, on the basis of the errors Ii applicable to the contributing receivers Ri; and

    making available to at least one of the user receivers the calculated atmospheric error I(Zj) applicable in the zone Zj for correction of the positioning signals.
