摘要
Procedure whereby a GPS receiver calculates the spatial and temporal position of a moving object in a predetermined reference system, this position being calculated on the basis of data supplied by at least four satellites of the GPS system selected by the GPS receiver in order to form a so-called calculation constellation. This procedure includes a step of estimating the error made in the position calculation, this estimation being carried out by the GPS receiver for each calculated position, so that the estimation of the error made varies with the position of the moving object.
