Abstract
A method for estimating accuracy of a position determination based on distance-dependent measurements is disclosed. The method comprises: storing area information in relation to pre-defined geographical areas, wherein the area information for each pre-defined geographical area includes accuracy information relating to accuracy of position determinations based on distance-dependent measurements in the pre-defined geographical area; receiving a request for an accuracy estimate; determining an area affiliation based on received position information in said request, wherein the area affiliation defines at least one applicable geographical area among the pre-defined geographical areas, wherein the position of the receiving unit is located within the at least one applicable geographical area; and determining the accuracy estimate based on the stored area information for the at least one applicable geographical area.
