Estimation of an individual position

A device that comprises:

• an interface that is configured to receive position measurements from one first positioning system and position measurements from at least one second positioning system,
• at least one processor that is configured to perform the following steps:
• providing at least one first position measurement from the first positioning system,
• providing at least one second position measurement from the at least one second positioning system,
• providing a third position measurement from the first positioning system that temporally follows the first and second position measurement,
• providing an autocorrelation order A for position measurements by the first positioning system, and
• estimating the individual position depending on at least the third position measurement and at least one position error value that is determined on the basis of at least one first position measurement and the at least one second position measurement;
• wherein
• the individual position is estimated on the basis of at least the third position measurement and A position error values that are determined on the basis of A first position measurements and A second position measurements.
