Abstract
A method of locating a moving element by determining a reference position and at least one overall protection limit on the basis of data from a group of satellites in a constellation of satellites. The method comprises the steps of selecting from the group of satellites a subgroup comprising at least five satellites, calculating positions from the data from the group and from the data from the subgroup, and calculating corresponding protection limits while distinguishing whether the failure in the constellation does or does not affect the satellites under consideration.
