Abstract
A GPS satellite signal receiver fitted on an aircraft. Velocity measurements are used to obtain position values at a sufficient rate to provide position extrapolation while waiting for the next position measurement. A corrected position is provided on the basis of a measured position by adding to the preceding corrected position, the velocity integrated between two times and a smoothing term which is a fraction of the difference between the measured position and the corrected position at the preceding position measurement time.
