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.

[What is claimed is:] [1.]position determining means for determining a measured position of the satellite positioning receiver based upon pseudo-random code measurements of received satellite signals, wherein each measured position is determined by the determining means at each of a series of measurement times that are separated from each other by a predetermined interval of time;velocity determining means for determining measured velocity of the satellite positioning receiver by Doppler-effect measurement based upon satellite carrier signals detected by the satellite positioning receiver; andmeans for extrapolating corrected intermediate positions of the satellite positioning receiver between two measured positions based on the first occurring measured position of the two measured positions and the measured velocity.
