Integration of data and correlation meter speed strapdown inertial navigation system built by analogy with the Doppler velocity and drift, results in strong disturbances in the control loop movement of the aircraft in the horizontal plane. A method of aggregation, which takes into account the correlation method for measuring the speed, is the need to calculate the long periods of correlation functions of signals received by antennas spaced. This corrected the error strapdown inertial navigation system to speed up, speed and coordinates, eliminating the need for a moving average of the correlation functions and information retrieval speed navigation in every cycle.
