Airborne surveying with Doppler system
Self-contained navigation systems based on familiar "Doppler effect" provide precise, automatic direction of aircraft over predetermined flight path, with accurate side-lap and over-lap control; advantages resulting from fewer reflights, and elimination of ground based aids, are reflected in better accuracies and lower costs of Doppler survey operations.
