Abstract
An arrangement for correcting errors incurred in airborne navigational systems. A ground installation in the form of a radar determines the positions of a multiple number of aircrafts, and communicates the positional information of the aircraft, simultaneously to all aircrafts involved. Each individual aircraft, thereupon, compares the position determined by its own navigational system, with the position communicated from the ground radar. On the basis of the resultant comparison, the navigator of each individual aircraft, is enabled to correct his position and compensate for the error inherent in the airborne navigational system.
