Abstract
In a method for relative time and position determinations for moving objects of a constellation, signals by the objects are isochronously transmitted, with each object transmitting a unique signal for that object. The received signals of each object of the constellation are transmitted to all other objects of the constellation after a predetermined waiting time.
