A rotating beacon system and a method for synchronizing multiple rotating
beacons. The rotating beacon system includes two or more rotating beacons
and a feedback based control system adapted to sense an angular position
of each of the two or more rotating beacons and generate two or more
digitally controlled currents, each of the two or more digitally
controlled currents conducted to an associated rotating beacon, the two
or more digitally controlled currents driving and controlling the angular
speed of each of the two or more rotating beacons to regulate a
pre-selected phase relationship between multiple beacons.
