Abstract :
The Drifting Buoy Location System is a system for Lagrangian tracking free drifting buoys using high frequency radio signals. Up to 400 different buoys may be tracked using time multiplexing. An audio tone, derived from a stable oscillator, modulates the high frequency transmitter on the buoy. This signal is received at three or more receiver sites and the received tone is compared to reference tone. The phase differences of these signals are used to locate the buoys.
