<p>A buoy with a drift tracking system meant to monitor the position of a moored floating ocean observation platform is provided. The drift tracking system comprises a first trans-receiver adapted to acquire position co-ordinates of the buoy, a memory adapted to store information related to an initial position co-ordinates of the buoy, a comparator adapted to compare the initial position co-ordinates with a present position co-ordinates of the buoy and a first switch adapted to change an operating mode of the drift tracking system between a normal mode and a drift mode, wherein in the normal mode the first trans-receiver is adapted to acquire position co-ordinates of the buoy at a first rate and in the drift mode the first trans-receiver is adapted to acquire position co-ordinates of the buoy at a second rate.</p> |
