WebThe modern drifter is a high-tech version of the "message in a bottle". It consists of a surface buoy and a subsurface drogue (sea anchor), attached by a long, thin tether. The buoy measures temperature and other properties, and has a transmitter to send the data to passing satellites. The drogue dominates the total area of the instrument and ... WebThe transmitter is fitted with a high gain antenna in order to achieve maximum transmission range. Now the receiver unit is developed using a n atmega microcontroller and display in order to receive data transmitted by the transmitter buoy and display it.
