Transmitters used in drifters gather information for day to day weather reports ocean current studies and research on climate change. They are also used to track land and sea creatures and racing yachts.

Moonraker drifters have been used with notable success to study the East Australian Current, revealing huge eddies, almost as big as Tasmania, with a lifetime of at least 18 months. 2,000 km of the path of a current, now known as the Leeuwin Current, was traced out off Western Australia. Deep-drogued buoys have been used to study winter warming and eddy kinematics in the Bay of Biscay in the North East Atlantic.

Moonraker's satellite tracked drifters have an excellent performance record and history of longevity with battery operated units still operating months after their anticipated lifespan. the Argos satellite data-relay system is fully enclosed in a cylindrical buoy hull and provides standard sea surface temperature, battery level and drogue loss indication sensors with air temperature and atmospheric pressure sensors as options.

Moonraker moored platforms are in use by the military protecting harbours, and the like. Buoys are self contained and powered to support underwater equipment like mine systems, and provide a radio relay to another station. The hull shape provides a stable platform for the antenna and solar panels with minimal acoustic noise when moved by wind or wave action. The system is designed for deployment and recovery up to Sea State 2, operation up to Sea State 4, and survivability up to Sea State 6.
