LOHAN is a madcap project involving using a high-altitude balloon to launch a glider to the edge of space then have it released from the balloon and navigate itself down to a designated landing spot. The unit needed a way to communicate when out of normal GPRS coverage.
Data buoys are sent into the water for a wide variety of reasons and will be equipped with technology designed to collect and transmit information along the buoy’s journey.
Edorado High School sends instrumentation packages, called Eagles, to the edge of space and transmits back temperature, pressure, and GPS data, as well as live video. In all, twenty different data channels are telemetered back to 'Mission Control' in the classroom.
Drifting Buoys are versatile kits that anyone with the know-how can use to retrieve their own oceanic data. Generally, the main purpose of drifting buoys is to measure ocean currents and sea temperatures, the data of which is then transmitted back to research labs on the mainland for analysis.
