driftsonde in flight

Anasphere's Driftsonde System

The driftsonde system uses high-altitude balloons to carry dropsondes over inaccessible areas to conduct meteorological measurements. The payload consists of two parts: a command box, which includes a satellite communications system for command and data relay, and a launcher, which (in the original design) could carry up to six dropsondes based on the AnaSonde-2G. The dropsondes measure pressure, temperature, humidity, wind speed, and wind direction; they can also accommodate extra user-added sensors.

In operation, the system is launched with a zero-pressure balloon which attains altitudes between 80,000 and 90,000 feet. It then drifts along on prevailing winds, and dropsondes can be released on command. Dropsonde data is sent to the command box, which forwards it via satellite link to a remote location. Upon completion of the mission, the balloon is deflated and the payload is released to descend under a parachute.

The driftsonde system is ideal for taking soundings in remote or hard-to-access areas, such as over oceans and polar regions.
