Aerosonde

The Aerosonde is a small low cost autonomous aircraft for sounding in remote areas. It typically carries instrumentation to measure temperature, pressure, humidity and wind vector. It has fantastic range and endurance (> 2500 km > 30 hours). Newer versions are developed and produced by Aerosonde .
