The Core Flight System (cFS) is a software package that I have written to one day be used in a weather balloon which I plan to launch to around 100,000 ft, 3 times the height of a comercial airliner. The primary objective is to take photo’s of the curvature of Earth.

The cFS stays in permanent contact with ground control via http requests (below 10,000 – 30,000ft) and then via a series of beeps over radio wave. When the balloon reaches its maximum altitude it will pop and parachute back to Earth and at somewhere between 30,000 – 10,000ft http communication between the balloons cFS and Ground Control will be regained and the ground control software will automatically download photos and data logs from the cFS.
