Mission Concept

The system is designed to operate for 5 h, with a flight time of about 2 h. A gondola with the system will be attached to a helium balloon with in the regulations of the balloon class ”light”. On a sunny day it will then be launched from the campus site of the Technical University Munich in Garching. In flight the system has a downlink which provides information about the position. All payload data and and a set of telemetry data will also be send. After an ascent of roughly 2 h the balloon will explode, because of the pressure difference of in and outside. A rapid descend follows. With the attached parachute a descent velocity of about 10 m/s is to be expected. During the whole flight
a mobile ground station in addition to the LRT roof antenna will track the position. This will help with a fast recovery of the system after descent.
