In order to achieve these objectives the FTB_1 vehicle had to autonomously track a
predefined longitudinal trajectory.
More in details the mission can be schematically described as follows 11 :
1. the FTB_1 vehicle (Castore) is carried to the launch site and poised for
launch under the balloon gondola;
2. the stratospheric balloon is dynamically launched;
Figure 2.3 – Schematic illustration of the FTB_1 experimental vehicle launch sequence (Ref. 11).
3. the stratospheric balloon carries the vehicle to an altitude of about 20 km
inside a safe Release Zone 15 ;
