Préparation de la nacelle de servitudes opérationnelles (NSO)

Preparing the operational service gondola. Situated in the core of the flight assembly, the operational service gondola receives and transmits data between the airborne and ground-based segments, and controls the aerostat (stratospheric balloon) in flight. The operational service gondola contains the flight avionics components, including the onboard computers, transponder and ballast container. In particular, these gondolas enable the actuation of gas- or ballast-releasing devices, to control the balloon's ascent and descent. Data received by the control centre on the ground indicates the balloon's position as well as the status of its onboard systems.
