Description of the payload

The balloon carried a payload of approximately 3 kg composed of a ARGOS transponder with a GPS board and a Lithium battery pack.

The flight plan called for the balloon reach float altitude and circumnavigate the polar region between 78 and 80 deg. N. Throught the GPS/ARGOS payload the trajectory would be traced showing the stratospheric circulation pattern of stratospheric winds, and providing information about diurnal excursions, and potential termination/impact locations for the future LDB flights.
