Long Duration Balloon flight from polar regions(Peterzen et al. ESA Symposium 2003 ESA-SP530 – St. Gallen)
Workshop ASI sulle Tecnologie ElettroOtticheASI 14/10/2004 S. Masi
Flights from NSBF - USA
(from Fairbanks, Alaska)
At similar latitudes,
flights from Kiruna (Sweden)
Svalbard have higher latitude.
Long Duration Balloon flight from polar regions(Peterzen et al. ESA Symposium 2003 ESA-SP530 – St. Gallen)
Workshop ASI sulle Tecnologie ElettroOtticheASI 14/10/2004 S. Masi
Flights from NSBF - USA
(from Fairbanks, Alaska)
At similar latitudes,
flights from Kiruna (Sweden)
Svalbard are at higher
latitude (78-80N).
Svalbard launch tests
Test launch July 24, 2004
Feasibility of LDB flight from Svalbard proved
More than 40 days at float
IRIDIUM telemetry subsystem for OLIMPO succesfully tested
Solar panels/charge control tested
Forecasted OLIMPO LDB scientific balloon flight in Summer 2006

Telemetry / TC / data acquisition for Long Duration Balloon Flights
Polar flights are not in Line of Sight.
Solution:a) Satellite relay telemetry / TC systemIridium TM/TC for selected/compressed data (INGV, G. Romeo/Phys.Dept)b) on-board full storagec) data dump on selected ground stations
