EF-ATLEC multi-instruments gondola for balloon flights in stratosphere in conjunction with satellite TARANIS mission" MG & ES /LATMOS In frame of preparation of TARANIS mission (CNES micro-satellite; launch: ~2015; geosynchronous orbit at ~700 km) we are developing multi-instruments gondola for the CNES balloon flights in equatorial, mid-latitude stratosphere. The idea is to carry in-situ observations of lightning and associated stratospheric discharges (TLEs blue jets, elves, etc.) simultaneously and in conjunction with the satellite observations in the ionosphere. For this purpose we are developing a multi-instruments autonomous gondola for the balloon flights with low power instruments that required high data rate acquisition and accurate dating. The LATMOS EF-ATLEC gondola consists of the electric field instrument SDA (DC-few kHz), photometers, 3D cameras, sound recorder. The concept of this gondola is planned to be used by other high data rate instruments on Cobrat/Taranis balloon project, like search-coil magnetometers and gamma detector. Preliminary tests of multi-instruments gondola with two onboard instruments (SDA of LATMOS and Field Mill of SPRL/Michigan) were performed in 2011 during CNES campaign in Kiruna/Sweden. Results and future developments are discussed.
