The CNES Balloon division has been developing the superpressure balloon (SPB), while LMD has developed the measurement gondola. This concept has been validated in several test flights.

LATACUNGA 1998 campaign

Six STRATEOLE SPBs were released during the Latacunga campaign. The basic instruments in the gondolas were two temperature sensors, a pressure sensor, a GPS receiver and an ARGOS transmitter. Measurements were made every 12 minutes. Three flights lasted more than a few days :

    KIRUNA 2001 campaign

    Three STRATEOLE SPBs were flown during the Kiruna 2001 campaign. For security reasons balloons were destroyed when flying south 50N.
