The flight (37 ko)

A perfect taking off, a regular trajectory, a smooth landing. But we had a strong gondola.

The bursting of the balloon (130 ko)

Wonderful pictures of a wonderful time.

Following and location (100 ko)

The location in real time was made possible thanks to the traditional radiogoniometry method and an APRS coupled with a balloon-based GPS.

Measures carried out during the flight (21 ko + 2 PDF files)

Variation in altitude according to the time and graph of inner and outer temperatures according to the altitude.

Recovery of the gondola (27ko)

A balloon release is considered perfect only after the recovery of the gondola. ln our case the owners of the gondola-carried equipment were rather pleased to know that the gondola had been found.

Lots of stations followed the flight, among them several SWL, equipped with APRS in receiving. We quote some testimonies.
