Activities - Operation ARISS 2012

The technical Balloon Project of the Electronics Students

A school that participates in the ARISS program must incorporate in  their school program issues related to space. In this case, a technical  project had to be developed and built by students of the Education  Center of the Air Force Base Payerne (Switzerland).

The project named "HEIDI" had value of diploma project. The students had  to develop and build a payload for a stratospheric weather balloon with  a video camera, a transmitter in the range of 13 cm waves for  transmitting live images during the flight, a HD video camera with  memory onboard storage, various meteorological sensors, a GPS receiver  with a APRS-transmitter to track the trajectory of the balloon and its  payload, and finally - probably a world first for weather balloons - a  device for measuring temperature inside the balloon with data  transmission.

The project was a real technical challenge for the students. E.g. the  total weight of the balloon payload was limited to 2 kg, and electronic  and optical modules must operate in a wide range of temperatures, from  ambient temperatures at departure up to -60 °C at the border of the  stratosphere.

The main test with Electronic modules and the balloon took place as of  Thursday  March 1st, 2012. All the tests were successfully.

The learners lived the crowning of their work with the launch of the probe on March 15, 2012, at 13:57. After 2:45 the probe had reached its highest point at an altitude of 32,152 m and a speed of 39 km / h near the Lac Noir.
