Description of the Cansat missions
A little after the launching of our CanSat, at a given point of its descending orbit, a tiny capsule will be released ; this will contain a magnetometer which will carry out the necessary measurements while remaining tethered to the main body of our construction

Progress Report 1:
We have assembled both cansat kits, built an antenna for 430 MHz band and run several experiments regarding the tether cable' s durability. However our tiny sub-satellite and a cross-shape parachute still remain at the design stage. And as soon as our cansat is finalized it will need to be programmed and prepared for the launch campaign.

Progress Report 2:
We have assembled both CanSat kits so far, built an antenna for 430 MHz band and run several experiments regarding the tether cable’s durability. We have also designed and performed a test to measure our cross-shape parachute's drag force. Time is really pressing now so everything concerning our primary and secondary mission has to be finished as quickly as possible.

Progress Report 3:
Most of the tasks, tests and experiments have been carried out by the whole team during our meetings 2-3 times a week after school or in weekends. Due to the long distances between the places we live, some machinery works have been assigned to the team members who have access to power tools and suitable instruments. We have assembled both CanSat kits, built and tested an antenna for 430 MHz band and run several experiments regarding the tether cable' s durability. We have also designed and performed a test to measure our cross-shape parachute's drag force. Our final CanSat is based on the older one of the supplied kits as we were more familiar with it and we also needed its accelerometer. A servo motor has replaced the previously proposed step motor as it proved to be trouble free (no accidental micro-controller resets) and much easier to fit in place and handle.
