College Saint Pierre is back and ready for its 4th year participating in the Cansat competition with Student Team G-Mini. The competition is organized by the Walloon Region (SPW EER) and the Brussels-Capital Region (INNOVIRIS), with the support of ESERO Belgium. The goal of this competition is to send a 33cl can-shaped satellite to an altitude of about 1000 m to collect various data samples (atmospheric pressure, temperature, velocity, etc.) during its descent. All the teams have the same primary mission which involves collecting a basic dataset during the flight that lasts approximately 120 seconds. The competition is a 3-stage national selection process. 24 teams will earn their place on the launching rocket, the last selection stage. The winning team is selected to participate in the international European final.
In addition to the primary mission, each team has to create and decide on an achievable secondary mission. Last year, the mission was to observe how different shaped parachutes affect the descent of the Cansat, by making a parachute that would change its shape midflight. This year, we will be ejecting two “sub-cans” from our main can, which will enable us to have a larger surface area of data collection. Each sub-can will maintain a radio link both with the main can (which takes care of on-board storage) and with the ground station, for real-time data collection. This secondary mission is particularly challenging since 4 different “systems” will need to communicate flawlessly for the data collection to be optimal.
