2010 competition rules
1. The teams
The teams can be composed of three to ten high-school students, but a maximum of four students will be able to represent the school in the competition. The students should be assisted by a teacher or tutor who will be the point of contact between the students and the organisers. All participating students and teachers should hold the nationality of an ESA Member State or Co-operating State. Teams from Cooperating States should have the approval of their country’s ESA Delegation.
2. The CanSat missions
The missions and their requirements are designed to reflect various aspects of real space missions including telemetry, communications and autonomous operations.
Primary mission: telemetry
The students must build a CanSat and programme it to accomplish the obligatory primary mission, as follows:
After release and during descent, the CanSat shall measure the following parameters and transmit the data as telemetry once every second to the ground station: (i) Air temperature, (ii) Air pressure.
It must be possible for the team to analyse the data obtained and display it in graphs.
Secondary mission: free choice
The students must develop a secondary mission of their choice. They can be inspired by other real missions of satellites.
Below are some examples of secondary missions; however teams are free to choose or invent another mission that is not covered here, as long as it has some technological, investigative or innovative value:
a) Advanced Telemetry
After release and during descent, the CanSat measures and transmits additional telemetry to that required for the primary mission, for example: (i) Acceleration; (ii) GPS location; (iii) Radiation levels
b) Telecommand
During descent, commands are sent from the ground to the CanSat to perform an action, such as switching a sensor on and off, changing the frequency of measurements, etc.
c) Comeback
The CanSat navigates autonomously with a control mechanism such as a parafoil. The objective is for the CanSat to land as close as possible to a fixed target point on the ground after it has been released from the rocket. This mission is an advanced telemetry/telecommand mission - navigation data is exchanged between the CanSat and a ground station throughout the descent.
d) Landing System
For this mission, the team develops an alternative safe landing system for the CanSat, such as a bespoke parachute or airbag.
e) Planetary Probe
The CanSat simulates an exploration flight to a new planet, taking measurements on the ground after landing. Teams should define their exploration mission and identify the parameters necessary to accomplish it (e.g. pressure, temperature, samples of the terrain, humidity, etc.).
