On the “3rd LEEM International CanSat Competition”, you may compete in any of these three different categories:

Come-back :

Come-back is a CanSat which must navigate by its own resources until stopping as near as possible of a target located on the launch field ground.

The main parameter of evaluation will be the closeness to the target, but it will be also assessed the device originality, subsystem design and navigation algorithm.

The navigation of CanSats within the Come-back category must be autonomous.

Teams are authorized to download the telemetry but it is strictly forbidden to send navigation data from the ground station.

The target to be approached by Come-back CanSats will be marked with a red circle the same day of the Competition.

Teams can get to the target before assembling the CanSat into the rocket or balloon, to get their own measurements of the target coordinates and/or upload them on their own CanSat. The organization won’t announce the target coordinates.

Telemetry :

This category has the aim to select the team who will develop the relevant subsystem for LEEM Sounding Rockets.

The CanSat should send real-time flight data to the team’s own ground station.

The CanSat must send at least the following data to the ground station:

1. Identify code of 4 bits

2. Barometric altitude

3. External Temperature

4. Acceleration (at least along the longitudinal axis of the CanSat)

5. GPS location

6. Logic level of 3 digital signals (CanSat must simulate it)

7. Sensing of two events:

1. Launch of the rocket

2. Parachute deployment

Device originality will be assessed together with the telemetry and whole subsystem design.

Telemetry can be a Air-CanSat and/or Land-CanSat as the next videos from two teams of the 1st International CanSat Competition We CanSat Team on the left side and E.T.S.E.- CanSat

on the right side.

Planetary Probe and Scientific Experimentation :

Planetary Probe is a new category which was included in the “2nd LEEM International CanSat Competition”, as you may implement all the subsystems needed to measure whatever you consider relevant to know from a new planet on the first exploration flight.

This category will simulate an exploration flight to a new planet. Your CanSat will be launched to… “Planet Ayllon”.

Teams must define an exploration mission to an unknown planet like on a real Space exploration mission. All the parameters necessary to accomplish the mission ( pressure, temperature, pictures, samples of the terrain, humidity…) should be stated on the CDR documentation, explaining the reasons that led to its selection.

Scientific Experimentation is open for those teams who want to test a certain subsystem, aiming at the design of a future CanSat, or performing a scientific experiment of diverse nature. For all CanSats competing in this free category the following parameters will be assessed: success in achieving the objectives, originality, design and scientific relevance of the measurements made.

The CanSat will be launched only if it is able to accomplish at least 80% of the proposed objectives, stated in the design document, CDR (Critical Design Review).

Additional Info:

  • Teams should state the chosen category in which they want to participate when registering on the Competition.
  • Each CanSat will be launched by a rocket
