CanSat AESS Challenge 2019

A CanSat is a small satellite the size of a can. Inside it has all the normal components that a satellite has, such as sensors, transmission, batteries, parachuting, etc.

The purpose of this CanSat is to record variables related to movement, altitude and temperature within its container, and for that it was made to participate in the IEEE AESS CanSat Innovation Challenge 2019.

This is a dervided project of the On Board Computer of the POA model rocket made by the ATL research hotbed at Universidad Distrital Francisco José de Caldas.

Materials

  • Arduino pro mini (5v)
  • GY-BME/P 280 (you have to change the I2C address)
  • MPU6050
  • Xbee S1 (with antenna)
  • Xbee explorer
  • 9V Battery

pbc cansat

Sensor data:

  • time since it is turned on
  • relative altitude
  • free fall state
  • temperature
  • atmosferic pressure
  • pitch
  • roll
  • yaw
  • acceleration in X
  • acceleration in Y
  • acceleration in Z

Information is captured every 500 ms.
