== What is CanSat? ==
 +
CanSat Contest simulates the fly of miniaturized satellites named CanSat (Can Satellite).     
   −
The Cansat Belgium running MicroPython
+
The CanSat is an autonomous devices enclosed within the volume of a soda can.
   −
on the Raspberry-Pi Pico is currently
+
The volume of a CanSat has the following characteristics: 66mm diameter, 115mm height for a mass of 350gr.
   −
under writing.
+
As the CanSat have small volume and are very affordable, the CanSat contest is great for learning more about space technologies.
   −
Please check the available page in the menu --->
+
The CanSats are deployed from a rocket (the launch vehicle) at a height of about 3000m depending on the competition (see all the details in the contest rules).
 +
 
 +
The CanSats are not orbited and are always deployed in the athmosphere. So they always comes back to the earth.
 +
 
 +
The CanSat volume cannot increase until the CanSat is deployed out of the rocket.
 +
 
 +
This means that external antenna is allowed only after the CanSat left the rocket.
 +
 
 +
A parachute (that increase the volume of the CanSat) is usually used to limit damages. The aim is to reuse the CanSat for several missions.
 +
 
 +
In Europe, the CanSat contest includes two missions:
 +
* Mission 1: mesure pressure and temperature and transmit data in real time.
 +
* Mission 2: free choice mission (using Intertial Measurement Unit, GPS, MPX differential pressure sensor, etc).

== Mission 1 ==
 +
The team must build a CanSat and program it to accomplish the primary (mandatory) mission, as follows:
 +
 
 +
After release and during descent,
 +
* the CanSat shall measure several parameters,
 +
* the data should be transmitted as telemetry information to the ground station.
 +
* the telemetry should, at least, be send once every second.
 +
 
 +
The following informations should be captured:
 +
* Air temperature
 +
* Air pressure
 +
 
 +
It must be possible for the team to analyse the data obtained (for example, make a calculation of altitude) and display it in graphs (for example, altitude vs. time and temperature vs. altitude).

Optional: Adding a GPS module to transmit the CanSat position with the telemetry data would ease to positioning when back on the earth.
