ITURRAMASAT 2019 OBJECTIVES
The project has three main objectives, the first of a technical nature, the second and third ones of a scientific nature:
1) To simulate an exploratory space mission to another planet
First, we will measure some physical parameters (pressure, Temperature, accelerations, inclinations, GPS coordinates, time) and calculate other ones (height, speed) from measured ones. Then, they will be transmitted to an intermediate system and retransmitted from the intermediate system to Earth. In addition, this transmission will be developed under the condition of sending and receiving the maximum amount of data, and the retransmission will be able to be followed in real time on our website. The communication will be bidirectional, we will be able to interact from Earth with our CanSat, switch on a buzzer, turn on LEDs, open the second parachute housed inside the CanSat, etc. from our website.
After the launch, thanks to these data we will:
- Obtain or draw graphs regarding time and height of the previous data.
- Compare different measurement forms for temperature, height and acceleration.
- Represent in 3D our CanSat trajectory.
- Obtain an approximation of the wind speeds profile at the launch site.
2) To study the uRAD Arduino version of Anteral for detection of Earth from air, to determine the altitude in unknown atmospheres in space missions. To train a neuronal network which, from the heights taken with the barometric sensor, will allow us interpreting the data taken by the radar and determining the reliability of them.
3) To determine and compare the drag coefficients for semi-spherical parachutes with central hole of radius 1/4 and 1/3 of the radius of the sphere. We will use two different parachutes: the first one will detach when the second one opens, from constant speed instants we will determine two geometries’ drag coefficients (CW) and compare them for similar speeds.
