Instead of the standard parachute-attached Cansat, our satellite will detach a paraglider. The way it connects with the body of the can will be the following: six directional lines. Of these six, two will have at the end micro-servos, responsible for modifying its curvature through tension. This results in a remote management of the Cansat´s direction and speed. This will allow us to obtain and record footage for the live retransmission and 3D mapping, which will be explained later on.
The pilot will use a data transmission system for a remote control of the Cansat during its landing. This will be achieved by a low frequency transmitter/receptor, to avoid any interference with the camera´s live signal.
Regarding the sensors, the Cansat will incorporate an accelerometer chip, a gyroscope, and a compass. The main function of these devices will be to facilitate the pilot the control of the Cansat. All this will be complemented with a GPS to indicate its position. All the information will overlap (OSD) in the live retransmission of the incorporated camera. For security reasons, all the footage will also be storage in the Cansat for later use.
To ensure a safe landing, we have designed a landing device on the bottom section of the can. As we will be forced to subtract the lower portion of the satellite to make room for the camera’s objective, we are going to take advantage of this situation. Around the objective and without exceeding the original measures of the can we will place nails slightly longer than the objective. Between these nails and the inside of the can where all sensors and chips are placed, a thin surface of a soft and elastic material will be introduced. This way, we will obtain various benefits. Stability, along with ensuring the health of the inside of the can, when the Cansat Lands. At the same time, the shape of the nails will provide it with more aerodynamic potential.
As a precaution, three bands will be attached to the sides of the can, to act as a support when the can falls and make sure that the nails fall correctly and are able to anchor the can to the surface.
