Descripció del contingut i pla d'activitats:
1. Take part of the different test involving helmholtz coil.
2. Increase functionalities in the current software: 2.1. Fix
Arduino - MATLAB serial communication errors for example.
2.1.Orbital representation of the simulated satelite positions
3. Change language Code in order to increase visual capabilities.
For instance Go (language not decided yet).
4. Study, design and implementation of an angular speed sensor in
order to be able to measure the angular speed of the platform
inside the helmholtz coils.(To decide if vídeo sensor or
photodiode sensor or both if posible for backup).
 
Overview (resum en anglès):
This work contains the analysis and improvements regarding attitude nanosatellite testing
procedures. An utterly new system for measuring angular velocities has been designed
from scratch in order to be applied to Cubesat testing campaigns. This system will help to
track the rotations of the nanosatellite in the different tests. Knowing the angular velocity
of the nanosatellite while performing the tests is so important. It allows to calibrate the
gyroscopes as well as set a perfect and knows conditions to the satellite. Also, the measurements can be compared with the gyroscope angular velocityes obtained in order to
recalibrate the system if necesary. Furthermore, a new design for Helmholtz coils software
has been proposed using a user Interface in C++. This new software allows the user to
initialize the coils with the desired magnetic fields required for testing. Two main operating ways has been considered: Static and Dynamic orbit magnetic field generation. Both
systems can work altogether in order to check the attitude determination and control of
the nanosatellite during testing campaigns. Nanosatellite needs to perform testing before
its launch. Thus, the whole project avoids expensive risks which could doom the mission.
The results obtained in this work show that the angular tracking works as desired for the
testing purposes and the Helmholtz coils GUI simplifies a lot the testing process from the
user point of view.
