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., Aquest treball conté l’anàlisi i les millores pel que fa als procediments de prova de nano satèl·lits d’actitud. Un sistema completament nou per mesurar velocitats angulars ha sigut dissenyat des de zero per aplicar-lo a les campanyes de proves de Cubesat. Aquest sis- tema ajudarà a seguir les rotacions del nano satel·lit en les diferents proves. Con `eixer la velocitat angular del nano satel·lit mentre es realitzen les proves és molt important, ja que permet calibrar els giroscopis així com establir unes condicions perfectes i conegudes al satèl·lit.

The thesis task is to implement the algorithm for the automatic extension link into a proper Dasa computer system in order to control a forwarder crane. The implemented code should be tested at the laboratory crane at Linneus University, Vaxjo.

The first step in this work of reconstruction of a theory of insect vision was to demonstrate that visual behaviour relies on scanning by self-motion and apparently involves measurement of angular velocities of contrasts moving across the eye. The next step was to demonstrate that parallax is also significant as a way of segmenting the visual scene into separate objects. There followed a series of experiments to rule out the existing theory that motion perception depends on autocorrelation, and at the same time an alternative theory was developed. The new theory assumes that at the level of the optic medulla there are numerous parallel channels on each visual axis, representing different neurons, all looking out for their specific combination of signals. The combinations are formed by positive, negative or no-change temporal contrasts at two adjacent visual axes at two successive times, forming 3(4) = 81 possible templates. Simulation of this highly parallel system shows that it can represent the moving image in a compact form that would be adequate to explain what is known for motion and form vision (but not colour vision) in insects. Form, like colour, would be seen as the ratio of numbers of responses of particular templates, in the same way that colours are seen as ratios of responses of receptors for different wavelengths.
