Abstract

Aquest projecte proposa el disseny i la creació d'un sistema de captura de dades per a una unitat de mesura inercial, per a la posterior integració d’aquestes per tal d’obtenir una descripció detallada en 6 graus de llibertat del moviment d’un cos. A partir d’aquesta informació serà possible analitzar d’una forma no invasiva l’actuació d’algun tipus de vehicle aeroespacial.


Aiming to obtain aerospace vehicle ight parameters and engine characteristics, a DCM and magnetometer fusion algorithm is introduced in addition to a Kalman lter, in order to estimate position, velocity and acceleration in the vertical axis. This strategy is tested in the case of a model rocket, and the drag coe cient and thrust curve are calculated. The attitude of the vehicle is also estimated with fewer outcomes. Finally, It is described how the system could be upgraded so that trajectory in 3D can be obtained and therefore a better knowledge of the ight parameters.
