CASTELLANOS, Cesar A  e  APARICIO PICO, Lilia Edith. Design and simulation of an attitude determination system based on the Extended Kalman Filter for Cube-Sat Colombia I. Rev.fac.ing.univ. Antioquia [online]. 2014, n.70, pp.146-154. ISSN 0120-6230.

The purpose of this document is to describe the design and simulation of an attitude determination system (ADS) for the CubeSat Colombia I picosatellite, based on an extended Kalman filter EKF [1,2]. In this development the propagation of the State of the system has been implemented through a Runge-Kutta procedure instead of traditional State Transition matrix method, improving predictions from the EKF filter without making direct measurements of angular velocity, it was obtained a reduced prediction time by incorporating a deterministic algorithm (the TRIAD algorithm) within the EKF. The results validated through simulation are those shown in this article.
