The on-board attitude estimation represents a major task of the attitude and orbit determination and control subsystem as it is necessary to guarantee the spacecraft pointing accuracy as prescribed by the mission requirements. In a space mission each components requires a deep test campaign as well as the attitude estimation techniques where the Monte Carlo statistical approach represents the final step to fully validate the attitude determination algorithms. Motivated by this needs, a simulation tool suitable to develop, test and finally validate all the algorithms selected for the mission has been conceived and implemented in the ALMASat-EO context.
