             abstract = "This work presents the simulation of an angular velocity 
                         estimation system composed by four tetrahedrally arranged MEMS 
                         gyrometers. The timewise angular velocity of the sensors readings 
                         are transformed to tri-orthogonal measurement sets by a 
                         pseudo-inverse matrix. A Kalman Filter utilizes periodically 
                         received attitude data to estimate the sensors bias and also a new 
                         attitude. Also, the angular velocity readings are used to 
                         propagate the systems state until arrival of the next attitude 
                         information. The Kalman Filter estimation and propagation 
                         equations used in this process are presented in the paper. Also, a 
                         Monte Carlo simulation results are shown demonstrating the filters 
                         convergence. This procedure will be implemented in an attitude 
                         determination device that will be integrated as an experiment 
                         aboard ITASAT-1 university satellite.",
