abstract = {In this paper, a design summary about the de- velopment of an unmanned aerial vehicle (UAV) highlighting strategic applications and possibilities is presented. The UAV is an helicopter of the quadrotor type. The discussion is focused in the kalman filter for attitude and position estimation, along with algorithms for camera stabilization and tracking of a point of interest. Flight test results show that the quadrotor is able to perform autonomous flight with the implemented Kalman filter, as well as to achieve a satisfying camera stabilization. The algorithms make possible to perform reasonably precise missions without investing in more expensive hardware, using a low cost platform. Here, an application concerning the reconnaissance of an area along a trajectory pointing for a target is discribed. However, the platform can be integrated in applications of major complexity.},

abstract = {Stabilized platforms are widely used in diverse engineering applications, such as robotics, telecommunications, being also frequently applied to military or defense systems. In this work, platform stabilization is performed using measurements of only two gyroscopic sensors. In this case, some can not be measured. Hence, compensation is achieved only under certain restrictions on the host vehicle motions. A sensitivity analysis is presented to quantify stabilization precision when these restrictions are not satisfied. Experimental results obtained in a platform whose movementes are similar to those of a vehicle are presented. Real data obtained by an instrumented vehicle moving along a typical path are used in simulation to evaluate stabilization precision in real operational conditions.},
