| Abstract | Current systems such as: unmanned aerial vehicles-UAVs, satellites, aircrafts, automobiles, turbines, power controls and traffic controls are becoming increasingly complex and/or highly integrated as prescribed by the SAE-ARP-4754 Standard. Such systems and their control systems use many modes of operation and many forms of handling information to achieve high levels of performance and high levels of accuracy under changing environments and phases of their lifecycle. So, the adoption of solutions that favour lower costs, either for development or operation, considering both the hardware and the software in use is mandatory. Therefore, to improve the economic benefit for a certain application, the accuracy that certain classes of sensors might lack can be overcome by properly performed calibration. In this paper, the Discrete-Discrete Kalman Filter (DDKF) is used, firstly, for the calibration of a baroaltimeter of a UAV with the help of other more accurate sensors (e.g. GPS, IMU, etc.). Secondly, the calibration performed is verified, in the same fashion. The baroaltimeter is embedded in a semi-autonomous aerospace vehicle, which flight is comprised of two phases: captive (for the calibration task) and free (for the verification task). To accomplish the proposed goals, one must take into account: 1. the adopted filtering technique; 2. the boundary operational conditions and initial values for the system' mission; 3. the estimation of sensor parameters which affects the accuracy such as the random bias and the scale factor for the sensor in question. The formulation and equationing for the filter, and the sensor model are described, implemented computationally, and then tested for such a set of representative situations. The results obtained highlight: 1. the difficulties for tuning the KF parameters and conversions; 2. the KF accuracy in estimating true values of unknown parameters; 3. the usefulness of this technique in enhancing the performance of systems quick and accurately. | |||
