Opis:: The paper presents a method of calculation of position deviations from a theoretical, nominally rectilinear trajectory for a SAR imaging system installed on board of UAV. The UAV on-board system consists of a radar sensor, an antenna system, a SAR processor and a navigation system. The main task of the navigation part is to determine the vector of differences between the theoretical and the measured trajectories of UAV center of gravity. The paper includes chosen results of experiments obtained during ground and flight tests.

Opis:: The paper presents methods of on-line and off-line estimation of UAV position on the basis of measurements from its integrated navigation system. The navigation system installed on board UAV contains an INS and a GNSS receiver. The UAV position, as well as its velocity and orientation are estimated with the use of smoothing algorithms. For off-line estimation, a fixed-interval smoothing algorithm has been applied. On-line estimation has been accomplished with the use of a fixed-lag smoothing algorithm. The paper includes chosen results of simulations demonstrating improvements of accuracy of UAV position estimation with the use of smoothing algorithms in comparison with the use of a Kalman filter.

Opis:: The paper presents a project of an integrated positioning system composed of a dead reckoning unit (DR), and a GPS receiver. The DR subsystem includes an Attitude and Heading Reference System (AHRS) and an odometer. The data from DR and GPS are jointly processed via an algorithm of linearized complementary Kalman filter. The paper shortly introduces an idea of relative and absolute navigation. Next, it presents state-space description of the AHRS/ODOMETER/GPS integrated system. a functional structure of the system and Kalman filtering algorithm are presented. At last, the authors outline an adopted methodology of testing of AHRS/ODOMETER/GPS integrated system. Chosen results of the tests, conducted with use of real navigation data, are included in the paper. The presented positioning system may find its application in land vehicles.
