摘要: Two Adriatic bora events to the lee of the Dinaric Alps occurring in spring 2002 are studied using observations and numerical simulations. The key instrument was an aerosol backscatter lidar operated in a nadir-pointing mode on board the German Aerospace Center's (DLR) Falcon aircraft....
The two-axis gimbal follows the movement of the two-axis pointing device, keeping the two-axis pointing device from encountering its mechanical limits. In this manner, inertial pointing control is maintained in the near gimbal zenith/nadir regime.NORMAN Walter W....

Adaptive controlParameters estimationLyapunov functionThe kinematics and dynamics of a nadir-pointing spacecraft with rotational component are derived in the presence of both the parallel and angular misalignments. Based on the derived model, the nadir-pointing control problem is formulated and an ...
