Scientific paper
It is shown that the dynamical requirements determined for a CO2 lasercom system can be met with the fine pointing assembly (FPA) and the coarse pointing assembly (CPA) described here. The implemented control loops and the corresponding control logic provide the PAT subsystem with a high bandwidth and a short transition time from the acquisition to the tracking mode. It is demonstrated that the maximum angular rate of the LOS in connection with the maximum slew rate of the CPA and the magnification factor of the telescope determine the area around the singular point which the FPA must be able to cover.
