Spacecraft Attitude Coordination Control Strategy for Rapid Construction of Laser Link

A novel spacecraft attitude coordination control strategy for rapid construction of laser link in the gravitational wave detection mission was proposed in this paper. Uncertainty cone caused by the orbital navigation error would be reduced by adjusting the installation angle between the Star Tracker and Telescope with the method. Therefore, the number of laser scans will be reduced and the laser link build time will be shortened. Numerical results are presented to quantify the number of laser scans and to demonstrate the effectiveness of the control strategy.
