N2 - Because of the complexity of stratosphere, HAPs might inevitably encounter relative motion with respect to the ground, which leads to variation of quality of service in the intended coverage area. Models for predicting the geographical coverage in the cases of shift horizontally and vertically, yaw, roll and pitch of HAP are presented in this work. And also the mechanisms of compensation based on steerable antennas in these cases are explored. The mechanism is then applied to a 127 cell architecture, with a cell cluster size of four. It can be seen from the simulation result that by employing the steerable antenna correction mechanism, the movement can be compensated to some degree in order to guarantee effective coverage of the service area.
