Abstract
High Altitude Platform (HAP) must compensate for relative motion with respect to the ground because of the stratosphere complexity, which is important to guarantee Quality of Service(QoS) in intended coverage area. With analysis on HAP movement models for predicting the geographical coverage in the cases of shift horizontally and vertically, yaw, roll and pitch, the mechanisms of steerable antennas movement compensation are investigated. The mechanism is applied to a scenario of 127 cell architecture, with a cell cluster size of four. By the simulation results of Carrier to Interference Ratio (CIR), the steerable antenna movement compensation mechanism decrease influence of HAP movement and guarantee effective coverage of the service area.
