(a) The azimuth angle α over the flight time. (b) The deflection angle of transmitted photons. (c) The drifted offset of the beam, which reaches to the ground station. The speed of airborne is 0.7 Ma, the relative flying height is 10 km and the shortes thorizon distance between the aircraft and the ground station is 10 km
