In this paper, we study the performance of unmanned aerial vehicle (UAV)-based free-space optical (FSO) systems over atmospheric turbulence channels considering the pointing misalignment and UAV hovering. The Gamma-Gamma distribution is used for modeling the turbulence-induced fading and the Gaussian beam is assumed for laser beam between two UAVs at the low and high altitudes. A closed-form expression for the symbol error probability is derived and validated by Monte-Carlo simulations. The selected results show the impact of some key factors such as UAV position and beam-waist on the system performance so that the practical system parameters can be determined.
