6/11/2023 0 Comments End space free alignment![]() Current challenges and future research directions are addressed and integrated by combining different ideas.įree-space optical (FSO) links are competitive wireless links offering high data rate, security and low system complexity. Also, the various approaches are discussed and compared for precise alignment between the ground station and its associated UAV, highlighting their advantages and limitations. ![]() This paper addresses coarse to fine pointing, acquisition, and tracking (PAT) approaches and the recently developed tracking approaches to establish a reliable link for communication. So, tracking mechanisms are of vital importance when considering UAV-based FSO communication systems. However, FSO is a narrow line of sight (LoS) technology that is highly affected by the misalignment between the transmitter and receiver. Consequently, current developments in UAVs have provided new horizons for establishing UAV-based FSO links. One of the major issues in communication with UAVs is the enormous amount of data generated by UAVs that requires a high data rate link, making the free space optics (FSO) communication, with very high bandwidth, an appropriate choice. Miscuing UAVs can lead to potential threats as they are considered an essential part of national security. ![]() The challenge of tracking unmanned aerial vehicles (UAVs) is arising out of increasing their market and spread usage in many applications.
