Abstract

This paper contains a review of technologies, theoretical studies, and experimental field trials for optical communications from and to High Altitude Platforms (HAPs). We discuss the pointing, acquisition, and tracking of laser terminals and describe how laser beams with narrow beam divergence can be used to transmit data at multi Gigabit/s. Investigating the influence of the atmosphere, background light and flight qualification requirements on system design, we explain why the data rates in free-space optical communications are still significantly below what is possible in today’s terrestrial fiber-based systems. Techniques like forward error correction, adaptive optics, and diversity reception are discussed. Such measures help to increase the data rate or link distance while keeping the bit error ratio and outage probability of the optical HAP communication system low
