“…This survey is The first theoretical study on optical uplink transmission from ground-to-satellite has been studied by Fried in 1967 [16]. Few years later, an uplink transmission using ground-based continuous-wave (CW) argon laser towards geodetic Earth orbiting satellite-II (GEOS-II) was demonstrated in [17]. Thereafter, various theoretical studies were suggested [14], [18]- [20] and successful experiments [21]- [23] were performed to investigate optical ground-to-satellite and inter-satellite communications.…”

Abstract-In recent years, free space optical (FSO) communication has gained significant importance owing to its unique features: large bandwidth, license free spectrum, high data rate, easy and quick deployability, less power and low mass requirements. FSO communication uses optical carrier in the near infrared (IR) band to establish either terrestrial links within the Earth's atmosphere or inter-satellite/deep space links or ground-to-satellite/satellite-to-ground links. It also finds its applications in remote sensing, radio astronomy, military, disaster recovery, last mile access, backhaul for wireless cellular networks and many more. However, despite of great potential of FSO communication, its performance is limited by the adverse effects (viz., absorption, scattering and turbulence) of the atmospheric channel. Out of these three effects, the atmospheric turbulence is a major challenge that may lead to serious degradation in the bit error rate (BER) performance of the system and make the communication link infeasible. This paper presents a comprehensive survey on various challenges faced by FSO communication system for ground-to-satellite/satellite-to-ground and inter-satellite links. It also provide details of various performance mitigation techniques in order to have high link availability and reliability. The first part of the paper will focus on various types of impairments that pose a serious challenge to the performance of optical communication system for ground-to-satellite/satellite-to-ground and inter-satellite links. The latter part of the paper will provide the reader with an exhaustive review of various techniques both at physical layer as well as at the other layers (link, network or transport layer) to combat the adverse effects of the atmosphere. It also uniquely presents a recently developed technique using orbital angular momentum for utilizing the high capacity advantage of optical carrier in case of space-based and near-Earth optical communication links. This survey provides the reader with comprehensive details on the use of space-based optical backhaul links in order to provide high capacity and low cost backhaul solutions.

“…As the turbulence is weak or/and the propagation path length is not large enough, which is called weak fluctuations regime, the scintillation index is proportional to the Rytov variance cr12 = AC,k716L"6 (2) where A is a constant I .23 for plane waves case, 0.5 for spherical waves case, respectively; C2 is the index-of-refraction structure parameter for denoting strength of atmospheric turbulence; k is the wave number of optical wave of the propagating laser beam and it is defined as 2ir/2, and A is laser wavelength; and L is the propagation path length between transmitter and receiver. The scintillation index will increase with increasing values ofRytov variance until it reaches a maximum value greater than unity.…”

A new heuristic optical scintillation model developed recently is viewed and it is a available method in investigation on laser beams propagation in turbulent atmosphere. The irradiance scintillation is treated as a modulation of small scale scintillation by large scale scintillation as laser beams propagation in turbulent atmosphere, the irradiance scintillation is investigated for uplink propagation at various receiving heights and zenith angles for different atmospheric turbulence model. The influences of receiving height and zenith angle on the irradiance scintillation is analyzed for different atmospheric turbulence model, and the conclusions deduced are useful for farther future researches.

“…8 Experimental results of nighttime scintillation measurements at a satellite from a ground-based laser transmitter have been reported by Minott. 9 A detector aboard the GEOS-11 satellite at an altitude of 1250 km was illuminated by a 0.488 jrn cw argon laser. Log-amplitude variance, probability distributions, and scintillation frequency distributions were derived from the data.…”
