The uplink analytical simulation scenario of atmospheric turbulence-induced beam deviation can give the insight needed to understand and create the mitigation techniques that could support novel applications in the fields of free-space optical communications (FSOC) and the generation of laser guide stars. One of the significant challenges that causes wandering and fading of the beam from the receiver aperture is beam deviation. In this study, two uplink numerical modelling scenarios for low-earth orbit (LEO) and geostationary (GEO) satellites will be investigated and discussed. The work seeks to visualize the effective parameters and analytically simulate atmospheric optical propagation, especially for the wandering effect, which can give concrete milestones for developing a new scientific investigation era and deeper insight into the system’s theoretical demonstration of free-space optical communications.
