Abstract—Free space optical wireless communication plays an important role in satellite communications. In the future, inter-satellite optical wireless communication (IsOWC) systems will be one of the most important applications for connecting one satellite to another in the same orbit or different orbits. IsOWC systems offer high data rates, minimum delay, minimum signal attenuation, small size, fewer power requirements and narrow beam divergence compared with that of present microwave satellite communication systems. Here, a low earth orbit (LEO) satellite constellation is modelled, and an IsOWC system channel is analysed for different modulation types, wavelengths, transmitter output powers, optical apertures and link distances. OptiSystem 7.0 and Matlab were used for modelling and simulation.
