Acquisition Time in Laser Inter-Satellite Link Under Satellite Vibrations

Pointing, acquisition, and tracking (PAT) is a major technical challenge of laser inter-satellite links (ISLs). For the fast establishment link maximization communication time, it importance to minimize acquisition time. Satellite vibrations affect PAT procedure adversely, thus serve increase In this paper, we investigate through theoretical analysis average time ISLs in presence satellite vibrations. The analytic expression about taken from beginning spiral scan beam provided pointing errors caused by We also derive optimum divergence angle for analyses are validated Monte-Carlo computer simulations proof-of-concept experiment. results show that can be minimized adjusting adaptively conditions.
