Performance Assessment of a Vibration Isolator for Inter-Satellite Laser Communications.

Journal of the Japan Society for Aeronautical and Space Sciences, 1999
Inter-satellite communication instruments require a very-high pointing stability and accuracy, for example, on the order of one micro-radian. This is reachable by means of controlling the employed FPM (Fine Pointing Mechanism) in a wide frequency range.

A compact and lightweight two-dimensional gimbal for inter-satellite laser communication applications

Optics Express, 2019
To achieve precise alignment, tracking and pointing, inter-satellite laser communication generally requires a two-dimensional gimbal. To satisfy the requirements of space applications, the gimbal needs to be high-precision and as small as possible. To meet this need, we designed a small and lightweight gimbal assembly.
