Abstract

The paper presents the general interplay of coarse and fine tracking sub systems for an optical intersatellite link terminal. It briefly describes the hardware items that were designed by the Contraves Space led team to realise the required pointing, acquisition and tracking (PAT) functionality, especially in view of a commercial use of the terminals. Additionally, the control concept is outlined and test results are presented that were obtained during PAT sub system tests, used to verify the acquisition algorithms and the closed loop tracking performance.
