ARTEMIS micro-vibration environment prediction

Micro-vibration environment control is mandatory to satisfy the micro-vibration level requirements of the Optical Data Relay (ODR) payload, which is a part of the SILEX (Semiconductor Inter-satellite Link Experiment) programme. This optical payload element, embarked on ARTEMIS, must experience an induced vibration such that the optical inter-orbit link is not affected, i.e. a high degree of stability must be guaranteed when the pointing mechanisms are finding the link with the second optical terminal and when the link is achieved. The purpose of the present paper is to show the evaluation of the ARTEMIS micro-vibration environment and the verification of the compliance with the I/F requirement. This micro-vibration analysis upgrades the previous ones in which historical and prototype data of the disturbance sources were considered together with the former structural transfer functions of the SILEX payload coming from MMS and the uncoupled ARTEMIS structural transfer functions.
