The Coarse Pointing Assembly (CPA) is a two axis beam deflecting system which when integrated with the telescope provides a periscope form of coarse pointing. The CPA will provide the large angular view ranges of the Field of Regard (FOR) and provide the low bandwidth means of control of the OISL Terminal line of sight.

Description in English
The aim of the project is to develop, manufacture and test a functional sample of a Coarse Pointing Assembly for optical inter-satellite communication. The mechanism is meant to be a part of new product line aiming at satellite constellations. The important requirement of the design activities is the acceptable price which is expected to be dramatically lower than for traditional space mechanisms. That requirement is dictating a use of parts, components, manufacturing processes that are not traditionally used in space. The technical risk related to use of non-space items is to be minimized by involving detailed analyses supported by vast test campaign.
