Pointing Mirror Technology for Atmospheric Imaging Mission of Northern Regions ( AIM -North) — The project aims to develop a pointing mirror subsystem with the form, fit, and function of the future AIM -North mission. The goal of this mission is to measure the air quality and the concentration of greenhouse gases over the high latitudes using various instruments placed on a Highly Elliptical Orbit. While many Earth observation instruments carry a scanning mirror, the mechanism of AIM -North requires a particularly fine accuracy because of the high altitude of the satellite and the size of its mirror. This project will serve the development of instruments with a need to point over large angular range in both axis and stabilise tracking over cloud free region to maximise operating efficiencies.
