A-DOT (Active Deployable Optical Telescope) is an innovative project aimed at developing a space telescope with deployable optics. This cutting-edge technology will be housed in a shoebox-sized spacecraft known as a 6U CubeSat. CubeSats are small satellites composed of standard-cubes, with a standard “U" measuring 10cm per side. These compact, cost-effective satellites utilise standardised parts, making them an attractive option for various space missions.

A-DOT can be configured in different ways so that can be used for both Earth observation and astronomy research. Helping to track flooding, model climate change or monitor agriculture; it also aims to look outwards to observe planets and moons in our Solar System or measure star brightness.

A-DOT's deployable aperture, being bigger than a fixed aperture, can collect more light. A larger aperture also improves image resolution, thereby enabling more detailed observations. This feature also allows for smaller and cheaper satellites, making advanced space observation more accessible.

A-DOT features a novel deployment mechanism, which includes mirrors that can be adjusted and aligned in space. Additionally, it will employ a fully automated on-board algorithm – including machine learning – for fine alignment, ensuring precise and accurate observations.

At UK ATC, we are developing the A-DOT payload, which includes the telescope, detector and control software. Our current efforts are focused on creating a comprehensive end-to-end optical model; testing the precision of the deployable mirrors; advancing the active optics control systems and their electronics and designing the telescopic secondary mirror assembly. This multidisciplinary project combines expertise from various fields –electronics, optics, active optics, mechanical and systems engineering – as well as scientific research, with the goal of delivering a fully operational, science-ready system to the community.
