Passive Thermal Design of a Thermal Infrared Telescope

The Deployable Space Telescope (DST) project aims to reduce the stowed volume compared to other Earth observation satellites with a similar resolution. The DST demonstrator functions in the thermal infrared (TIR) domain, which imposes stringent thermal requirements on the detector. The detector must be cooled to 150 K, and the instrument box to...

Design, Construction and Validation of a secondary mirror deployment mechanism for a thermal infrared space telescope

The miniaturization of satellites throughout the decades is mostly contributed by the advancement in electronics and technology. Volume and mass of a satellite are factors of the launch costs. The Deployable Space Telescope (DST) program<br/>aims to reduce the stowed volume of the telescope and subsequently reduce the costs.<br/>Telescopes have...

Implementation of an automated Systems Engineering Toolset in the DST project

In the DST project, a deployable space telescope is designed for the thermal infrared spectrum. For this project, a new Systems Engineering (SE) approach was needed, since the SE was outdated and the project worked in silos. Important goals for the SE approach were that it was easy to use and minimizes the workload by automating as much as...
