The OGMS-SA project (OutGassing Material Study by Spectroscopy Analysis) was born in 2013 and was initially an in-orbit demonstrator in the Belgian QB50 project. It is scheduled to launch in late 2020 or early 2021.


The goals of OGMS-SA are to:

• Demonstrate a new sensor called CRDS (Cavity Ring-Down Spectrometer) in orbit
• Study degradation of materials exposed to solar radiation (UV and heat) and analyse trace gases (pollution) in low Earth orbit
• Get students engaged in a space project covering the three key disciplines of science, engineering and management


OGMS-SA is a 3U cubesat built by students with international participation from Cape Peninsula University of Technology (CPUT, South Africa) and Virginia Space Grant Consortium (VSGC, United States), which will both be providing their UHF-VHF ground stations. More than 80 students have already worked on the project.


Exploded view of OGMS-SA.

A specific feature of OGMS-SA is its structure built by additive manufacturing with a plastic called Windform XT 2.0 (approved by NASA and ESA for use in space). This structure is then coated withmetal (copper, nickel and chrome).

The ground segment will consist of a control centre, a mission centre and a VHF/UHF antenna at Paris Est Créteil University.
