EPFL Space Situational Awareness Team
EPFL SSA Team
In view of the growing number of space debris in Earth orbit, as well as the increasingly frequent commissioning of satellites, it is becoming urgent to organise space traffic. Indeed, since orbiting objects travel at several tens of kilometres per second, the slightest collision results in considerable damage. This material damage is a source of high maintenance costs, but it also causes the appearance of new debris, which in turn increases the probability of collisions…
Under the impetus of the Laboratory of Astrophysics (LASTRO), the Space Situational Awareness (SSA) EPFL Team was founded in spring 2020. Its objective is to set up a catalogue containing important information on every object detectable in Earth orbit, in order to predict, and thus avoid, dramatic collisions. For LASTRO, in particular, this catalogue will facilitate the organization of observations. The catalogue will have to be updated automatically and in real time, and excel in terms of accuracy and reliability. The ambitions of the team are thus realized in the medium and long term, and meet a concrete need for sustainable development.
In practice, the team intends first of all to work on a large classified database and develop software capable of processing new images and composing the catalogue using them. At this stage, the team will then be able to start developing the image acquisition device best suited to its needs. The image acquisition system and associated software should eventually form a complete system for building and publishing the catalogue, benefiting space organizations and observatories.
The SSA EPFL Team, which will consist of about ten students in July 2020, is looking forward to welcoming new recruits. The team’s activities will certainly be of interest to any student with a passion for space development. On the other hand, students interested in the problems of image classification using Machine Learning, or in numerical simulations, will also find some of the team’s activities attractive. Engineering students may be interested in the development of the physical image acquisition system. The different sub-projects of this interdisciplinary project are presented on the team’s website :
