Liebe Studierende,

Welcome to Space Informatics!

This news contains important information such as the planned course structure, and how to remotely participate in the course's events.

Live Event:

We ask you to be present at the live event tomorrow, April 15 at 2pm, taking place in Zoom. You find the participation link in the Materials page in our dCMS.

Course Structure:

  • The lectures will mostly consist of recorded videos published in our dCMS. Whenever there are live lectures, they will be announced beforehand. Live lectures will be held in Zoom (and might or might not be recorded).
  • In addition, there will be live events on weekly Thursdays. There, the lecturers will briefly recap the covered materials and then offer you the possibility to ask questions and initiate discussions. We will use Zoom for this, too.
  • The default mode of operation for Thursdays after the live events are office hours. There, you can reach out to our tutors and get help with exercises and the projects.
  • Sometimes on Thursdays a tutorial will take place instead of office hours, to support you in studying the course contents. This is the place where various types of exercises are discussed. Both, the tutorials and office hours, will take place on Discord (link in Materials).
  • The course comprises four practical projects. Depending on the number of participants, you may be able to work on those in groups of two.
  • More details will be provided in the first introductory event on Thursday, April 15, at 2pm. You can find the participation link on the Materials page in the dCMS.

Physical Presence on Campus?

It will be possible to participate in the course (i.e. lectures and tutorials), and to be admitted to the final exam from remote. Note, however, that a written exam is at this point scheduled to take place on campus in the morning of August 2, 2021.

Feel free to contact us if you have any more questions.

Viele Grüße
    Euer Space Team

 

Space Informatics

A full semester module offered by the Chair of Dependable Systems and Software in summer 2021. It is worth 6 CP ECTS.

Context

Space technology is experiencing an unprecedented expansion in a what came to be known as the “new space”.

Massive mega-constellations comprised by thousands of satellites are being deployed in near-Earth orbit to provide world-wide Internet coverage and real-time imaging. This is enabled by lower cost and reusable rockets, which are launching more and cheaper spacecraft than ever before. Indeed, nanosatellite platforms of a few liters of volume are leveraging state-of-the-art miniaturization and electronics to pack capabilities traditionally exclusive of large satellites.

As a result, space is becoming more democratic, accessible to many academic actors, and open for start-ups to develop innovating commercial opportunities. Moreover, these advances spill to an increasing number of interplanetary robotic exploration missions, which in turn boost and motivate the possibility of manned missions to the Moon and Mars in the upcoming years.

Motivation

The amount and features of “new space” orbiting assets would simply fail to scale up without the proper support of automated, optimal, efficient, scalable, usable and robust computer sciences models and techniques combining both on-board as well as on-ground components.

Also, informatics can play a decisive role in facilitating a more sustainable space with accurate battery models, delay-tolerant data handling, trajectory optimization, debris collision avoidance, system verification and validation, on-line telemetry learning, among many others application opportunities.

Space is within reach, and future space professionals with this know-how at hand will become a valuable resource in the immediate future of space industry.

Space Informatics

The Space Informatics course is framed in the new space context and motivated on the hypothesis that computer sciences will play a central role in future near-Earth and interplanetary space missions. To this end, we present a curricula layout organized in three axes:

  1. the fundamentals of space environment ranging from orbital dynamics, to maneuvers, and interplanetary trajectories design,
  2. the specifics of space technology comprising energy handling, computers, communications and networking, and
  3. the application of informatics to 1. and 2. including linear and dynamic programming, model checking, and scheduling techniques.

These axes are accompanied by practical exercises and hand-on projects involving state-of-the-art software toolchains such as Systems Toolkit (STK). We will exploit scriptable interfaces (Python) to control STK and evaluate and optimize distributed space missions using informatics modelling tools such as Gurobi and Uppaal.
