Space Mission Operations – Designing for the Future
As the computational power available both on Earth and on spacecrafts is growing, new ways of operating space missions can be implemented. The European Space Operations Centre (ESOC) in Darmstadt (D) is working towards that goal by developing new procedures and innovative software applications, continuously enhancing Europe’s capabilities and efficiency in space operations.
OPS-SAT is a small spacecraft designed by ESA CDF to provide a platform for in-orbit validation of these new concepts developed by ESOC. OPS-SAT will carry a number of experiments that will require a combination of changes to on-board and ground-software and will test methods for handling satellite data and operational processes that may be of use on other ESA missions. The focus of the mission design will be to implement software on off-the-shelf hardware. It will be very flexible, allowing ESOC experimenters to change every aspect of the on-board software in much the same way as one installs and changes operating systems and applications on a home PC. This means experiments that are not even imagined at launch can fly. The main experiments baselined are focused on testing the robustness of the new operation procedures and software applications along with high speed telecommunications. A four kilograms CubeSat form-factor was chosen to allow a fast and cost effective development cycle, equipped primarily with commercial off-the-shelf components.
