COLOGNE, Germany (DLR PR) — Reliable and powerful computers play a central role in space travel: computer systems in satellites, for example, enable demanding earth observation missions. The German Aerospace Center (DLR) is developing a new computer architecture that is intended to give the so-called on-board computers (OBC) more power and also enable them to repair themselves. Distributed heterogeneous OBCs are being developed in the ScOSA (Scalable On-Board Computing for Space Avionics) flight experiment project. You have different computing nodes connected as a network.
COLOGNE, Germany (DLR PR) — The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the US National Aeronautics and Space Administration (NASA) are collaborating on a software library that will make it possible to use today’s quantum computers to explore the potential of quantum computing to solve real-world aerospace application problems.
OBERPFAFFENHOFEN, Germany (DLR PR) — There are no easy comparisons to show how accurate the clocks on the Galileo satellites are. Is it a matter of fractions of seconds, or of milliseconds, perhaps? That is far too imprecise. The Galileo system uses atomic clocks that are accurate to the nanosecond. One nanosecond is a billionth of one second.
