"We have been working closely with DLR on multiple missions over the years, inserting LEON3FT technology in both their spacecraft platforms and their experiments. The Eu:CROPIS mission is very interesting since it uses the GR712RC processor in both platform and payload, which is a first," said
These latest initiatives continue a longstanding collaboration between DLR and Cobham. The GR712RC processor was first launched on December, 2014 as part of the
DLR's Eu:CROPIS Earth-orbiting mini-satellite is studying the impact of low gravity and radiation on organisms in support of future long-duration manned space missions (life sciences). Launched last December from the
All the Command and Data Handling (CDH) functionality of Eu:CROPIS satellite has been integrated into a single warm-redundant unit. This CDH unit consists of a central, redundant on-board computer, which provides interfaces to sensors, actuators, communication equipment, the power control and distribution unit, and the payloads. It is composed of several subunits with dedicated functionality, representing an on-board computer (OBC). At its core are the CPU modules (CPM), based on the radiation-hardened GR712RC Dual-Core LEON3FT processor and which also contain different memories, the Interface Modules (IFM) which extend the CPM's functionality with external interfaces.
"The Command and Data Handling (CDH) unit utilizing the GR712RC processor is one of the core elements of the Eu:CROPIS compact satellite platform. We are very pleased with its reliability and performance, as it is the key element for handling data on-board the spacecraft and thus enables this unique space mission with its biological-, radiation-, and technological experiments. The system is performing nominally for almost one year now providing simulated gravitational environments equivalent to Mars and Moon gravity", said Olaf Eßmann, Eu:CROPIS project management, DLR.
The SCalable On-BoaRd Computing Experiment (SCORE) is a technology demonstrator payload for next generation on-board computing in hardware and software and has been developed by the
"The GR712RC processor provides a dependable base for SCORE and allowed us to reuse parts of the software from our main on-board computer. So far, SCORE is successfully collecting data on commercial off-the-shelf (COTS) memory in-orbit performance and has supported the Eu:CROPIS mission by collecting images from 3 exterior cameras", said
PowerCell, a payload contribution from
RAMIS (Radiation Measurement in Space), a payload contribution by DLR, provides data on the radiation dose experienced by the organic payload. Additionally, it measures the intensity of radiation in the Van Allen radiation belts as the satellite moves through them.
"First results from the RAMIS detector on the exterior of the spacecraft clearly show the 'breathing' of the outer radiation belts - that is, the daily variation of the particle fluxes of the electrons within the belts - as well as the size of the South Atlantic Anomaly," said
Cobham's processor and software products are on display this week at Stand E40 at Space Tech Expo Europe. In addition more information can be found at www.cobham.com/Gaisler
