The new generation of space grade component from AMD, the VERSAL ACAP, offers a significant increase in processing performance compared to current generation space grade FPGAs. The XQRVC1902 ACAP comes in a lidless 2197 pin BGA package with 0.92mm pitch. It can consume more than 100W, with a core voltage of 0.80V at currents up to more than 100A. The use of this component on a space qualified board brings many technical challenges. This paper will present some of those technical challenges and how Airbus Defence and space is solving them.

We present a payload dataprocessing unit for imaging payloads in New space earth observation missions. The system is based on a commercial-off-the-shelf (COTS) heterogeneous multiprocessing System-on-a-Chip (MPSoC). To increase the reliability beyond what is possible using only software mitigation techniques, a dual cold redundant configuration is chosen.

Synthetic Aperture Radar (SAR) dataprocessing evolving from level-0 raw data is complicated, especially in data decoding, manifesting in obtaining a well-focused SAR image. This paper is intended to present a complete MATLAB-based SAR dataprocessing tool, which helps the end-user to treat simply the steps of image generation. This paper would enrich the research community in the field of SAR processors, especially in the area of understanding, handling, and developing a SAR processor based on space packet protocol standard (STD 01) used in many SAR systems such as Sentinel-1, ERS-1, CubeL, JPSS-2, 3, and 4. Also, this work opens the door for researchers to decode other space packet protocol standards and even to create an algorithm based on fully understanding the image formation algorithm from its roots. Moreover, the work in this paper could be a stepping-stone for the beginner in the field of SAR signal processing to become familiarized with SAR image generation procedures. The level-0 raw data used in this paper is based on Sentinel 1 SAR satellite obtained from the europeanspace Agency Copernicus website, a free open-source for level-0 and level-1 data types. The MATLAB program allows users to compare their generated image with the level-1 single-look complex (S1-L1-SLC) image utilizing entropy, contrast, and sharpness image quality metrics. The results showed that the images produced by the proposed algorithm are comparable to Sentinel-1 level-1 SAR images for the same scene and achieved satisfactory accuracy under the requirements for image quality.

This paper presents the results of an ESA activity in the area of onboard data networks aiming at defining a deterministic protocol layer for spaceWire and spaceFibre networks. The main objective of the activity is the development of a global solution for determinism for spaceWire and spaceFibre that works primarily at network level (i.e. within routing switch devices), allowing therefore to build fully deterministic networks with both protocol-aware and legacy spaceWire/spaceFibre nodes. The work has been performed under the ESA study entitled "spaceWire Network Management Service Suite definition and validation".

The Radiation Tolerant Intelligent Memory Stack Flash (RTIMS FLASH) is a high density, user-friendly, off-the-shelf, radiation-protected NAND Flash *** memory module integrates a high-density NAND flash memory and a flash memory controller (FMC). The controller provides the module with full protection against SEL, SEFI and SEU. It also offers continuous logic sectors (no bad blocks) and high-value features such as wear leveling, memory self-test, internal registers for telemetry information. It is suitable as a small data recorder in space applications.
