We analyze night-time near-infrared (NIR) thermal emission images of the Venus surface obtained with the 1-μm channel of the Venus Monitoring Camera onboard Venus Express. Comparison with the results of the Magellan radar survey and the model NIR images of the Beta-Phoebe region show that the night-time VMC images provide reliable information on spatial variations of the NIR surface emission. In this...
The demand for high-performance on-board processing in space applications drastically increased because of the discrepancy between extreme high data volume and low downlink channel capacity. Furthermore in-flight reconfigurability and dynamic partial reconfiguration enhances space applications with re-programmable hardware and at run-time adaptive functionality. Therefore it is a maintenance and performance...
Dynamic reconfiguration enhances embedded system with at run-time adaptive functionality and is an improvement in terms of resource utilization and system adaptability. SRAM-based FPGAs provides a dynamic reconfigurable platform with high logic density. The requirements for such an embedded high flexible system based on FPGAs are robustness and reliability to prevent operation interrupts or even system...
Configurable system-on-chip (SoC) solutions based on state-of-the art FPGA have successfully demonstrated flexibility and reliability for scientific space applications like the Venus Express mission. Future high end payload applications (e.g. Solar Orbiter) demand high-performance on-board processing because of the discrepancy between extreme high data volume and low downlink channel capacity. Furthermore,...
The Venus Express mission will focus on a global investigation of the Venus atmosphere and plasma environment, while additionally measuring some surface properties from orbit. The instruments PFS and SPICAV inherited from the Mars Express mission and VIRTIS from Rosetta form a powerful spectrometric and spectro-imaging payload suite. Venus Monitoring Camera (VMC)—a miniature wide-angle camera with...
Data Processing Units (DPUs) in space application as a reconfigurable System-on-Chip solution (SoC) based on a FPGA have been already successfully demonstrated in the Venus Express mission, providing the capability of flexibility and reliability for system design. An enhanced reconfigurable System-on-Chip solution for future space missions also includes the ability to re-program hardware functions...
Individual data processing units (DPUs) are commonly used for operational control and specific data processing of scientific space instruments. To overcome the limitations of traditional rad-hard or fully commercial design approaches, a system-on-chip (SoC) solution based on state-of-the-art FPGA is introduced. This design has been successfully demonstrated in space on Venus express. From this, a...
