Next generation of C-band SAR utilising Digital Beam Forming (DBF) techniques allow significant coverage improvements at high resolution as confirmed in several ESA studies in the field. Several TRP studies in the field of Digital Beam Forming (DBF) have confirmed the feasibility to achieve 400km swath width at 5m x 5m resolution, while Sentinel-1 achieves currently 80km at 5m x 5m resolution. The DBF technological elements are currently under development in the GSTP activity ?Integrated Tile Demonstrator (ITD)? based on extended Sentinel 1 requirements.

The activity aims to develop techniques (e.g. high sensitivity algorithms, data wipe off for Galileo, optimal data plus pilot combinations etc.) in order to enhance the capability of mass market receivers taking into account their typical resources constraints (limited power, memory, open loop platform etc...). The activity shall investigate the application of these techniques for phase and code tracking down to the detailed design of the techniques for different type of usage and in different type of environment.

The activity was able to develop and improve technologies and processes (such as polishing) that will enable manufacture and production of lightweight, highly aspherical, metallic optical mirrors with the accurate surface shape and low roughness needed for high performance optical systems, such as telescopes and high-resolution spectrometers.

The works performed by Savoir-Faire, Savoir-IMA and the related industrial activities have not investigated yet the particular impact of a multicore in the hardware topology on the On-Board Software Reference Architecture. The architectural principles are indeed modular enough to minimize the impacts of the use of a new type of processors. Using a multicore (also in the scope of IMA) in this scope is feasible. But specific aspects need to be investigated:

    X-ray emission plays an important role in characterising and locating energetic eruptions on the surface of the Sun and as a result there is a long history of X-ray imagers and radiometers. X-ray imagers include the SXI imager on recent GOES satellites and the SXT instrument onboard Yohkoh. As an alternative to imagers, whole-disk monitors provide typically higher time resolution a simpler means of capturing the onset and evolution of solar events, and so providing alerts. Monitors (or radiometers) include those on RHESSI and the XRS instrument on GOES satellites.

    Test automation is now integrated within the life cycle activities for a number of Ground Segment products. The current approach for automated testing relies on two main strategies:
    • Use exposed interfaces to drive the system under test. The most commonly used interfaces are APIs and the CORBA interfaces to the visualization layer.
    • Use the user interface (GUI) to drive the system under test

    Artificial intelligence will allow vast quantities of earth observation data to be analyzed. Image compression can both provide a performance boost and make systems more economical. However, most high-performance compression methods have been tuned to the human eye, rather than developed for machine vision, generating artefacts that although invisible limit the performance of advanced algorithms. Compression targeting AI and high radiometric accuracy applications is needed.

    An activity with GSTP Element 1 and Greece has developed a generic alarm management system. Currently, spacecraft operation teams are usually notified of non-nominal conditions when specific system parameters exceed preset threshold values, alerts that do not offer operators a deeper insight into a system’s condition. The Advanced Alarm Management System will: Enhance alarm generation and notification system through advanced processing of the data using industrial grade Complex Event Processing (CEP) technologies.

    Many types of science missions focus on Solar System targets with harsh thermal environments, such as Mars, the Moon, asteroids, comets, and other bodies at the fringes of the Solar System. Traditional spacecraft avionics rely on the storage of electrical energy in electrochemical systems (typically secondary batteries) for covering peak energy demands and periods where no electrical energy is generated (Lunar/Martian/cometary night, etc.).

    Developing a high-performance, but low cost satellite with very high resolution products would open the Earth Observation market to a new audience, creating a path for new applications and ultimately encouraging competitiveness.

    These products are currently not often covered by the space industry and access is very limited. As such a new low cost satellite, with turnkey technology could open the market considerably. A new activity, with GSTP Element 2 and Spain, has developed a spacecraft to do just that.
