→ GSTP ACTiviTieS iniTiATeD in 2011 During 2011 81 activities were initiated under the frame of the GSTP. Highlights are presented. With the participation of Switzerland, France and Norway > Next Generation Radiation Monitor device With the participation of of Belgium, United Kingdom, Austria, Czech Republic, Italy, Netherlands, Germany and France With the participation of Germany, France, Luxemburg and Czech Republic > 8 channel ADS-B receiver which is the baseline for the IOD space design. 10 | GSTP Annual Report 2011 next Generation radiation monitor (nGrm) Spacecrafts are exposed to a complex radiation environment which is highly variable and at times very strong. Some space system failures and disturbances in recent years have been concluded to be due to radiationinduced malfunction of critical electronic parts. The aim of the activity is to make the necessary developments to create a general-purpose standard low-mass device suitable for most space radiation environments and with capabilities beyond those presently available. The NGRM instrument will provide measurements of the energy spectra and temporal variations of energetic protons and electrons encountered in space, with some additional sensitivity to ions. It is a follow-on and improvement to the previous ESA Standard Radiation Environment Monitor (SREM) project.. Decision Support and real Time earth observation Data management (DreAm) This technology development project will address the architecture and interfaces of the Payload Data Ground Segment needed to streamline the feasibility analysis, planning, ordering and access to ESA and third party missions Earth Observation (EO) products for two European institutions: the European Maritime Safety Agency (EMSA) and the European Union Satellite Centre (EUSC) . The project aims to support all the issues which arise when a decision process on the side of the user, needs to exploit information based on EO data from multiple missions including high resolution commercial optical ones. The project will as well identify and collect desirable requirements over sensor, missions and data provision such as additional radar data for EMSA and in particular optical high resolution data for EUSC. Finally the project will demonstrate possible interfaces and components within the multi mission ground segment infrastructure in support to end-to-end scenarios. Space based ADS-B Payload Development for Air Traffic Surveillance Automatic Dependent Surveillance Broadcast (ADS-B) are signals broadcasted by an aircraft on a regular basis at low L-band frequencies with a power of up to several hundred Watts. The signal includes flight related information such as position, speed, flight number and direction. Compared to a radar, the ADS-B offers more precision and additional services, such as weather and traffic information. This information is also available in areas not covered by radar, for example over oceanic airspace. The goal is to develop a space-based ADS-B receiving system and to demonstrate its functionality under representative space environmental conditions in orbit, compliant to requirements defined for spacecraft units and experimental payloads. The ADS-B IOD payload will consist of two main subsystems: a dedicated antenna and a receiver unit.
non-Conventional Carbon nanotube Skeleton reinforced Composites follow on (nACo2) NACO2 aims at manufacturing and characterising unambiguously the most promising materials identified within NACO (2007-2010). The main objective of NACO2 is to scale-up the material developments and thereby increase the technology maturity for Carbon Nanotube (CNT) skeleton based ceramic and polymer composites. As a first step the manufacturing routes for the CNT-skeletons alone will be stabilised to provide to the composite developers raw material with well-defined and reproducible characteristics. In a second step the composite manufacturing processes will be further developed on sample level and in parallel the dimensions of the CNT-skeletons will be scaled-up to 0.lm x lm with thickness ranging from few tens of micrometres up to few centimetres. In a third step, the CNT reinforced composite manufacturing will be stabilised on scaled-up dimensions, suitable for manufacturing technological demonstrators. Feasibility for processing large CNT buckypapers has been demonstrated while the different composite developers have verified compatibility of their processes with the CNT skeletons. Advanced integration and Test Services A number of different Electrical Ground Support Equipment (EGSE) systems exist in industry (e.g. Columbus CGS system) and have been in operation for many years supporting ESA and National space programs. Some of them are reaching their end of life and need to be replaced with better performing systems using state of the art technology, enabling an augmented portfolio of functionality. The goal of this activity is to provide a new ground software product line with reusable services and building blocks, applicable for all new projects, reducing the cost and risk for system development and production, which will improve the system competences and will enable seamless transfer of mission information. During this activity software building blocks will be designed and developed in an open, collaborative environment using open source tools. The Agile process principle will be applied, which aims at reducing costly overheads. The procedure will be iterative and incremental, producing running software right from the beginning of the project. Design and Development of a reconfigurable Telemetry Transmitter for earth observation Satellites Recent years have witnessed the ever increasing demand for high data links rate for Earth Exploration missions driven by the adoption of high resolution sensors, like the Synthetic Aperture Radar (SAR) or multi-spectral imagers. The main objective of this activity is to design and develop a flexible telemetry transmitter targeting Earth Observation missions and potentially Data Relay Satellite (DRS) applications implementing the ESA Serial Concatenated Convolutional Codes (SCCC) Standard . The major outcome will be a high rate TElemetry TRAnsmitter (TETRA) for the 26 GHz band built around a frequency-independent digital baseband unit capable of serving a number of missions. The telemetry transmitter will be qualified to Engineering Qualified Model level, performing a complete test campaign. TETRA will enable data transmission from satellite to ground in Ka-Band and alternatively in X-Band. The digital core will have a high degree of flexibility in terms of supported alternative standard air interfaces and available data rates, enabling the transmission of information data rates between a minimum and at least 2Gbps per chain, i.e. single transmitter. Such flexibility will allow the digital core to meet the needs of several target missions.
