The ACOSTA project intended to develop new tools for the numerical analysis and reliability analysis of large launcher structures. Its main work packages comprised: Domain decomposition/branching analysis, reliability and sensitivity, new shell elements.
The ADAM project was aimed at investigating the case that both the damping rate and the spring rate are non-linear and a function of the deflection, and that the damping rates and eigenfrequencies of the damper and the adjacent structure are different. This involved the development of a transient, non-linear finite element analysis model and correlation with a non- linear test specimen, a cable shock damper presenting highly non-linear behaviour.
The aim of this study is to investigate all new requirements of the Galileo Signal-In-Space, to discuss appropriateimplementation possibilities into the Advanced Signal Generator, to design programmable electronic components (Field Programmable Gate Arrays, FPGAs), and carry out the respective tests.
The ASOT project focuses on the development of a range of thermal vacuum insulation materials for spacecraft and other high technology applications. By appropriate surface patterning the material properties can be tailored to fit the requirements of the intended use.
The main goal is to optimise the cost function of such a commercial ASIC component qualification for space use by understanding all technological constraints. The results enable us to guide and support a subcontractor, which is inexperienced in space technologies, due to its background in the terrestrial market.
The project comprised the identification of existing technologies such as signal processors, general purpose microprocessors as well as ASICs and FPGAs, and the design of possible DSP architectures, two of which were evaluated in the course of the project.
The CORD activity aims at preserving the competitiveness of RUAG Space in the context of GPS receivers for future missions by performing the delta developments necessary to obtain a commodity GPS receiver, compliant with most of the future precise orbit determination (POD) receivers’ requirements.
The study aimed to investigate the actual requirements of manufacturers of SADMs, motors and satellite primes and to build and test a breadboard incorporating an innovative voltage control concept.
ARC Seibersdorf research GmbH was selected to develop and produce ion emitters for the experiment COSIMA (CometarySecondary Ion Mass Analyser). Scope of this experiment is to analyse cometary matter e. g. to find out what molecules existed shortly after the "big bang". There may be molecules, composed of hydrogen, carbon and oxygen, which might build blocks of amino acids, the basic molecules of life.
The function of Data Handling Systems on satellites is the collection of house keeping data for transmission to the ground (Telemetry Link) to allow the monitoring of the spacecraft status and the commanding of different spacecraft functions from the ground (Telecommand Link).
DIACERAM - High Thermal Conductive Ceramic-Diamond Substrates for Efficient Cooling of Next Generation of High Performance Space Electronics
The DIACERAM project focuses on the development of a next generation ceramic substrate material for application in electronic components.
The subject of this project was to design an embedded command and control subsystem (ECCS) as part of a satellite onboard electronics module based on the MIL-STD-1553B interface standard. In the present context "embedded" means that the subsystem is not implemented as a separate system formed by dedicated hard- and software, but that it is fully integrated into the extended hard- and software of an existing state-of-the-art spaceborne payload processor module.
The Austrian FEEP (Field-Emission-Electric-Propulsion) Technology for space application derived from the chargecontrol units developed for former space projects by ARC Seibersdorf research has been further developed since the Austrian FEEP Cooperation was founded. It has reached a technical status which promises to be very attractive forupcoming projects within the ESA Earth Observation- and Scientific Programme as well as the developing commercial market.
The goal of this research task is to demonstrate the long operating capabilities required for such missions that may exceed several thousands of hours as well as to build a cluster of several emitters that can still be operated by a single high voltage power supply. This cluster has to comply with increasing thrust demands by the satellites.
The project covers a detailed investigation of fretting phenomena during launch. The main challenge is to simulate conditions expected during the launch of a satellite. One part (one material) is subjected to very high acceleration and frequency while a second moves "freely" on it. Furthermore, the project will cover a review of requirements for testing, design, set-up and verification.
The goal of this project was to identify the best adhesive to avoid disbonding between metal and fibre reinforced plastic.
