Application of MBSE to reverse-engineer OPS-SAT and improve OPS-SAT2

The main objective of the project is the reverse engineering of the OPS-SAT system, creating a model of the existing system design. The model aims to be built in a way that it is most useful for OPS-SAT engineers to understand and discuss the existing design and use this as a basis for further development of the OPS-SAT system.

Design for Recycling - Mission architectures to manufacture, refurbish and recycle satellites on-orbit

The main objective of the OMAR Mission Architecture study is to identify and trade-off different mission architectures, to provide different services on-orbit. For each of the relevant scenarios, this objective shall be achieved by defining the associated system functional analysis and by trading-off different architectures and concepts of operations. Furthermore, the impact of aspects such as: operational orbit, type of serviced satellites, services provided, different levels of autonomy, and any other relevant factors is to be assessed.

Harmonising MBSE standards into ECSS – Model-Based System Engineering – Study Scheme

ESA has traditionally specified space systems using a document-based approach, and is now in a transition process towards the digitalisation of systems engineering activities. At the same time, space industry companies have their own internal set of best practices and experience with Model-Based Systems Engineering (MBSE).

To solve this problem, ESA initiated this study led by CGI in partnership with OHB to identify a way to harmonise the different MBSE approaches from industry and compile the information into a concise book.

Development of a Compliant Mechanism Based on Additive Manufacturing
Compliant mechanisms (e.g. flexural joints) are applied where the relative motion of parts can be accomplished without using traditional bearings. Slender structures can be properly arranged to provide functions like accurate guiding, speed reduction, or change of motion direction. Compared to traditional mechanisms using bearings, significant improvements are expected. These include a decrease of part count number, frictionless motion transmission, which decreases losses, higher motion ranges, enhanced stiffness, and improved accuracy due to the avoidance of backlash.

Demonstration of Thermoplastic Composites
The following activities shall be accomplished:
 
  • State of the art review and establishment of application rang.
 
  • Selection of demonstration application for replacement of existing technologies. The application to be selected shall be a qualified part/subcomponent on an existing, qualified, space product.
 
  • Design and materials trade-off, including fibre and resin system, and preliminary design.

    De-risk assessment: Ceramic Packages for Magneto-resistive Sensors

    A GSTP De-Risk Framework with RUAG Space Germany designed and demonstrated a novel, compact and robust sensor head for angular sensors for space mechanisms, using modern and advanced materials and manufacturing methods.

    The final performance tests provided evidence in terms of high precision manufacturability of ceramic packages.

    The robust design was found to be suitable for the harsh space environment

    Improvement, Automated Source-code-based Testing
    State-of-the-art in automated unit/integration testing is a semi-automated approach for which the test environment is established manually, while execution of tests is automated. In contrast to that, the FAST approach already automates building of the test environment and the stimulation of the software, complemented by recording of input-output vectors, observed properties, anomalies and evaluation by metrics and filtering algorithms.

    Passive damped deployment of full composite structures

    This study aimed to demonstrate the feasibility, use and functionality of carbon fibre-reinforced flexible epoxy (CFRFE) materials for self-deployable space structures (such as deployable tape-spring hinges) by designing, simulating, manufacturing, testing and correlating a classic (100% carbon fibre-reinforced plastic -rigid resin- CFRP) deployable tape-spring hinge and a CFRFE deployable tape-spring hinge and compare their mechanical and dynamic behaviours.
