Title: Optical Wireless-Intra-Spacecraft Communications - Phase 1<br />
Optical wireless techniques are being considered for on board short-range communications in view of the potential mass and<br />
power re<strong>du</strong>ction, EMI immunity, and for the added benefit of increasing functionality and flexibility in S/C design, construction<br />
and testing. Recent advances in optical Micro and Nano Technology, the availability of high performance consumer-markets<br />
Opto-electronic components make today optical unguided links a feasible valuable approach for low mass, low power, high<br />
data-rate on-board space communications. Furthermore, the increasing bandwidth’s requirements for Earth Observation and<br />
Telecom payloads, the possibility to handle multi-user configurations, and strict S/C EMI immunity and cross-talk<br />
requirements, make optical wireless a very valuable solution to be thoroughly investigated.<br />
This investigation will consider the space environmental aspects, in particular radiation (electronics, electro-optics and optics<br />
components), the spacecraft internal environment (topology, materials reflectance and absorption) as well as the functional<br />
and operational aspects as a part of the on board data handling system (control and monitoring, telecommand<br />
distribution/telemetry acquisition functions).<br />
The proposed activity deals with the use of optical wireless techniques for on board communications, and in particular will<br />
cover the following technology areas:<br />
• Functional and performance specifications for on board optical wireless communications for control, monitoring, command<br />
distribution and telemetry acquisition as part of the Spacecraft avionics for a set of typical mission scenarios (platform type,<br />
mission profile, orbit) and in line with relevant CCSDS standards<br />
• Identification of the most suitable system configuration and architecture for selected applications/scenarios<br />
• Identification and selection of commercial/in<strong>du</strong>strial optical wireless communications systems (protocols, components)<br />
• Performance/reliability assessment of technology, components and devices<br />
• Assessment of Qualification for components and devices<br />
• Evaluation and characterization of Opto-electronic equipment/component and their interfaces<br />
• Selection of a Test application case from the preliminary set of applications scenarios to be used as System demonstrator<br />
• Definition of a Flight Test Demonstration based on the above<br />
• Preliminary design of the optical wireless communication system<br />
• Critical component and subassembly design and developments such as fast IR repeater<br />
• Development of Software tools for system analysis optimisation and computer aided design (link budget…)<br />
• Development of communication protocol and interface layers for selected configurations, operation and test environment<br />
software<br />
• Integration and Test of the Elegant bread-board of complete optical wireless systems for the selected applications<br />
• Consolidated technology road map and proposal for a flight demonstration based on the demonstration system.<br />
