Smt compatible ELECTroMechanical relay for cOmpact redundancy Ring

Periodic Reporting for period 1 - SELECTOR (Smt compatible ELECTroMechanical relay for cOmpact redundancy Ring)

Reporting period: 2019-01-01 to 2019-12-31

SELECTOR contributes to the EC policy : “Reaching non-dependence in certain technologies will open new markets
to our industries and will increase the overall competitiveness of the European Space sector”. It focuses on the
development of innovative passive components to increase the number of freely accessible space qualified passive
components. SELECTOR aims at developing Surface Mount Technology (SMT) compatible electromechanical
switches for space sector high miniaturization. These devises called “Miniature Electro Mechanical Relay” (MEMR),
already exist for microwave industrial ground application like Automatic Test Equipment.
SELECTOR will deliver MEMR as part of ESA portfolio European Preferred Part List (EPPL) so that this high
integration, high performance passive component be available with noi restriction for the whole European industry.
SELECTOR will also demonstrate a whole new approach of self-redunded microwave equipment called “Metaequipment”
based on microwave specific SMT board level assembly and MEMR components to minimize cost and
improve integration. This demonstrator will address Very High Throughput Satellites (VHTS) emerging applications
where the new paradigm is the introduction of digital technologies dealing with very high number of RF chains.
VHTS system answers to telecommunication operator calling for optimized capital expenditure, no matter which
network, ground or space, to supply their products and services. New evolution toward high RF power and high
frequency capability will be implemented to open-up new sector of application within Space satellites (Navigation,
earth observation), but also non space sectors.
SELECTOR value chain includes a supplier of space passive component “Radiall”, a space integrator “Thales Alenia
Space”, a leader into electromagnetic design the “Universitat polytecnica of Valencia” and a center of excellence for
space reliability of high complexity miniature component the “CSEM”.
The activity carried out on the selector project during this first year focused on the following points:
- definitions of the specifications of the redundancy ring and the switch
- work on the architecture of the redundancy ring
- test plan for switch evaluation
- setting up a website
- setting up a dissemination strategy (publication, website etc ...)
- description of the innovative features of the selector switch
8 deliverables have been submitted
Significant progress has been made. An intermediate prototype switch was manufactured. The performance of the switch will probably reach specifications during 2020. At the same time, the architecture of the redundancy ring is fixed and the set up of a demonstrator will start this year. We have also fairly widely disseminated our activity through various communication channels. (website etc ...). The switch still needs to be improved, in particular on the waterproofing and to achieve the qualifications EPPL. The economic impact for Radiall should lead to the hiring of 4 people and about 200 people for Thales
