Objectives
The objective of the activity is to develop and test a scalable, generic and reconfigurable multibeam receive antenna architecture for feeder links, operating in V-band and supporting high-capacity, geostationary, broadband multimedia missions.
Challenges
The challenge of the project is the replacement of multiple (typically four or more) feeder link reflector antennas by a single antenna.
System Architecture
In order to assess the potential product features, various types of antenna architectures are part of the trade-off:
- active phased arrays magnified by reflector(s);
- active phased arrays;
- discrete lens antennas.
Suitable active components (LNA) identification, Beam-forming networks (BFN) typology, mass, volume, dimensions, complexity, thermal management, operational/ environmental constraints are the subjects to be optimised.
Plan
GRETA contract started on 01.03.2024. Expected project duration is 24 months.
The following project milestones are considered within the overall project development:
- KoM – Kick-Off Meeting;
- SRR – System Requirements Review;
- PDR – Preliminary Design Review;
- CDR – Detailed Design Review;
- TRR – Test Readiness Review;
- TRB – Team Review Board;
- FR – Final Review.
Current Status
The project’s PDR has been achieved.
