The Critical Design Review for the GERMINAL project was held at the EUSPA headquarters, in Prague, Czech Republic, the 6th of March 2025. It was performed in hybrid format, with most attendees being physically present in the meeting. There were representatives of all the entities that make up the GERMINAL consortium: IMDEA, UAB and GMV. The main discussion topic was the content of the documents delivered for this milestone, most of them providing an overview of the design and testing approach selected for both the Unified Hybrid User Terminal and the IoT SW receiver. Some minor corrections were discussed and clarified. Everything was resolved positively in the end, and the review was considered a success.

The CDR is one of the most important milestones in any project of this kind, as it marks the end of the design phase and the start of the actual development. From this point onwards, the team will focus their efforts into developing each of the modules of the UHUT, both in terms of hardware and software, and integrating them into a working terminal, testing all the components, separately and as a whole. This will be the longest phase of this project, taking up most of 2025. The next milestone will be the TRR, the Test Readiness Review. In this review, both the terminal and the receiver will be presented, and the testing phase will begin right after that point.
We will post regular updates with details about the design and the capabilities of the devices developed in the context of the project in our website and social media. Follow us if you want to be up to date! LinkedIn / X.
