For the past ten months, the project “New Science in Radio Astronomy: Applying Cutting-Edge Technology to Enhance the Entire Data Chain, from Receiver to Final Output” (RADIOBLOCKS, Project No. 101093934, part of the HORIZON-INFRA-2022-TECH-01 program) has been underway at the Engineering Research Institute Ventspils International Radio Astronomy Center (VIRAC) of Ventspils University of Applied Sciences.
The RADIOBLOCKS project, which began on March 1, 2023, has a total budget of €10 million and involves over 30 partners from across the globe.
Progress in the RADIOBLOCKS Project
The VIRAC team has significantly contributed to the development of software for data processing across multiple Very Long Baseline
Interferometry (VLBI) networks, including EVN, ILT, ALMA, SKA, and EHT. This software is designed to benefit the global radio astronomy community. Additionally, the team has improved data processing algorithms previously developed by VIRAC. These enhancements, based on Karhunen–Loève Transformation (KLT) and Singular Spectrum Analysis (SSA) methodologies, will be applicable to observational data from EVN and ILT networks.
The results of the project may also advance single-baseline interferometry using the interferometer complex RT32–RT16 at Irbene and enhance LOFAR VLBI capabilities.
Key Activities Involving VIRAC
VIRAC is engaged in two major project work packages:
Detailed Results of Project Activities
WP4 Results
WP5 Results
Project Travel and Meetings
2. WP4 Planning Meeting (October 11–12, 2023):
A key conclusion from the WP4 meeting was the need for reusability of the developed results. To achieve this, a repository adhering to specific standards will be created, overseen by a DevOps working group led by ASTRON. Discussions also considered whether the final product should be a unified package containing all radio blocks or a set of independent modules. While no single application requires all radio blocks, a unified package remains an option.
Work plans, deadlines, and risks for individual project partners were reviewed. Although no significant risks were identified, clearer definitions of deliverables and interim goals were highlighted as essential.
