The LOFAR4SW project has the past year made significant progress towards preparing for LOFAR2.0. In particular, the project has accomplished the import milestone of commissioning a testbed prototype station called UK902. It is located at the Chilbolton Observatory in the United Kingdom, alongside the existing UK608 station. Building started August 2019 and first light was on the 19 September 2020. Although it does not use the LOFAR2.0 infrastructure – in fact it is only 4 LOFAR1.0 HBA tiles and half the nominal number RSPs (Remote Station Processing) – it has allowed the LOFAR4SW project to implement end-to-end testing of the main data reduction pipelines. Tests have also allowed the project to quantify back-end data reduction requirements.
