The RAEGE correlator at Yebes Observatory

In this report, we describe the RAEGE correlator placed at Yebes Observatory. TheRAEGE network envisaged four stations across the Iberian peninsula, the Canary Islandsand the Azores in Portugal. RAEGYEB and RAEGSMAR, the first two stations of theRAEGE project, are already contributing to VGOS observations. The third station in thenetwork, located in the Canary Islands, is about to become a reality. Installed at the YebesObservatory, the software correlator will allow the observations of the network to beprocessed, as well as to serve as another contribution to the IVS. An Intensive campaignbetween the two operational antennas together with other stations has been established.Since 2021, we have been operating a small cluster to train staff in the correlation processusing DiFX and post-processing tools for geodetic applications such as HOPS, nuSOLVE,CALC/SOLVE, etc. During this period we processed about 100 experiments from variousprojects, including EU-VGOS and intensive sessions, most of them involving threestations. This allowed us to dimension the new HPC so that we could estimate anobservation time per correlation time factor of less than 1.
