The S1 OSV download functionality in S1.OSV.catch downloads files from https://step.esa.int/auxdata/orbits/Sentinel-1. Download from the Copernicus Open Access Hub / Scihub used to be possible but the service was shutdown and replaced by the Copernicus Data Space Ecosystem (see https://github.com/johntruckenbrodt/pyroSAR/pull/275). It would be good to implement download from there as second fallback option. However, implementation might be difficult because it requires authentication, which is not foreseen for the functions using this functionality.
