Sentinel-1D data release is scheduled for 2026-04-14 per https://dataspace.copernicus.eu/news/2026-4-2-sentinel-1d-user-data-opening-and-future-plans

These orbit formulae are published at https://sentiwiki.copernicus.eu/web/s1-products#S1Products-SARNamingConventionS1-Products-SAR-Naming-Convention :

While the S1D constant has not yet been published, 42 is the correct value for initial products currently published via the Copernicus Data Space Ecosystem. It's possible the number could change as the 1D satellite is moved into it's final orbit this summer.

once this is merged, could a new release be made please? So that we don't have to rely on a non-released version to process S1D data? Thanks!
