Upstream Ancillary Ingest is the first subsystem in the processing pipeline. It manages keeping the SDS archive upto date with:

  • Orbits - precision and restituted

  • Calibration files

  • Acquisitions

Why keep up?

  • Our pipeline is triggered by the ancillaries

  • SDS archive should always be in sync with SciHub

  • Failure to do so results in failure in processing pipeline

  • Advantage - At time of urgent response, we need not depend on uptime of external service as we have our own local metadata archive (GRQ acquisition index).

I presented the necessity of the Ancillary Ingest at ESIP Summer Meeting 2019. Here are the slides:

They may be helpful to understand the whole picture.
