Summary

Downloads the updated orbit files for the input synthetic aperture radar (SAR) data.

This tool uses the orbit type to make a call to the orbit website. Using the SAR metadata, it identifies the appropriate OSV file and downloads it to the input SAR data directory.

Three types of OSVs are available for a Sentinel-1 product: predicted, restituted, and precise. Predicted OSVs are provided with the Sentinel-1 Level 1 ground range detected (GRD) and single look complex (SLC) auxiliary products. Restituted OSVs are available through the European Space Agency (ESA) within 3 hours of image acquisition. Precise OSVs are available through ESA within 3 weeks of image acquisition. Sentinel-1 OSV files are downloaded from the Copernicus Sentinels POD Data Hub.

Usage

  • Login credentials are needed to download orbit state vectors. Get a guest username and password from the Copernicus Sentinels POD Data Hub.

  • If the SAR data was acquired within the last 3 weeks, set the Orbit Type parameter to Sentinel Restituted. This is available 3 hours after data acquisition.

  • To update the SAR data with the OSVs downloaded using this tool, use the Apply Orbit Correction tool.
