[ABraun]

From the Help file:

The orbit state vectors provided in the metadata of a SAR product are generally not accurate and can be refined with the precise orbit files which are available days-to-weeks after the generation of the product.
The orbit file provides accurate satellite position and velocity information. Based on this information, the
orbit state vectors in the abstract metadata of the product are updated.

Applying orbit files in SNAP:
Menu > Radar > Apply Orbit file

Things to keep in mind:

@peter.meadows

Note that the orbit data included with the product is of high accuracy. For even better accuracy you will need to wait for the AUX_POEORB (generated about 3 weeks after the acquisition).

@mengdahl

In practise the restituted orbits are of very high quality, you can try processing with them already now as the improvement the precise orbits will give you is rather minor.
