I have TOPS spilt a S1 product from 25 Jan 16. When I try to apply an orbit file the download fails. I manually downloaded the precise file from qc.sentinel1.eo.esa.int .
The downloaded file is in the auxdata\Orbits\Sentinel-1\POEORB\2016 local directory. The metadata shows empty values in the orbit state vectors.
How can I manually apply the orbit file to the spilt product?
