I download Sentinel-1 GRD products from https://search.asf.alaska.edu/. The original Geotiff image contains a lot of ground control points (GCPs) but not georeferenced. I georeference the images using GCPs by the following code
gdalwarp s1a-iw-grd-hh-20150117t091102-20150117t091131-004209-0051d2-001.tiff -tps 20150117.tif.
However, the geocoding information of different images is inconsistent after georeferencing.
I wonder what is the problem. Do I use the wrong command?
