For very accurate astrometric results (arcsecond level), why not use dedicated
astrometric software like AstroRecord? You'll find it at the bottom of my
software page:

It will be crucial to check whether the GPS timestamp really conforms with the
opening of the camera shutter. Cameras have internal delays. Also, if you
measure both ends of a trail, check the true duration of exposures, as a
"15-second" exposure often is not 15.00 seconds (with some older Canons it can
be closer to 16 seconds!).

Good luck!
