This comes as no surprise. I'm happy to learn about the details of your
findings on the off-list form.
It does bring up the point that the GPS receivers clock should either be
locked up or replaced with a stabler clock, preferably OCXO or derivate
there off.
Maybe time to do a small hack for illustratory purposes?
