The OPERA people have elsewhere said that they calibrated the times using portable atomic clocks. If that is the case then the concern here, coordination from the GPS, shouldn’t be an issue.
I’m also a bit confused by where this paper is getting his 32 ns number. It seems to only work if the satellite is traveling roughly above and parallel to the neutrino beam. Any other orbital path should by his logic have slightly different results. Overall, this seems unsatisfactory.
Phil Plait thinks this explanation is unlikely to hold water..
