What prevents someone to fake an earlier timestamp?  Money can bend light, sure can a few msec.

It seems to me that all the markets have been doing this the wrong way.
Would it now be more fair to use some kind of signed timestamp and
process all transactions in the order that they originated?  Perhaps
each trade could have a signed GPS tag with the absolute time on it. It
would keep everyone's trades in order no matter how latent their
connection to the market was.  All you would have to do is introduce a
couple of seconds delay to account for the longest circuit and then take
them in order.  They could certainly use less expensive connections and
ensure that international traders get a fair shake.

If you want to shave off ms, using a source that takes at least minutes
to accrue enough signal for a single bit is definitely not what you
want. And drones across the Atlantic is way too Rube Goldbergesque to
contemplate.

Maybe they should invest into a dense, a really low LEO sat
constellation, and go by way of LoS laser.
