Lachlan,
This would be fun to try with a few sites involved. It requires a fairly
decent GPS and antenna at each location, and loging and then
post-processing. Would be fun to see how well it can be made to perform.
Cheers,
Magnus

Hello all.
Having spent some time working over the last year on GPS time stability
measurement, I'm keen to move onwards and upwards and have a go at
common-view time transfer. While my receivers are in the post, I have
thinking about my next direction. One thought that I have had is to try to
write some software that can be used for real-time common-view (public if
there is interest, but I am getting ahead of myself I think).
My question to those in the know is whether they have found common-view to
be useful over medium timescales (say, an hour or four). My understanding
is that after a day or so the GPS signal itself becomes usable as a
standard, so building a network is probably not tremendously useful over
these sorts of time periods, but looking at such as figure 6 of [1],
common-view should still be useful between a few minutes and hours. Has
anyone here tried using such a method to produce their own short-term time
scale, or is one better off just taking the simple route and tracking GPS
time directly?
Thanks,
Lachlan
