Thank you Attila :)
Actually the system for timestamping is at design stage yet.
I expect an event rate of about 100kcps, but I found little infos about
the bandwidth variable for the receivers.
Since I don't want to fill in the list with off-topic posts, just limit
in time-related quests.
There's not any problem for the board I'll use, I referenced the
raspberry because it's well known. My questions are for the software
side and relative efficiency of the system.
Best Regards,
Ilia.

I quickly read the gpsd howto and it explains what I want to do using
kpps on a raspberry. From there I can see a typical accuracy of 1uS, but
the informations of the live graphs page are precise down to the ns: are
these averaged?
What do you intend for granularity? Consider that I'm a newbie in
frequency/time specific terms.
If you are still going for the synchronization of telescopes, then
you definitly don't want a rpi. Go for one of the more industrial
oriented boards (the original rpi is basically just a graphics card with
an attached arm processor as USB controller). Like the beaglebone,
or probably even better for the Vybrid based boards (Colibry family)
from Toradex (has less EMI noise than the BBB).
