[time-nuts] Suggestion for a timing GPS receiver (Trimble / Ublox /other?)

Dear fellow nuts,

I plan to build a decent GPS/GNSS-based Stratum 1 NTP server, and I'm
looking for a good and possibly affordable timing GPS receiver.

Am I overlooking something or missing interesting options?

Cheers,

Paride,

As Mark notes, you don't need a timing precision GPS receiver for NTP, a 
standard position GPS receiver is quite good enough providing it has a PPS 
output.  If you're thinking Raspberry Pi, there are some ready-made modules 
such as:

Stephen mentioned the newer series-8 ublox modules.  These are indeed 
excellent (and can receiver Galileo too), but a number of vendors 
advertising series-8 modules (on both eBay and Amazon) are using remarked 
series 5 or 6 chips without the series-8 functions.  Use the ublox u-center 
program to check anything you buy.  From Amazon, at least, I got an 
immediate refund.
