Hi Everyone,
If you are looking for a 1 pps reference I would advise QRP kits QLG1 .www.qrp-labs.com/qlg1.html 
It uses a MediaTek chipset which I believe is more accurate than the UBLOX. It is also more sensitive.  Mine works on the bench inside the shack, whereas the Ublox 6 and 7 both require an external antenna.  
What it does not have a configurable time pulse as the Ublox.

Hi all,

The cheap ublox GPS modules are used by many LF amateurs as a 1 PPS reference signal source. I see there are NEO-7M modules available at amazon, relatively cheap.

Is there any improvement of the Neo-7M over the Neo-6M? I had a look on the data sheets but can't find improvements on the stability or sensitivity, just the power consumption is lower for the 7M, about 60 mW less. That's 0.12 Ah per day when running on a '12 V' accu and a good DC/DC converter.
