I would suggest that you could consider one of the Garmin GPS 16/17 models, 
that have been offered by Fluke1(China) at a sensible price. I have a GPS 
16HVS which is performing very well just sitting on a window-sill (facing 
North), this offers a 1pps timing signal. It requires between 8.0 to 40 
volts D.C (nominally 12.00 volts @ 40 mA. The alternative model, 16LVS, 
requires 3.3  to 8.0 volts.D.C @ 65 mA. All the data on these devices is 
available on the Garmin website
Good luck
