Dear Jeff

I use a GPS receiver from GARMIN. It is called a GPS 35-HVS you can find 
information about it on there web site

http://www.garmin.com/products/gps35/

The unit ouputs GPS NMEA standard information which the specifications will 
tell you about, It also outputs RTCM data for differential location work. 
However most importantly and in your case it has a PPS (pulse per second) 
output which has to be enabled to work and beyond that only after it has 
locked onto the satelites.

It is fully encased so it can be left outside the unit has a built in 
antenna and a flying lead of about 4m. It is roughly the size of a computer 
mouse.

Any further help don't hesitate to ask
