The GPS reference we used was engineered by N6GN specifically for members
of our 2 meter WSPR study group listed on
http://www.qsl.net/kp4md/144_mhz_wspr.htm
That discussion thread can be followed at

A ready made solution to produce a 116 MHz local oscillator locked to a 10
MHz GPS disciplined reference is N5AC's VHF ApolLO at
