[time-nuts] 1 pps Sync'ing

I am a newbie question.
I have an application where I have a 10 MHz and 100 MHz squarewave output from my GPS frequency standard.
The frequency standard uses the PRS10 rubidium. The 100 MHz output is just a 100 MHz VCO locked to the 10 MHz.
These outputs are disciplined by the GPS's 1 pps (as far as frequency). But they are not in phase with it.
I need the rising edges of both the 10 MHz and 100 MHz squarewave outputs to be aligned with the GPS 1 pps (UTC) to within 1 ns.
Anyone already done this? I'm sure I've seen a distribution amplifier that does this at 10 MHz.
But the 100 MHz is actually the more important one that I need to align.
