GPS does affect AIS perfofrmance but of course you'll need a GPS for
your nav package in order to calculate collision information (e.g.
distance from you, closest point of approach and time to closest point
of approach).

Thanks for that. Just to be clear, I have GPSes on my system and the
computer that will run my AIS software already has GPS positioning
data. What I think you are saying is that I should route one of the
GPSes through the SR161 when I install it to make the 161 work
better. Is that right?
