Alan,
Do yourself a favor and ring Chuck Busch of Trio. He is a genuine fellow,
with a wealth of information. Every negative you can think of has been
considered and even simple things like the 2 second refresh rate of a
handheld GPS using a NMEA 0183? data stream, in a turn to a given flight
planned track or ground track course, has been software modified to negate
the inaccuracy. He has 25,000 lines of code, so suffice to say I don't
think there is anything he hasn't thought about. He certainly gives me that
impression from my meeting. Worth a phone call I reckon, and he will
explain to you everything you want to know. It took 10 e-mails with worthy
responses before I was convinced, and my gut feel rewarded upon my personal
collection of my componentry.

P.S. There are those that might choose to call the servo old technology
used by Trio. It is, but it isn't standard, and there is a very detailed
explanation of why it is better. It is way beyond my understanding, but if
you have the knowledge, Chuck has the explanation. The head of the
autopilot is streaks ahead, and the accuracy ontrack is consistently less
than .01 of a mile as I recall. His target tracking was +/- .1 of a mile,
but tests prove it 10 times better than initially targetted.
