Very cool! I could certainly take two of these. I have been looking for some USB GPS receivers but I have absolutely no idea bout them. It's tough to find one that seems reasonable/reliable. > I decided not to at this time order a lot of the Navisys GR-701-T, which is a > TTL interface with a PPS line.??

Makes sense. I'm looking at buying ~20 GPS chips and soldering up my own boards for them. This way if the chip fails all I have to do is replace that the rest of the parts will be robust. They're going to be cycled a lot so I expect a lot of failures over time. Amar.
