All I was trying to say is that any reasonably determined hacker should be able to get something working. There is code out there you can copy. I haven't worked with any Trimble gear. I've only used gpsd a little bit. The code I looked at was good, even if I didn't study it enough to understand much of it. I was trying to debug some code talking to Garmin USB system and I wasn't getting anywhere. gpsd talked to it just fine so that told me the hardware and kernel were working. (or would work if you used the right magic) With that as a hint, I found the bug in my code. gpsd is primarily interested in navigation. It provides a clean API to many different types of GPS devices. It supports several binary protocols as well as NMEA, and it knows about various quirks in some NMEA implementations. I assume the delays and jitter associated with running through a server would be evil for timing, especially for the geeks on this list. But gpsd might be handy for getting off the ground. I haven't looked carefully at the Trimble support in ntp. A quick poke at google shows some discussion about adding Thunderbolt support, but I don't see it in the latest source code. http://www.eecis.udel.edu/~mills/ntp/html/drivers/driver29.html I'm willing to help with ntp issues. -- These are my opinions, not necessarily my employer's.
