Thanks to all for your responses.
Mike:
1 Yes, I have had problems using some USB GPSs on other SBCs running
Linux: The drivers were proprietary and just did not seem to work on
the h/w. I bought a different USB GPS and it worked just fine.
That's why I asked about an 'out of box' experience. I don't want to
go down that road again, and thought I would ask directions first ;)
Sounds like good old RS-232 is a safe bet in this regard
mark_s:
1. Instead 'a few meters' I really meant 10-20 meters. Basically I
need to determine which job site a piece of equipment is/was on, so
accuracy is not a huge issue
2. Sounds like WAAS gives the added accuracy transparently to the
user, without additional off-chip requirements (additional receiver),
so requirements not withstanding it is probably a good thing, on the
principle that more accuracy is better than less, especially if it
comes at a low cost, complexity wise
3. Once a second is fine for a sample rate. The requirement is more
like once a minute, or every five
minutes. We are not doing navigation or anything like that, and these
things don't move that fast or that often
4. Speaking NMEA-0183 by default, as opposed to binary/proprietary
sounds very good to me, too.
Bas Schulte:
1. Yes, I plan to use gpsd. I have used it in other systems and found
it very useful. I understand there is now a API that avoids the
socket maintenance code, which should make the source code a little
cleaner.
2 I looked at sparkfun, and there a lot of interesting GPS modules
there. However, being a software guy, I am not sure how to connect
them to the TS-2760 without using their eval boards and a serial port
or USB interface. Seems like it must be fairly straight forward, but
I have not done the research yet. I very much like the idea of
having the GPS internal to the enclosure (except for the antenna)
Again, thanks to all for taking the time to write and share your insights.
