You can probably get them anywhere, but I just found them on that site recently.

Yep, I was aware of their existence, I just didn't realize they were so
cheap :)<br>

According to Maning, the guys in Davao did just that:

This is perfect for mapping from a car, which is fortunately most of
the time.<br>
However, if I go on a long trip on foot, the laptop will eventually run
out of
battery, so I can't depend on logging straight to TagoGPS all the time.<br>

I'm not sure how that worked exactly, but tangoGPS uses gpsd, so anything that can communicate with that will work. I was using a bluetooth dongle, but a USB connection would work just as well, as long as Ubuntu recognises it. You have to fiddle with rfcomm a bit I seem to remember. Hopefully those pointers will give you enough to go on.
USB -> rfcomm -> gpsd -> TangoGPS
The only 'gotcha' with the GT-31 is that its waypoints dump needs to be converted to a recognisable format on a windows box. So you'd sidestep that if you were logging directly to TangoGPS.

Very useful, Jim! Thanks a lot for that.<br>
That gotcha is definitely a big gotcha. I don't stock windoze
computers, so that would be pretty annoying. <b>Does anyone know of
any gps loggers that can be bought for a reasonable amount of money
that does NOT use some obscure proprietary file format?</b><br>
I'm still in the UK so I can get one from here if needed.<br>
I could always use my dusty old Win2k VM, which I'm sure I can dig out
from my backup hard drive somewhere, but I can't remember if USB was
even invented at that time, not do I know if it will work in VMWare.
But I really just want to avoid reliance on proprietary stuff. I want
to be able to help others with this after I've done it, and people that
know me knows very well that I will never say "then just start up
Windows to download and convert this file". There must be a better
solution.<br>
Will search for some linux friendly GPS loggers on Amazon later :)<br>
<br>
Ronny.
