Sparkfun's Logomatic v2. It's the only fast small logger I know of, and I've
been looking for them too. It uses a micro SD card for up to 2 GB and takes
57600 baud and maybe higher.
Note, this is a serial logger, you need to add the GPS module, an ideal being
Etek's EB-58 or newer equivalent, as it does 5Hz logging and from what I've
seen does better that SiRF 3. (It's MTK).
Trying to find a commercial unit to do what those two things can do might be
impossible, and if you did they'd charge you massively because it woult outdo
any commercial unit by a wide margin. The two modules are relatively cheap
though, and easy to put together, you just need a case and a Li-ion battery
with a charge circuit. (I think Logomatic even includes the charge circuit).
I have to add this... I tried two commercial types, and found that both
relied on proprietary closed source code to fetch the data from small flash
eeprom memory. The required programs were flaky at best, and wouldn't run on
W9X at all. Forget these units if you want fast versatile output, and do your
parsing direct from NMEA data. This way you're not bound to any specific
hardware, OS, or software. So long as you can read the Logomatic's SD card
either via USB, or by moving it to a reader, you have data.
I'm looking for a single unit that has a battery, a GPS receiver, and a
data logger for the coordinates.
I want to track a pet cat for a few hours a day, so speed isin't
important.
Something like this I guess:
