There is extensive online docmentation at www.u-blox.com, however you
will need to register to get at the online documentation. There are
PDF documents describing the hardware and software in great detail.
I've used the UBlox TIM-LP and GPS-MS1E in a couple of designs.
They run off 3.3V and provide CMOS level asynchronous outputs.
They can provide either NMEA or a binaryn packet protocol
You can even buy samples through their web site. IIRC, the
TIM-LP modules are about $110 each.
I'm using u-blox and their product line is really cool. Their are really
easy to use, output either nmea or their proprietary protocol (which I like
better) and they provide up to 4 fixes per second.
They are about to release their WS line (weak signal), that supposedly works
even indoors. I'm going to try it.
Try Furuno... I know they make some that are maybe 1/4" x 1" x 2" (6 mm
x 25 mm x 50 mm), connector for external antenna, 5.0 or 3.3 V, serial
output in standard ASCII formats. I think it's logic serial and you
need to follow with a MAX232 or equal to get RS232 serial. One antenna
I have seen used is a "puck" that is maybe 1/2" thick by 2" diameter (13
mm x 50 mm).
It's AUS$ 88.00 (inc GST) and there are different antennas about
AUS$50.00. You also need an adapter cable, for the antenna plus an
Very small unit. I'm looking at using them for GPS tracking.
