Could someone recommend a gps module suitable for use
in embedded projects (pic and lpc21xx) , robotics and hooking up to a
(laptop/pc with windows and osx drivers).
Either 3V or 5V powered, ASCI output via rs232 or i2c or spi - (NMEA 0183)
and under 10cm by 10cm (5cm by 5cm or under would be better).
Start up time isn't a concern , up to a couple of minutes is fine
Quite a few out there, just wondering which ones people use more and
are fairly cheap , easy to use , reliable and rugged/robust.
I had a bit of a look at a few (first three look quite good)
UV40 - Laipac
TF30 - Laipac
Lassen iQ - Trimble
Rikaline GPS-23
Jupiter 12
Leadtek 9543

Re: GPS modules ?

Hey Alex, have you looked at Navman? I think they're over on your side
of the globe, NZ. See the Juptier Pico and Calisto.

I've used the Jupiter 11. Nice thing is they have a dead reckoning
input, for wheel sensors, so they can do a better job of predicting
motion. Reasonably priced, I thought.

Re: GPS modules ?
Hi Alex,
How's the cricket going?
Seriously, though, I am a newbie, but have come across some interesting
articles on interfacing to GPS. One is in Everyday Practical Electronics,
Jan 2004 issue, ( go to web site for assembler code - you will have to muck
about a bit with their Assembler application software to translate it to
Microchip's MPASM format -
http://www.epemag.wimborne.co.uk/downloads.html ), but it is very in -
depth.
Or, there has been a couple of articles in Nuts n Volts (USA) magazine using
the BASIC Stamp (search through www.parallax.com website for the article).
I think these projects used Garmin.
I can e-mail the first article or post it here if u like.

Re: GPS modules ?
You can buy combined GPS modules and antennae for about $80 off the net (try
eBay).
These small devices can be obtained with either a standard RS232 or USB output.
They put out the information in standard NMEA format (which basically means that
it can be read directly by a microprocessor).
I am using them with a Picaxe08 micro to monitor the movement of cattle via a
small solar-powered collar around their neck. And for RC airplanes with a tiny
300 MHz (approx) transmitter from Oatley.

I read in sci.electronics.design that Michael A. Terrell

Where are you going to put a troll or spammer that they wouldn't come
within the tracking error(say 20 meters in an urban canyon) of a
working computer?

So how do the cows transmit back their position? Or do they log
the positions to see where the cows go when they aren't watching?

Re: GPS modules ?

I was thinking more along the lines keeping them at the bottom of the
Grand Canyon.

You've got me. I haven't been near a live cow in almost 39 years. I
prefer my cows already processed. In fact, there's some beef cooking in
my crock pot full of chili right now.
I didn't start the part about the digital cows, I just commented on
it.

Re: GPS modules ? Far Side

I hadn't even looked for one after they announced they would no
longer be available in the US. I've only visited the big bookstores a
couple times in the last couple years. No electronics books or
magazines worth buying so when they said the 365 day "Cartoon a day"
calendar was no more I stopped going.

Try the big bookstores' websites, they stock much more than the
retail stores. When you find what you want, you can check competitive
with comarison sites such as <http://addall.com . Hmm, searching for
Far Side Calendar returns current titles at links 5 and 6.
