GPS modules ?

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)

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.

http://www.navman.com/oem/products/index.html

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.

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.

Cheeers

Have you had a look at Freescale's (Motorola) FS Oncore?

Or even the old standy, Garmin?

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'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
as output.

Try www.ublox.com.


You can even buy samples through their web site. IIRC, the
TIM-LP modules are about $110 each.

I'd rather see them on usenet kooks, trolls and spammers so we could
make sure they don't get near a working computer.

I'm sure they are quite useful to ranchers when livestock goes
missing.

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).

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?

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.

I recently bought a Polstar PGM-111 and are pleased with it. This is a

small GPS mouse so the antenna and magnet is built in. Power is 5 to
9Vdc. It has TTL and RS232 on the PS2 connector. The supplied USB
converter also can provide power (120mW appr. according to specs).
Output is NMEA. Chipset is SirfII so pretty modern.
Price was 70 Euro. If you are in the US, look at
http://www.brgsigns.com/GPS/ ($89).
