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 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. -- Randy M.

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.

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.

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. Mark Borgerson>
