gps modules

[Heywood Jablome]

Hi all,

I'm looking for around 20 units of a gps module. Has anyone any sources for
good suppliers?

I have seen
http://www.sparkfun.com/shop/index.php?shop=1&cart=581190&cat=1&itemid=497&

which fit the ticket but am looking for the most cost effective way of
getting 20 units. If there are any cheaper units out there, i'm interested.

Also, the above is still a bit power hungry at 70ma which isn't much of a
concern, but is still a factor. Ideas and experiences appreciated.

A cheap way might be to use the popular consumer GPS-USB/RS-232 modules
for PCs. Search for "GPS Mouse" on eBay and you might get them cheap
out of the US or China etc. You might even be able to buy a bulk lot.

I think you'll be lucky to find anything under $100 each landed. I've
seen Globalstar and Holux USB GPS mouse units recently for around that
price. I bought a Holux GR-213 from a HK ebay seller, and it's a very
good unit.

Also, for the original poster - around 70mA isn't all that unusual.
Some modules have a kind of sleep mode, though, so depending on exactly
what you want to do, you may be able to get the total power consumption
over time down that way.

Check out Trimble's Lassen IQ model. Agent is either Stepgps (www.stepgps.com)
at Ringwood in Victoria, or Trimble Navigation in Fortitude Valley Queensland.

I picked up a GPS module from Rockby Electronics last year for $20. It has
TTL Rs232 output and runs on 5V. All you need to do is supply a suitable
antenna.

Is that 70ma with or without antenna ?

You can buy the laipac modules sparkfun sell from www.stepgps.com in
Victoria.
Good fast service when I used them.

All depends what you are after.

GPS for pc's , look at gps mice.

GPS for embedded use or remote mounting - one of the many modules

With the lassen IQ its cheaper to get the modules local
and buy pcb's(or carrier boards) from sparkfun.com

Sparkfun may give discounts for quantities , try emailing them.

Are you looking for 5V or 3.3V modules ?

M-Loc , SQ , IQ all are quite low power

A lot of modules seem to hit approx 120mA with embedded antenna
but get better results but higher power with miniture or larger antenna
