They support NMEA protocoll so it should work.

They are so very cheap, 4 modules for 6.6 USD :O also found another latest version
http://www.ebay.com.sg/itm/fastrax-itra ... 505wt_1633

Both modules seem to have more features then standard GPS receivers and at 1/4 of the price, they have two UART outputs, spi interface, programmable controller etc

You will have to add a suitable GPS antenna (active or passive) to those modules.
RF matching of the antenna to a suitable co-axial cable then to the board / module is not a simple task, and, if not done correctly, could reduce performance significantly.

The NAVIGATRON V2 (I2C) and the DiyDrones MTK3329 (Serial) have suitably integrated "patch" antennas, providing optimum performance.

I guess for this price its not bad to Try

It's a six years old module, sensitivity is quite low, -151db versus the PA6B module's -165db. And there is no antenna (so add +15-20 usd for a good active antenna with SMA connector)
Max update rate is 4hz which is barely adequate, but you have to disable gps filtering.

Sorry if i'm out of context,
is there someone that have a Fastrax iTrax comptatible GPS receiver that sends data to a Server via GPRS, so that you can use data to show GPS position and status in Google Maps?

Thanks in advance,
