GPS module

Hi, I am looking for a GPS module to experiment with. To make sure I buy the correct module ( a break out, not a shield.) I looked on eBay, many of them state air flight controller, what does it mean? Are they just regular GPS? And also Does any one have recommendation on what is a good GPS module? Thanks.

the way they look, they-re just plain GPS modules with power and serial lines, not aircraft controllers. The Ublox6 ones should be fine.

If you want to make your experiment easyer pick one that can handle both 5V and 3.3V
