Wow thats a small GPS!

Posted by paul hubner on July 26, 2007 at 9:13pm
I decided for the sake of weight, I'd replace my Garmin Etrex Vista GPS on my plane (strapped piggback) with a dedicated chip version So I ordered one from Mouser.com. Mouser seems to have everything I ever need inabout 10 versions so its always a little daunting for me. This time I picked up a $28 GPS on a chip. If anyone cares its spec sheet is at http://www.tycoelectronics.com/gps/pdf/A1037-A.pdf.

Long story short -- read the specs first cause I forgot to get an antenna. Duh.

    Hi Paul,

    It looks like the propeller will be an awesome platform for a UAV controller! I'm just now gearing up to join in the fun. (I've done some BasicStamp and some PIC coding, so I'm hoping I can be helpful!)

    I agree that the A1037-A looks like a nice, light, and cheap GPS. Did you find a good antenna yet? I found this guy on mouser but haven't bought one yet...

    Any advice?

    Thanks!

    Paul,

    I use the Parallax GPS chip (which comes with an antenna!). It's a bit more expensive--$69--but it's a "smart" GPS, which is to say that you can send it queries and it sends back just the information you want, not a long string of NEMA sentences that you have to parse. (You can get the NEMA sentences too, if you want). It's got standard pin widths, so you can breadboard it. It's what we use with the Basic Stamp UAV.
