Re: GPS antenna for an outdoor autonomous vehicle?

I have used the older version of this GPS with this antenna with great success. We recently flew it on a balloon payload to 103,126 feet, getting data the entire flight except for an incorrect altitude during the first two minutes or so of flight (unknown reason, perhaps surrounding hills?) It reached a temperature of around zero Fahrenheit, and survived an ~80 mile (~130 minute) flight which included wind speeds up to 200 mph and a downward plunge at well over 500 MPH after balloon burst. (Not that those numbers have any impact whatsover on this device, but it's interesting to know how quick it got going at some points). I've yet to test it after impact/landing, but I have no reason to believe it wouldn't still work. It seemed to have no trouble getting a signal inside our foam payload box which was covered in mylar.
