Hi all, Stock is running low on the Trimble Copernicus and I've already stopped stocking the Garmin GPS 15. Those are the two small GPS receivers I've been carrying for high-altitude use, but the Copernicus takes some serious work to integrate and the GPS 15 is getting a little dated.
Can anyone suggest a good GPSr module with integrated antenna, preferably one that works above 60,000 feet? I figure I'll just drop the Copernicus and GPS 15 entirely when they're gone and start carrying a new unit. I've got samples of a SiRFStar III receiver with an integrated Sarantel Geohelix antenna that I like, but like all of the other SiRFStar IIIs it's no good for high altitudes. Scott N1VG
