There is a standard format called NMEA. Most receivers can provide this. In addition, most support a proprietary format. That one usually provided info specific to that receiver, like current settings and other vendor-specific stuff. There is a GPS moving map program that comes with SUSE. I think it may be called gpsdrive. It parses NMEA. We have our own highly optimized parser as we need the info quickly. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Kapellgränd 7 P.O.
