Yes, of course. The GPS receiver reports the location of the antenna. If you need to know some other location you have to apply some (x,y,z) offset from the antenna. Actually I doubt anyone would care about the location of the receiver. They might want to know the location of the vehicle's center of mass or the location of some display screen. The cable delay accounts only for the offset in time. Time and location really are different things, especially because a cable can take a non-straightline path or even be coiled up. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
