Like Magnus just wrote. The xyz determined by the receiver are those of the antenna. No matter how long a coax there is between the antenna and receiver. However the coax delay adds to the GPS receiver clock error, which is why timing receivers usually let you put in a constant to cancel for this. But its up to you to measure your coax, the receiver have no way of doing this. -- Björn _______________________________________________ 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.
