It is a timing measurement and it's not really designed to be precise. I belive the basic timing accuracy just below +/- 1msec. As the signal flies, that is +/- 300km. Projecting that onto the spherical planet, with an antenna angle around 40 degrees smears it out by a factor of roughly 1.5 and that's where the 740 km comes from. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ 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.
