The problem with GNSS is that the kit to jam/spoof is sub-suitcase-sized. To jam/spoof LORAN-C or any other VLF system, you need several trucks: One for the generator, one for the antenna -- at least. That's the reason why LORSTA's have 600' antenna towers to begin with. LORAN-C may not be as precise, but it is very stable, which means that your dual-source nav-kit will tell you that GPS and LORAN-C diverges in ways that looks odd... The reason why we still have LORAN-C in europe, is that UK and France don't trust DoD to not play with GPS. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | 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 -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
