However users do report much higher accuracy's using GLONAS and GPS+GLONAS systems as the Ruskies aren't filtering output at this time. That said, their satellites keep breaking down so its purely academic :-\ CR To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
