Hi all, this article appeared in saturdays Courier Mail in Queensland and could of some concern to fellow Atlassers.   
                                           NAVIGATION DEVICE RISK
 
 
" Hikers, fishermen and sailors who rely on electronic navigation could find themselves lost on August 21 because of a bug in the global position satellite system.
The American-built satellite network calculates the date by counting the weeks since it was set up in January 1980.And when the counter hits 1024 weeks, it is programmed to restart at zero.
Warren Entsch, parliamentary secretary to the Minister for Science and Industry, yesterday warned that the zero date could cause some GPS recievers to look for satellites in the position they were nearly 20 years ago."
 
My concern is, is there any truth in this or is it just another one of those political beat-ups emanating from one of those paranoid American Congressmen or Senators. Cheers and enjoy the March - Paul Walbridge.
