This morning I was listening to the Coast Guard's announcements to mariners and there was an announcement about the satellites. I found what they read doing an on-line search. To me it is very techno but I am sure there are some of you out there who would like to know this information.

Here is what they read: NOTICE ADVISORY TO NAVSTAR USERS (NANU) 2007105 NANU TYPE: GENERAL
*** GENERAL MESSAGE TO ALL GPS USERS ***
THE AIR FORCE GPS OPERATIONAL CONTROL SEGMENT WILL TRANSFER CONSTELLATION OPERATIONS FROM THE LEGACY MASTER CONTROL STATION (MCS) TO AN UPGRADED ARCHITECTURE EVOLUTION PLAN (AEP) NEW MASTER CONTROL STATION IN SEPTEMBER.

THE PHASED OPERATIONAL TRANSITION WILL MIGRATE EACH SATELLITE, GROUND ANTENNA, MONITOR STATION AND OTHER GPS DATA FEEDS FROM THE MCS TO THE AEP NMCS IN AN INCREMENTAL MANNER.
