GPS & GLONASS. Information SourcesCivil GPS ServiceGPS Information CenterThe Civil GPS Service was established to provide civil GPS userswith information on system starus and a point of contact As a panof this Service, the U.S. Coast Guard has begun operations of theGPSIC on a "test and evaluation" basis. Current services includeGPS Operational Advisory Broadcasts containing current constellation starus. future scheduled outages, and an almanac suitable formaking GPS coverage and satellite visibility predictions. TheOAB 's are available 24 hours a day by computer bulletin board, oras a recorded telephone message at (703) 866-3826 (withoutalmanac).
