GPS E-MAIL LIST SUBSCRIPTIONS

The U.S. Coast Guard offers a free, opt-in / opt-out  subscription email service for those users who have an urgent need to be notified of the publication of GPS status messages or new NANUs. GPS status email messages are sent daily; NANUs are sent whenever the GPS Constellation changes, generally within 60 minutes of notification by the Air Force to the Coast Guard of a change to the GPS constellation.

PRIVACY INFORMATION: These mailing lists are "opt-in". Disclosure of your email address is voluntary. It is solicited for the sole purpose of delivering the requested information to you and will not be released to any other party.
