Department of Defense September 23, 2008 – Federal Register Recent Federal Regulation Documents

To enable an orderly and systematic transition, the U.S. Government has established December 31, 2020 as the date by which users of semi-codeless/codeless receiving equipment are expected to transition to using GPS civil-coded signals. Based on the current launch schedule and projected budget, the December 31, 2020 transition date represents the planned availability of the second and third coded civil GPS signals being broadcast from a minimum of 24 GPS satellites. Department of Defense will reassess the transition date should significant GPS program delays arise.
