Abstract : In addition to its national responsibilities in astronomy and time, the U.S. Naval Observatory (USNO) has also the responsibility for overall DoD PTTI management. This function, originally established by DoD Directive in 1965, has now become part of DoD Instruction 5000.2. This instruction emphasizes the need for a common time reference (the USNO Master Clock), in addition to the need for widest coordination to ensure worldwide continuity of precision. It also directs the appointment of PTTI managers from DoD Components to assist the DoD manager in the development of the Annual PTTI Requirements Summary, and in coordination of PTTI techniques among the Components. While the PTTI segment of the various electronic systems that use precise time is usually but a small piece of the action, it nevertheless is frequently the most critical one for the precise accomplishment of the mission. This is now generally recognized as one of the Lessons of the Gulf War: Accuracy Saves Lives As a consequence, we see today the emergence of another round of developments that aim at greater accuracy capabilities in the kind of scenario envisioned under the doctrine From the Sea. The PTTI technology is deeply involved in these developments and this paper gives some examples.
