Abstract
Several changes have recently been made to improve the real time physical approximation of UTC(USNO), the coordinated time scale generated by the U. S. Naval Observatory. A provisional UTC(USNO) is generated in real time, and a physical clock is steered to this time scale by a phase microstepper. When final values for UTC(USNO) are available, a method has been devised to steer the real time UTC(USNO) to match the final UTC(USNO). Further improvement will involve the adoption of an algorithm to generate UTC(USNO) on a real-time basis. Details of this new algorithm are presented.Keywords
