Dynamic Satellite Time (DST): Real-Time Calibration
and Bidirectional Synchronization with TAI
René Oudeweg / Claude Opus

Abstract

We propose Dynamic Satellite Time (DST), a time scale derived from the 
orbital dynamics of artificial satellites, analogous to how Ephemeris 
Time was derived from lunar motion. Unlike historical astronomical time 
determination, satellites enable true real-time calibration through 
onboard atomic clocks, continuous tracking, and rapid orbital motion. We 
demonstrate that bidirectional calibration between DST and International 
Atomic Time (TAI) is not only possible but is already partially
implemented in modern satellite navigation systems. This represents a 
fundamental advance over the Ephemeris Time era, combining the 
independence of dynamical timekeeping with the precision and real-time 
accessibility of atomic standards.
