Abstract :
The GPS Composite Clock defines GPS Time, the timescale used today in GPS operations. GPS Time is illuminated by examination of its role in the complete estimation and control problem relative to UTC/TAI. Simulated GPS clock phase and frequency deviations, and simulated GPS pseudo-range measurements, are used to understand GPS Time in terms of Kalman filter estimation errors.
