Discussion of Clock Residuals in Developmental GPS Satellites Measured with a Single Channel Receiver

Steven D. Chang and Timothy D. Maclay

Abstract:	The navigation potential of the NAVSTAR GPS system is integrally dependent on the ability to make accurate time transfer measurements. Examination of the clock offset data from several of the developmental GPS satellites shows systematic trends of unknown origin. By eliminating residual noise, a periodic behavior with a magnitude on the order of 30 to 50 nanoseconds is observed. A few possible sources of error, including improper application of relativistic calculations and limitations of the orbital and ionospheric models, are discussed.
