Correlated errors in GPS position time series: Implications for velocity estimates (2011, background): “In addition, the draconitic period varies for each satellite and over time [Choi et al., 2004; King and Watson, 2010], so its effect on position time series might not be purely harmonic.”
A review of time and frequency transfer methods (2008, background): “The geometrical relationship between the satellite, the receiving antenna and the reflectors that are the cause of multipath reflections has an approximate period of 1 sidereal day [8] (about 23 h 56 min), so that the amplitude of the multipath signal for each satellite also has this periodicity.”
Long GPS coordinate time series: Multipath and geometry effects (2009, background): “…the GPS draconitic year [ Ray et al. , 2008] in our time series demonstrates that an unmodeled subdaily signal, together with a satellite constellation with a repeat time of approximately 10s less than a sidereal day [ Agnew and Larson , 2007; Choi et al. , 2004] may contribute to these harmonics.”
Finding the repeat times of the GPS constellation (2006, methodology): “…of measurements intended to determine multipath, the importance of using this period to improve high-rate GPS positioning was first pointed out by Choi et al. (2004) in the context of GPS seismometry (Nikolaidis, 2002; Larson et al., 2003; Bock et al., 2004; Langbein and Bock, 2004; Genrich and…”
GPS sidereal filtering: coordinate- and carrier-phase-level strategies (2007, methodology): “…or in other words the number of considered epochs, decreases the apparent variability of the lag, which over the whole dataset tends to a steady value of around 86154 s (23h 55m 54s), i.e. not exactly sidereal, as previously reported by Choi et al (2004) based on the mean satellite repeat period.”
