Christensen, E.J., Haines, B.J., McColl, K.C. and Nerem, R.S. (1994). Observations of geographically correlated orbit errors for TOPEX/Poseidon using the global positioning system. Geophysical Research Letters 21: doi: 10.1029/94GL02191. issn: 0094-8276.

We have compared Global Positioning System (GPS)-based dynamic and reduced-dynamic TOPEX/POSEIDON orbits over three 10-day repeat cycles of the ground-track. The results suggest that the prelaunch joint gravity model (JGM-1) introduces geographically correlated errors (GCEs) which have a strong meridional dependence. The global distribution and magnitude of these GCEs are consistent with a prelaunch covariance analysis, with estimated and predicted global rms error statistics of 2.3 and 2.4 cm rms, respectively. Repeating the analysis with the post-launch joint gravity model (JGM-2) suggests that a portion of the meridional dependence observed in JGM-1 still remains, with a global rms error of 1.2 cm. ¿ American Geophysical Union 1994
