We have compared GPS-based dynamic and reduced-dynamic TOPEX/POSEIDON orbits over a 10 day period beginning March 10,1993. The results suggest that the prelaunch gravity model (JGM-1) introduces geographically correlated errors which, when projectd on a mean sea survase, have a storng meridional dependence.
Topex/Poseidon is a satellite mission that will use altimetry to make precise measurements of sea-level with unprecedented acuracy such that small-amplitude, basin wide sea-level with unprecedented accuracy such that small-amplitude, basin wide sea-level changes caused by large-scale ocean circulation can be detected.
