Abstract
Precise measurements of sea surface height from the Jason-1 and Jason-2/Ocean Surface Topography Mission satellite altimeter missions are being generated within seven and four hours, respectively, of real time by applying high accuracy orbit altitudes to their near-real-time altimetry products. The near-real-time orbit altitudes have respective accuracies of <2 and <1 cm (RMS), and the corresponding sea surface height measurements have accuracies of <4.0 and <3.5 cm, respectively. These near-real-time orbit solutions are computed using GPS-based precise orbit determination for Jason-2, and Jason-1/Jason-2 sea surface height crossover differences for Jason-1.
