Cross Track Vertical Deflection Accuracy of a Dual Satellite Altimetry System.
Abstract
Cross track vertical deflection uncertainty of sea surface from a dual satellite radar altimeter system is investigated in this study. The representative case simulated for study is 1000 km height satellites in nearly circular polar orbits. The along track separation of the two satellites is approximately 300 km which corresponds to a cross track radar coverage of 10 minutes of arc. Using gravity field perturbation alone, it is found 2 sec relative error of deflection of vertical as most optimistic while 4 sec represents a more realistic error. The 2 sec relative error of deflection of vertical agrees well with a similar simulation study done by the Applied Physics Laboratory, Johns Hopkins University. (Author)
