Abstract:

A programmable pocket calculator is used to extrapolate the SEASAT orbit from the equator crossing to the position at which the synthetic aperture radar images a given target. The program predicts the coordinates of the satellite at image time, the Azimuth direction of the image at the target, and the time elapsed between equator crossing and imaging. Program predictions are compared with measured SEASAT data from the definitive attitude-orbit files. Author
