Abstract:

Data from eighty-five passes of Satellite 61151 occurring from September, 1961, to June, 1962, are chosen to illustrate variations of electron density resulting from time of day, direction of the pass, and seasonal changes. Investigation of the plotted data indicate the variations in magnitude of the higher order refraction error terms. The data also show evidence of horizontal and vertical gradients i electron density. The Appendix presents an error analysis of the refraction error digital computation program from which the plotted data are obtained. Synthesized Doppler data with varying amounts of error are processed by the IBM 1620 and the results are shown. Author
