A technique for using measured ionospheric density gradients and GPS occultation for inferring the nighttime ionospheric electron density

摘要

We present a technique for using the measured variations of ultraviolet emissions produced by radiative recombination at 911 or 1356 A in conjunction with occultation of Global Positioning System (GPS) satellites observed from a low Earth- orbiting satellite to infer the two-dimensional structure of the nighttime ionosphere. We present the results of simulations that demonstrate the applicability and accuracy of the algorithm and observation concept.
