ACCURATE SECOND-ORDER THEORY FOR TRANSIONOSPHERIC PROPAGATION,

Abstract

Measurements on high frequency signals from beacon satellites are used for calculation of the ionospheric columnar electron content. An array of antennae and a complex receiving system were necessary to measure dispersive Doppler shift, Faraday rotation and ionospheric refraction simultaneously on three frequencies: 20, 40 and 41MHz. Main emphasis is given to the development of a new second-order theory for phase path difference which considers, besides refraction and geomagnetic field effects, also the sphericity of the ionosphere. The correction terms caused by the sphericity dominate the second-order terms caused by the ray refraction. For several satellite passes the significance of the second-order effects is demonstrated.
