A PROGRAM FOR COMPUTING THE IONOSPHERE TILT ANGLES FROM THE RADIO RAY ARRIVAL ANGLES.

Abstract

From the distance between the transmitting and receiving stations, the height of the radio ray reflection, and the arrival angles of the radio ray at the receiver, this program will determine the attitude of the tilt vector of the ionosphere at the point of reflection of a single-hop propagation path. In addition the perpendicular deviation for the transmitter-receiver great circle bearing to a point directly under the point of the reflection is also computed. In order to establish a suitable model of the problem, it is assumed that: (a) The propagation path is represented by its Martyn equivalent; (b) the ionosphere is a plane mirror at the point of the reflection; (c) the earth is a sphere with a radius of 6371.22 kilometers. This program is coded in FORTRAN. The computer involved in this case is a Control Data Corporation G-20 using the SPACE programming system. (Author)
