Abstract:

From Faraday fading of signal received from satellites the electron content of the ionosphere can be calculated. While crossing the ionosphere, the polarisation plane is rotated by a certain angle omega. This angle can be evaluated from the recorded signal - for instance by counting the number of half-rotations from the point of zero omega as defined by the M - type anomaly. The parameters needed for calculating the electron content from omega are magnetic and geometric factors. Several methods have been developed for calculating the above-mentioned parameters assuming a certain distribution for the Earth magnetic field. This note describes a method of calculating constants capable of replacing the parameters needed for evaluating the electron content in a defined zone near the receiving station. Constants for calculating gradients in the total content are described using the same method. Those constants are evaluated for the Haifa station as an example for this method. Author
