摘要

The altitude dependence of the electromagnetic field above the arctic path at a frequency of 300 kHz (GLONASS CCS) is considered. When comparing the altitude dependences of the modulus of the attenuation function |W| and field level E for the radio paths "ice-sea" and "sea" it is shown that the conditions for propagation of radio waves over ice-covered sea at reception altitudes up to 3-10 km are more favorable than over the open sea. It is established that the propagation over the ice paths depends on the height of the reception. The field of a vertical electric antenna over an "ice-sea" structure with highly inductive impedance exceeds the field of the earth's wave above the open sea. It decreases with increasing reception height. This effect is due to the concentration of the field above the highly inductive medium interface. Insignificant growth of the field above the sea occurs with an increase of the reception height.
