Abstract
A communication system uses skywave propagation to transmit data between communication nodes over a data transmission path. An atmospheric sensor is configured to collect atmospheric data at the reflection point of the data transmission path where the transmission path is redirected from the atmosphere toward the surface of the Earth. Data collected by the atmospheric sensor may be used to predict future ionospheric conditions and determine optimum working frequencies for transmission of data between the communication nodes.

A system, comprising:
- a first communication node for sending a data transmission as an electromagnetic wave over a data transmission path using skywave propagation, wherein the data transmission path includes a reflection point where the electromagnetic wave of the data transmission is reflected by the ionosphere;
- a second communication node for receiving the data transmission from the first communication node;
- an atmospheric sensor configured to collect ionospheric data at the reflection point of the data transmission from the first communication node;
- a transmission frequency model for determining an optimum working frequency at which to transmit the data transmission over the data transmission path;
- wherein the transmission frequency model uses the ionospheric data measured by the atmospheric sensor as an input to determine the optimum working frequency;
- and
- wherein the transmission frequency model uses ionospheric data measured by the atmospheric sensor to encode a transmitted data signal.
