## Summary

This talk was presented on 2020 April 18 at the 2019-20 NASA Arizona Space Grant Symposium. The event was virtually available via Zoom.


Submitted abstract:

The Ionosphere is a layer of the atmosphere that contains a high concentration of electrons that can affect signals passing through it. My research aims to answer how the Ionosphere and Earth’s magnetic field affect high-frequency signals traveling from a low orbit satellite to a given ground station. The purpose of this work was to predict changes in Group Delay, Faraday Rotation, and frequency. This will be used in the CatSat project to predict and analyze an experiment satellite-to-ground propagation effects. Equations to predict these ionospheric effects were derived starting with the satellite’s orbit, ground station location, and Total Electron Content (TEC), assuming a spherical Earth, a dipole magnetic field, and a non-varying thin Ionosphere. Models verify that the slant TEC increases at lower elevations and the polarization rotation reverse direction as the satellite approaches the north magnetic pole. Future work includes finishing calculations for induced Doppler shift.
