Time transfer techniques currently utilized by the public and private sectors rely heavily on external infrastructure, such as physical links or satellites. Time Transfer using Time Reversal (T3R) technique, pioneered by Dr. Eung-Gi Paek, is medium agnostic, therefore the technique can be applied to High Frequency (HF) radio waves. The use of HF radio waves allows long distance communications that is independent of any external infrastructure. In this paper, a long distance implementation of the T3R technique was demonstrated to compare the T3R technique to currently utilized time transfer techniques. This research effort was funded by DARPA.
