Virginia Tech expert to study solar eclipse effects on radar, ham radio, GPS

Greg Earle, W4GDE - a professor of electrical engineering, will head up a team of faculty, staff and students to study the effects of the eclipse on things like over-the-horizon radar, amateur radio, and even GPS. “Radio wave propagation is affected by the electrical part of the atmosphere and during the eclipse, we really have the opportunity to collect data and learn more about the impact of these changes on systems we’ve come to rely on,” said Earle.
