The radio frequencies below the AM broadcast band have found several interesting uses over the past century. A modern-day use of these low frequencies is to disseminate data to correct GPS readings, especially for ships, boats and barges.

Gary Galbraith works with Nautel, a provider of DGPS transmitters to the US Government. We look at a DGPS transmission site in Mississippi and discuss this technology. We also discuss other “radio navigation aids” in the modern world.

Chris Tarr and Kirk Harnack are your hosts.
