Texas air routes shift from old radio beacons to satellite navigation

The Federal Aviation Administration is changing air traffic routes in South Texas. It is replacing routes that relied on ground-based radio beacons with new routes that use satellite navigation.

For decades, air travel relied on a network of ground-based radio beacons. These beacons are expensive to maintain and are being phased out. This change means pilots will increasingly rely on GPS and other satellite systems for navigation, making air travel more efficient and less dependent on aging ground infrastructure.
