Garmin has introduced two advanced Distance Measuring Equipment (DME) systems — the GGDM 4500 and the GDM 450R. These innovations are designed to enhance navigation capabilities for various aircraft.

Garmin’s digital, remote-mount solutions provide real-time slant-distance data that will allow pilots to track multiple Distance Measuring Equipment ground stations simultaneously when paired with compatible avionics. The GDM 450R is tailored for Part 23 general aviation aircraft, offering integration with Garmin flight decks and TXi displays, while the GDM 4500 is built for turbine-powered aircraft and helicopters, featuring enhanced durability and broader third-party compatibility through ARINC 429 support. Both models include advanced functionalities such as multi-frequency scanning, DME-DME navigation for precise RNAV routing, and Free Scan capability to automatically detect nearby DME stations.
