DME Ground Station

In the context of aerospace engineering, a DME (Distance Measuring Equipment) Ground Station is a specialized terrestrial facility that is part of the aircraft navigation system. It uses radio signals to communicate with airborne DME equipment to provide precise distance information between the aircraft and the ground station. The DME Ground Station transmits a pair of pulses at a specific frequency, which is then received by the aircraft's DME system. The aircraft's DME system then transmits a corresponding pair of pulses back to the ground station. The time taken for the round trip of these signals is measured and converted into distance. This information is crucial for pilots to determine their aircraft's position and to maintain a safe and accurate flight path. DME Ground Stations are typically co-located with VOR (VHF Omnidirectional Range) facilities, providing both distance and direction information to aircraft, thereby enhancing the accuracy and safety of air navigation.
