An airplane's DME interrogator uses frequencies from 1025 to 1150 MHz. DME transponders transmit on a channel in the 962 to 1213 MHz range and receive on a corresponding channel between 1025 and 1150 MHz. The band is divided into 126 channels for interrogation and 126 channels for reply. The interrogation and reply frequencies always differ by ...
Typical US Air Force TACAN site using a dB Systems Model 900E TACAN Antenna. A tactical air navigation system, commonly referred to by the acronym TACAN, is a navigation system initially designed for naval aircraft to acquire moving landing platforms (i.e., ships) and later expanded for use by other military aircraft.
To solve this problem, a delay is added to the response signal that varies based on the code sent from the interrogator. When received by an enemy that does not see the interrogation pulse, which is generally the case as they are often below the radar horizon , this causes a random displacement of the return signal with every pulse.

A VOR/DME ground station in Germany In radio navigation , a VOR/DME is a radio beacon that combines a VHF omnidirectional range (VOR) with a distance-measuring equipment (DME). [ 1 ] The VOR allows the receiver to measure its bearing to or from the beacon, while the DME provides the slant distance between the receiver and the station.
A fearful subject is reassured "through verbal and physical actions" to calm him and cause him to view the interrogator as a "protector." Emotional-pride and ego-up. The subject is "flattered into providing certain information in order to gain credit and build his ego" using a "somewhat-in-awe tone of voice."
The Huffington Post has updated Hospice Check to reflect current inspection data. Since we first published this map in June, the number of hospices that haven’t been inspected in more than six years fell below 400, from 759. The average time since last inspection also fell, from 3 ½ years to just under three.
Conceptual of the ADS-B system, illustrating radio links between aircraft, ground station and satellite. Automatic Dependent Surveillance–Broadcast (ADS-B) is an aviation surveillance technology and form of electronic conspicuity in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts its position and other related data, enabling it ...
