An airborne TACAN receiver can be used in air-to-air mode to provide the approximate distance between two coordinating aircraft by selecting channels with 63 channels of separation (e.g., aircraft #1 sets channel 29 into its TACAN and aircraft #2 sets channel 92 into its TACAN.). It does not provide relative bearing.
The SINCGARS operates on any of 2320 channels between 30 and 88 megahertz (MHz) with a channel separation of 25 kilohertz (kHz). It accepts either digital or analog inputs and superimposes the signal onto a radio frequency (RF) carrier wave. In FH mode, the input changes frequency about 100 times per second over portions of the tactical VHF-FM ...
The reply frequency is different for X and Y channels, and different for channels numbered 1-63 and 64-126. Not all defined channels/frequencies are assigned. There are assignment 'holes' centered on 1030 and 1090 megahertz to provide protection for the secondary surveillance radar (SSR) system.
However, the military secretly developed a largely duplicate system called TACAN. The system was revealed in 1952, but work continued into 1955, when the redundancy of effort caused controversy. [3] [a] The following year an agreement was reached, where civilian operators would adopt the VORTAC system. [5] VOR/DME symbol used on aeronautical charts
Multifunctional Information Distribution System (MIDS) is the NATO name for the communication component of Link-16 developed by Xetron. [1]MIDS is an advanced command, control, communications, computing and intelligence system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air ...
The 1090 MHz frequency (paired with 1030 MHz) is also used by Mode S transponders, which ADS-B augments when operated at this frequency. The TCAS system also utilizes the 1030/1090 MHz paired frequencies. ADS-B information can also be broadcast on the L band frequency of 978 MHz. DME and TACAN systems are also in this frequency band.

A Loran-C receiver for use on merchant ships Loran-C sound as received on an AM receiver at 100 kHz. Loran-C is a hyperbolic radio navigation system that allows a receiver to determine its position by listening to low frequency radio signals that are transmitted by fixed land-based radio beacons.
