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.
Portable transceiver, Ultra high frequency (UHF)-band, 3,500 channels, 225-400 mc, 7 lbs: Collins Radio: AN/PRC-68 [160] AN/PRC-74: Portable HF radio: Hughes Aircraft (now Raytheon) AN/PRC-77: Portable Very High Frequency (VHF) radio, forward area, 3-5 Mile Range, replaced by Single Channel Ground and Airborne Radio System family of radios
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.
Link 16 is a TDMA-based secure, jam-resistant, high-speed digital data link that operates in the radio frequency band 960–1,215 MHz, allocated in line with the International Telecommunication Union (ITU) Radio regulations to the aeronautical radionavigation service and to the radionavigation satellite service.
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 ...
Multifunctional Information Distribution System (MIDS) is the NATO name for the communication component of Link-16.. 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, ground, and sea elements.
Single Channel Ground Air Radio System with Enhanced SINCGARS Improvement Program (ESIP), 30-88 MHz, FM, frequency hopping and single frequency; HAVE QUICK II military aircraft radio, 225-400 MHz, AM, frequency hopping; UHF SATCOM, 225-400 MHz, MIL-STD-188-181, -182, -183 and -184 protocols
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.
