A data link is the means of connecting one location to another for the purpose of transmitting and receiving digital information. It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink.
MIL-STD-188 is a series of U.S. military standards relating to telecommunications.
The Defense Information Systems Agency (DISA), known as the Defense Communications Agency (DCA) until 1991, is a United States Department of Defense (DoD) combat support agency composed of military, federal civilians, and contractors. DISA provides information technology (IT) and communications support to the President, Vice President, Secretary of Defense, the military services, the combatant commands, and any individual or system contributing to the defense of the United States.
In NATO, a Standardization Agreement defines processes, procedures, terms, and conditions for common military or technical procedures or equipment between the member countries of the alliance. Each NATO state ratifies a STANAG and implements it within their own military. The purpose is to provide common operational and administrative procedures and logistics, so one member nation's military may use the stores and support of another member's military. STANAGs also form the basis for technical interoperability between a wide variety of communication and information systems (CIS) essential for NATO and Allied operations. The Allied Data Publication 34 (ADatP-34) NATO Interoperability Standards and Profiles which is covered by STANAG 5524, maintains a catalogue of relevant information and communication technology standards.
Single Channel Ground and Airborne Radio System (SINCGARS) is a Combat-net radio (CNR) used by U.S. and allied military forces. The CNR network is designed around three systems: SINCGARS, the high frequency (HF) radio, and the SC tactical satellite (TACSAT). Each system has different capabilities and transmission characteristics. SINCGARS is a family of user-owned and operated, very high frequency-frequency modulation (VHF-FM) CNRs. In the CNR network, the SINCGARS’ primary role is voice transmission for command and control (C2) between surface and airborne C2 assets. SINCGARS can transmit and receive secure data and facsimile transmissions through simple connections with various data terminal equipment.
Tropospheric scatter, also known as troposcatter, is a method of communicating with microwave radio signals over considerable distances – often up to 500 kilometres (310 mi) and further depending on frequency of operation, equipment type, terrain, and climate factors. This method of propagation uses the tropospheric scatter phenomenon, where radio waves at UHF and SHF frequencies are randomly scattered as they pass through the upper layers of the troposphere. Radio signals are transmitted in a narrow beam aimed just above the horizon in the direction of the receiver station. As the signals pass through the troposphere, some of the energy is scattered back toward the Earth, allowing the receiver station to pick up the signal.
A two-way radio is a radio that can both transmit and receive radio waves, unlike a broadcast receiver which only receives content. It is an audio (sound) transceiver, a transmitter and receiver in one unit, used for bidirectional person-to-person voice communication with other users with similar radios. Two-way radios are available in stationary, mobile, and hand-held portable models. Hand-held two-way radios are often called walkie-talkies, handie-talkies or hand-helds. Two-way radios are used by groups of geographically separated people who need to keep in continuous voice communication, such as aircraft pilots and air traffic controllers, ship captains and harbormasters, emergency services personnel like firefighters, police officers, and ambulance paramedics, taxi and delivery services, soldiers and military units, fast food and warehouse employees, and radio amateurs.
Land Warrior was a United States Army program, cancelled in 2007 but restarted in 2008, that used a combination of commercial, off-the-shelf technology (COTS) and current-issue military gear and equipment designed to:
The Joint Tactical Radio System (JTRS) aimed to replace existing radios in the American military with a single set of software-defined radios that could have new frequencies and modes (“waveforms”) added via upload, instead of requiring multiple radio types in ground vehicles, and using circuit board swaps in order to upgrade. JTRS has seen cost overruns and full program restructurings, along with cancellation of some parts of the program. JTRS is widely seen as one of the DoD's greatest acquisition failures, having spent $6B over 15 years without delivering a radio.
Link 16 is a military tactical data link network used by NATO and nations allowed by the MIDS International Program Office (IPO). Its specification is part of the family of Tactical Data Links.
Bowman is the name of the tactical communications system used by the British Armed Forces.
Link 22 is a secure digital radio link in the HF and UHF bands, primarily used by military forces as a tactical data link.
The British Armed Forces operates a wide range of communications and information systems. Some of these are specialised military systems, while others are procured off-the-shelf. They fall into three main categories: satellite ground terminals, terrestrial trunk communications systems, and combat net radio systems. Every part of the Army and the uses combat net radio, but only the Royal Corps of Signals and the Royal Air Force operates trunk systems and multi-channel satellite communications.
The defense industry of Turkey has a long history, dated from the Ottoman Empire and changed several times.
PM WIN-T is a component of Program Executive Office Command, Control and Communications-Tactical in the United States Army. PM WIN-T has been absorbed into PM Tactical Networks as Product Manager for Mission Networks.
The Mounted Soldier System (MSS) or Ground Warrior is a combat vehicle crewman ensemble integrating advanced gear as an effective force multiplier in combat theater.
33 Signal Regiment, formerly known as 763 Communication Regiment, is a primary reserve Canadian Army unit of the Royal Canadian Corps of Signals in Ottawa, Ontario.
A ground segment consists of all the ground-based elements of a spacecraft system used by operators and support personnel, as opposed to the space segment and user segment. The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground. The primary elements of a ground segment are:
Thales Italia Spa - Chieti Site, a subsidiary of the Thales Group, has been until 2016 a leading manufacturer of tactical communications equipment, including the ST@RMille, TR@CER, MELANIE Systems and ESTHER CBRN Systems currently fielded with the Italian Army and NATO forces worldwide. It is currently involved in the Joint Tactical Radio System program, fielding its radios.
