LINK 1 connects NATO units on land. It will gradually disappears on NATO land-based units and be replace by LINK 16 with the CRC system Interface (CSI) system developed by the Nato Programming Center (NPC).
LINK 4A is one - or two-way, nonsecure, UHF link between air control activities and controlled aircraft in the US forces
LINK 11 is a major Tactical Data Link - largely used in the NATO navies - which employs netted communication techniques for the exchange of tactical information among Participating Units (PUs). Data are secured and diffused through UHF or HF.
LINK 11B is a full-duplex, two way, point-to-point link to transfer data serially between Reporting Units (RUs).
LINK 14 is an old non real-time teletype Tactical Data Link. It will gradually disappears in major NATO operations.
IJMS provides an interim JTIDS capability for NATO, USAF and French Air Force E-3 aircraft and land-based units. It is progressively replaces by LINK16.
The general purpose of LINK 16 is the same as that LINK 11 and LINK 11B: the exchange of real-time tactical data among military units. While LINK 16 is identical in purpose to these links, it also provides some data exchange elements which they lack, and it provides significant improvements as well - such as "nodelessness", jam resistance, flexibility of communications, separate transmission and data security, increased numbers of participants, increased data capacity, network navigation features, and secure voice.
LINK 22 will replace LINK 11, with a lot of improvements derived from LINK 16 features. It is a NATO secure radio system that provides Beyond Line-Of-Sight (BLOS) communications over UHF and HF, with a integrated network management function (QoS) and an automated network entry process.
VMF will become a future multifunctional Tactical Data Link, based on the Variable Message Format already used in LINK 16.
The Joint Range Extension Application Protocol (JREAP) enables tactical data to be transmitted over digital media and networks such as satellite communications systems. The tactical digital messages are embedded in JREAP messages as data fields, and additional specialized management messages are also provided to transport data not contained in the formatted messages.
As stealth aircraft, F-22s are not equipped with conventional data links such as Link-16 which can be easily spotted by enemy SIGINT. Instead, they use a unique stealth-qualified, narrow-beam Intra-Flight Data-Link (IFDL) designed to relay data and synchronize a situational picture only among the Raptors. As this stealth datalink is incompatible with all other communications devices, Raptors cannot communicate with any friendly aircraft.
STSN : Sensor-to-Shooter Networking
Only one existing system, ROVER from L-3 COM
ROVER transforms sensor-to-shooter networking allowing increased levels of collaboration and interoperability. ROVER provides real-time full motion video for situational awareness, targeting, Battle Damage Assessment (BDA), surveillance, convoy operations and other situations where eyes on target are required.
CDL : Common Data Link (US DOD)
The Common Data Link (CDL) program is designed to achieve data link interoperability and provide seamless communications between multiple Intelligence, Surveillance, and Reconnaissance (ISR) collection systems operated by armed services and government agencies. CDL provides full-duplex, jam resistant, digital microwave communications between the ISR sensor, sensor platform, and surface terminals.
TCDL : Tactical Common Data Link (US DOD)
The Defense Airborne Reconnaissance Office (DARO) and the Defense Advanced Research Projects Agency (DARPA) are planning the execution of a technology and demonstration program leading to a Tactical Common Data Link (TCDL). The goal of the TCDL acquisition is to develop a family of CDL-compatible, low-cost, light weight, digital data links with the capability to support a wide range of Intelligence, Surveillance and Recognizance (ISR) applications.
