Tactical Data Links
A tactical data link (TDL) uses a data link standard in order to provide communication via radio waves or cable. NATO nations use a variety of TDL standards. All military C3 systems use standardized TDL to transmit, relay and receive tactical data. Multi-TDL network (MTN) refers to the network of similar and dissimilar TDLs integrated through gateways, translators, and correlators to bring the common tactical picture and/or common operational picture together. Change of terminology The term ''tactical digital information link (TADIL)'' was made obsolete (per DISA guidance) and is now more commonly seen as ''tactical data link (TDL)''. Tactical data link character TDLs are characterized by their standard message and transmission formats. This is usually written as <Message Format>/<Transmission Format>. TDL standards in NATO In NATO, tactical data link standards are being developed by the ''Data Link Working Group (DLWG)'' of the ''Information Systems S ...

Broadcast
Broadcasting is the data distribution, distribution of sound, audio audiovisual content to dispersed audiences via a electronic medium (communication), mass communications medium, typically one using the electromagnetic spectrum (radio waves), in a :wikt:one-to-many, one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and radio receiver, receivers. Before this, most implementations of electronic communication (early radio, telephone, and telegraph) were wikt:one-to-one, one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as ...

Internet Protocol
The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. IP has the task of delivering Packet (information technology), packets from the source Host (network), host to the destination host solely based on the IP addresses in the packet Header (computing), headers. For this purpose, IP defines packet structures that encapsulation (networking), encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information. IP was the connectionless datagram service in the original ''Transmission Control Program'' introduced by Vint Cerf and Bob Kahn in 1974, which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol (TCP). The Internet protocol suite is therefore often referre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

SIMPLE (military Communications Protocol)
{{About, the military communication protocol, the instant messaging protocol, SIMPLE (other){{!SIMPLE The Standard Interface for Multiple Platform Link Evaluation (SIMPLE) is a military communications protocol defined in NATO's Standardization Agreement STANAG 5602. Purpose SIMPLE defines a communications protocol to provide the means for geographically (national and international) separated Tactical Data Link (TDL) equipment ( C4ISR, C2 and non-C2 test facilities) to exchange environment data and TDL messages in order to conduct detailed TDL Interoperability (IO) testing. It is intended to provide specifications for a common standard to interconnect ground rigs of all types, such as simulation and integration facilities. The SIMPLE allows transmission of M-Series and J-Series messages over IP-based protocols. Previously J-Series messages could be sent using the Link 16 protocol. However, Link 16 is a radio protocol with a frequency range that limits the exch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Data Buffer
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes within a computer, comparable to buffers in telecommunication. Buffers can be implemented in a fixed memory location in hardware or by using a virtual data buffer in software that points at a location in the physical memory. In all cases, the data stored in a data buffer is stored on a physical storage medium. The majority of buffers are implemented in software, which typically use RAM to store temporary data because of its much faster access time when compared with hard disk drives. Buffers are typically used when there is a difference between the rate at which data is received and the rate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Interface (computing)
In computing, an interface (American English) or interphase (British English, archaic) is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral, peripheral devices, User interface, humans, and combinations of these. Some computer hardware devices, such as a touchscreen, can both send and receive data through the interface, while others such as a mouse or microphone may only provide an interface to send data to a given system. Hardware interfaces Hardware interfaces exist in many components, such as the various Bus (computing), buses, Computer data storage, storage devices, other I/O devices, etc. A hardware interface is described by the mechanical, electrical, and logical signals at the interface and the protocol for sequencing them (sometimes called signaling). See also: A standard interface, such as SCSI, decouples the design and introduction of computing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Link 22
Link 22 is a secure digital radio link in the high frequency (HF) and ultra high frequency (UHF) bands, primarily used by military forces as a tactical data link. Link 22 provides beyond line-of-sight (BLOS) communications. It interconnects air, surface, subsurface, and ground-based tactical data systems, and it is used for the exchange of tactical data among the military units of the participating nations. Link 22 will be deployed in peacetime, crisis, and war to support NATO and Allied warfare taskings. The Link 22 program was initially conducted collaboratively by seven nations under the aegis of a memorandum of understanding (MOU). The original seven nations were Canada, France, Germany, Italy, the Netherlands, the United Kingdom (UK), and the United States (US), with the US acting as the host nation. Spain has replaced the Netherlands as a NILE (NATO Improved Link Eleven) nation. Link 22 was developed to replace and overcome the known deficiencies of Link 11. Link 22 was a ...

Air Command And Control System
Air Command and Control System (ACCS) is the NATO project planned to replace the NATO Air Command and Control Systems of the 1990s. At the highest level it comprised the Combined Air Operations Centre (CAOC) from which the air battle is run. Beneath this level of command is the Air Control Centre (ACC), Recognized Air Picture (RAP) Production Centre (RPC) and Sensor Fusion Post (SFP) combined in one entity called ARS. The ARS is the equivalent to the Control and Reporting Centers (CRCs) operated in the 1990s. The ACCS project comprised both static and deployable elements. Under separate funding, NATO intended to procure deployable sensors for the deployable ACCS component (DAC). Oversight of the project is provided by the NATO Communications and Information Agency (NCIA) in Brussels, Belgium. Until 2012, this was executed by the NATO ACCS Management Organisation (NACMA) Board of Directors, senior representatives of the Nations engaged in the NATO ACCS project. The Board is respo ...

Time Division Multiple Access
Time-division multiple access (TDMA) is a channel access method for shared-medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same transmission medium (e.g. radio frequency channel) while using only a part of its channel capacity. Dynamic TDMA is a TDMA variant that dynamically reserves a variable number of time slots in each frame to variable bit-rate data streams, based on the traffic demand of each data stream. TDMA is used in digital 2G cellular systems such as Global System for Mobile Communications (GSM), IS-136, Personal Digital Cellular (PDC) and iDEN, in the Maritime Automatic Identification System, and in the Digital Enhanced Cordless Telecommunications (DECT) standard for portable phones. TDMA was first used in satellite communication systems by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Electronic Countermeasures
An electronic countermeasure (ECM) is an electrical or electronic device designed to countermeasure, trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of Radar jamming, jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile guidance, missile terminal homers. History The first example of electronic countermeasures being a ...
