Single Channel Ground And Airborne Radio System
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. SINCGARS features provide communications interoperability for the Army, Marine, Navy, and Air Force, thus contributing to successful combat operations. It is also consistent with North Atlantic Treaty Organization interoperability requirements. The radios, which is hand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Friendly Fire
In military terminology, friendly fire or fratricide is an attack by belligerent or neutral forces on friendly troops while attempting to attack enemy/hostile targets. Examples include misidentifying the target as hostile, cross-fire while engaging an enemy, long range ranging errors or inaccuracy. Accidental fire not intended to attack enemy/hostile targets, and deliberate firing on one's own troops for disciplinary reasons, is not called friendly fire,Regan, Geoffrey (2002) ''Backfire: a history of friendly fire from ancient warfare to the present day'', Robson Books and neither is unintentional harm to civilian or neutral targets, which is sometimes referred to as collateral damage. Training accidents and bloodless incidents also do not qualify as friendly fire in terms of casualty reporting. Use of the term "friendly" in a military context for allied personnel started during the First World War, often when shells fell short of the targeted enemy. The term ''friendly fire'' ...

Selective Availability Anti-spoofing Module
A Selective Availability Anti-spoofing Module (SAASM) used by military Global Positioning System receivers to allow decryption of precision GPS observations, while the accuracy of civilian GPS receivers may be reduced by the United States military through Selective Availability (SA) and anti-spoofing (AS). However, on May 1, 2000 it was announced that SA was being discontinued, along with a United States Presidential Directive that no future GPS programs will include it. Before the advent of L2C, AS was meant to prevent access to dual-frequency observations to civilian users. SAASM allows satellite authentication, over-the-air rekeying, and contingency recovery. Those features are not available with the similar, but older, PPS-SM (Precise Positioning Service Security Module) system. PPS-SM systems require periodic updates with a classified " Red Key" that may only be transmitted by secure means (such as physically taking the receiver to a secure facility for rekeying or having a ...

Soldier Radio Waveform
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. JTRS HMS (Handheld, Manpack & Small Form-Fit (SFF)) radios are jointly developed and manufactured by Thales and General Dynamics Mission Systems. These software-defined radios are designed as successors to the JTRS-compatible CSCHR (Consolidated Single Channel Handheld Radios, ie. AN/PRC-148 and AN/PRC-152), securely transmitting voice and data simultaneously using Type 2 cryptography and the new Soldier R ...

Wideband
In communications, a system is wideband when the message bandwidth significantly exceeds the coherence bandwidth of the Channel (communications), channel. Some communication links have such a high Bit rate, data rate that they are forced to use a wide bandwidth Bandwidth commonly refers to: * Bandwidth (signal processing) or ''analog bandwidth'', ''frequency bandwidth'', or ''radio bandwidth'', a measure of the width of a frequency range * Bandwidth (computing), the rate of data transfer, bit rate or thr ...; other links may have relatively low data rates, but deliberately use a wider bandwidth than "necessary" for that data rate in order to gain other advantages; see ''spread spectrum''. A wideband Antenna (radio), antenna is one with approximately or exactly the same operating characteristics over a very wide Passband. It is distinguished from broadband antennas, where the passband is large, but the antenna gain and/or radiation pattern need not stay the same over the passband ...

RT-1523-VRC-89
The RT-15 was a mobile theatre ballistic missile deployed by the Soviet Union during the Cold War. It was assigned the NATO reporting name SS-14 Scamp (alternately the SS-14 Scapegoat) and carried the GRAU index 8K96. The RT-15 was an early Soviet attempt to develop a road-mobile theatre ballistic missile. It was intended to be capable of being launched from both sea and ground sites and had a maximum range of 2000–2500 km. The weapon's 'reaction time' in the normal readiness condition after its arrival at the launch site would have been 20 to 30 minutes and the 'holding time' at peak readiness (with a time of two to ten minutes before the missile could be launched) would be about a day. RT-15 was developed by the S. P. Korolev design bureau (OKB-1) on the basis of the second and third stages of the RT-2 ICBM. The missile was carried on a T-10 heavy tank chassis in a sealed container with a striking resemblance to the US Atlas D ICBM. After missile erection, the container ...
