HAVE QUICK
HAVE QUICK is an ECM -protected military wideband frequency -hop system in the aeronautical mobile service, is 225-400 MHz frequency availability for harmonized in the NATO -wide UHF band.
Development
After the Second World War, the United States and the Allied air forces took advantage of AM radios in the NATO harmonized UHF frequency band 225-400 MHz for short-range wireless applications to quasi-optical sight air -to-air and ground -to-air. First, consisted in the development phase, during the procurement and for subsequent use by the military users no claims regarding secure communication and protection from enemy interference for aircraft and helicopters. With the rapid development of electronics in the aftermath of the Vietnam War to the 1970s, eventually a point was reached, could be clarified, intercepted and disrupted with an extremely simple device of military aircraft radio from. So that communication could be prevented.
The HAVE -QUICK program
The HAVE -QUICK program offered the solution to the existing problem. It had a favorable effect on the development engineers have the latest radios already had multi-channel frequency synthesizer, keyboard and display for data entry. To achieve the interference suppression capability to develop a timer means for accurate time synchronization, and a micro- processor to control the frequency hopping only were also required.
HAVE -QUICK - initialization
Air stations and aeronautical ground places that are supposed to work in a HAVE -QUICK - spark circuit are to initialize with the exact time of day, which is usually generated by a GPS receiver. Furthermore, the valid key password and the required network number must be entered. So that the user in question is assigned the required access authorization to a particular network, network group or user mode.
Days key and network number to generate sequences, which in turn control the changes of the individual frequency channels, that is, the frequency hopping.
SATURN
HAVE QUICK was widespread in the late twentieth century. Since about 2005, the system is used in almost all U.S. military aircraft, but also largely used in which the NATO air forces. The system constant obsolescence and improvements addition subject. Examples include HAVE QUICK II Phase 2 and the second-generation devices under the name Second Generation Anti -Jam Tactical UHF Radio for NATO ( SATURN ). The latter are fully programmable and far more complex frequency -hoppers and a group possess higher resistance to Electronic Counter Measures (ECM).
SATURN is fully backward compatible to all modifications of HAVE QUICK, also uses the 225-400 MHz frequency for which availability is to harmonized NATO -wide UHF band.
Utilization line
The WaSysKdo Lw is responsible for the HAVE -QUICK - utilization line. There also obsolescence management, configuration control and commissioning performed software maintenance / software change.
Special
- National air forces usually work in a common network group. In the past, there were certainly variations to this scheme: Thus, the HAVE -QUICK - users of the German Air Force for example, were summarized in northern Germany, in subordination to the Second Allied Tactical Air Force in network group 1, while the southern part, together with the Fourth Allied Tactical Air Force network group 2 belonged.
- The coordination of frequency channels for HAVE QUICK UHF band, the design of the so-called hop sets, carried out primarily in NATO Europe through NATO Allied Radio Frequency Agency ( ARFA ) in Brussels.
- For training and exercise purposes, HAVE QUICK operate in peace mode with reduced use of spectrum. In operation mode, these restrictions are lifted. Four -line numbers can be used across networks in network group 1 and group 2 network.
- HAVE QUICK is no encryption or crypto system, but some HAVE -QUICK - stations are compatible crypto device such as the KY -58 VINSON family.
