Command guided - Wikipedia, the free encyclopedia Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio (or possibly through a wire connecting the missile to the launcher) and tell the missile where to steer in order to intercept its target. Pure command guidance is not normally used in modern SAM systems since it is too inaccurate during the terminal phase (when the missile is about to intercept the target). Track-via-missile is a variation of command guidance, the main difference being that the missile itself sends target tracking information back to the guidance system to aid it in calculating the intercept. en.wikipedia.org /wiki/Command_guided   (584 words)

Chapter 15 Guidance and Control In command guidance, missile steering commands are computed at the launch point using target position and missile position data derived from launch point sensors. A missile could be guided in a preset path against a fixed target; the joint effect of missile power and gravity would then cause the path to become a curve. Guided missile paths may be classified as either preset or variable. www.fas.org /man/dod-101/navy/docs/fun/part15.htm   (7052 words)

Regulus America's First Sea-borne Nuclear Deterrent   (Site not responding. Last check: 2007-10-19) Loon’s nominal range under command guidance was approximately 50 nautical miles, but using a second submarine as a relay, it could be effective out to 135 nautical miles, with a reported Circular Error Probable (CEP) of 6,000 yards. The weapon was command-guided, initially out to the radar horizon by superimposing steering commands onto the launch platform’s tracking radar waveform, and then by using a relay submarine nearer the target to track and steer the missile to the final aim point. A Regulus I is being pre-flighted on its launcher for a land-based test by Guided Missile Group TWO personnel — one of the two JATO units is clearly visible at the rear. www.chinfo.navy.mil /navpalib/cno/n87/usw/issue_11/regulus.html   (2358 words)

[No title] Unlike Linux command-line utilities, which contain their own argument parsers and output format mechanisms, MSH commands (called Cmdlets) all inherit a single base class, which ensures that all commands expose the same methods, parse arguments the same way, and output data with the same standard MSH output framework. In MSH, command output is typically a textual representation of an instance or collection of instances. Each of those columns represents a variable of the command class and it is possible to extract those variables from individual command instances. arstechnica.com /guides/other/msh.ars/2   (1044 words)

End of Posse Comitatus: Commandos Get Duty on U.S. Soil Spokesmen for the Northern Command in Colorado Springs and the Special Operations Command in Tampa, Fla., the parent organization of the Joint Special Operations Command, declined to comment on the plan, the units involved and the mission. Joint Special Operations Command (JSOC) is officially described as a "joint headquarters designed to study special operations requirements and techniques; ensure interoperability and equipment standardization; plan and conduct joint special operations exercises and training; and develop joint special operations tactics" but this description is economical with the truth. These tools allow military planners to sketch out plans against a time-line or with a map or image in the background, merge plans from other teams that are connected to the network, de-conflict and coordinate changes as plans solidify, and then use these same tools to track the progress of the battle during mission execution. www.infowars.com /articles/ps/commandos_duty_on_us_soil.htm   (2625 words)

The main sustainer rocket motor then cuts and the missile is command guided to the intercept point where the proximity fuse is triggered. The method of engagement is semi-automatic, radar to command line-of-sight, with the gunner tracking the target using the roof-mounted stabilized optical sight. www.galope.com /mike/sam_info.htm   (8065 words)

VB Series For "normal" targets, however, the VB-1 was actually not as good as unguided free-fall bombs, because a bomber could not break away immediately after dropping the bomb, and the accuracy was effectively not increased because of the lack of range control. Although in theory a whole group of bombs using the same command channel could be controlled simultaneously, this was not practical. However, the VB-5 was not command guided but used an autonomous light contrast seeker. www.designation-systems.net /dusrm/app1/vb.html   (1193 words)

TIME.com: France "Fighting for The Same Cause" -- Mar. 11, 1991 -- Page 1 During the countdown to hostilities, President Francois Mitterrand had courted British and American anger by launching an eleventh- hour peace proposal that would have handed Saddam Hussein a diplomatic victory by rewarding an Iraqi withdrawal with the convening of a Middle East peace conference. Guided by U.S. AWACS aircraft, French pilots flew their Jaguar fighter-bombers on combat missions deep into Iraqi territory, while French ground forces, including Foreign Legion units, committed themselves wholeheartedly to the battle. Overflights of France by U.S. B-52 bombers on their way to Iraq were promptly permitted, as was the big planes' refueling at a French air base. www.time.com /time/magazine/article/0,9171,972488,00.html   (695 words)

Modern Air Defense Concepts Effective air defense is based on an integrated and coordinated approach including airborne (AEW or tethered radars), active and passive ground based sensors (radar, IR scanners, ESM), command centers and "shooters" of various types. Each of these elements utilizes typical weapon systems, sensors and command and control facilities designed to meet the specific environmental and tactical scenario. With these missiles, advanced VSHORAD systems evolved during the late 1980s and 1990s, offering means of autonomous escort for mobile forces, protecting primarily from direct attack by attack helicopters and close air support assets. www.defense-update.com /features/du-2-04/modern-SHORAD.htm   (431 words)

Roland The first guided launch of a Roland prototype succeeded in June 1968.
