Predicted Line Of Sight
Predicted line of sight (PLOS) is a method of missile targeting. In PLOS, the operator tracks the target with the missile launcher's onboard sights for a short period of time (3-5 seconds). Software on the launcher extrapolates from the data gathered, producing a prediction of the route required to intercept the moving target. When fired the missile uses inertial navigation to fly this course and hopefully engage the target either by direct contact or via proximity fuse detonating the warhead. The method is used by the NLAW anti-tank weapon. For a moving vehicle, the course will be a curve, the greater the angular velocity of the target from the launcher the smaller the radius of the curve. The curve is such that if the launcher had kept tracking the target after launch the missile would always be on the line between the launcher and target. This is what is attempted by '' command to line of sight'' (CLOS) but in the case of PLOS, no commands are issued post-launch and the target is ...

NLAW
The Saab Bofors Dynamics NLAW (pronounced: ''"N-LAW"'', ), also known as the MBT LAW or RB 57, is a fire-and-forget, lightweight shoulder-fired, and disposable (single-use) line of sight (LOS) missile system, designed for infantry use. The missile uses a soft-launch system and is guided by predicted line of sight (PLOS). It can carry out an overfly top attack (OTA) on an armoured vehicle, or a direct attack (DA) on structures and non-armoured vehicles. The system was developed in Sweden by prime contractor Saab Bofors Dynamics, on behalf of the British and Swedish defence authorities who procured the system in a joint venture. It was mainly produced in the United Kingdom by Team MBT LAW UK, which included 14 subcontractors, most notably Thales Air Defence. Users of the weapon include Finland, Indonesia, Luxembourg, Malaysia, Sweden, Switzerland, Ukraine, and the United Kingdom. Etymology The name "NLAW" initially referred to the original British development programme whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command Guidance
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-and-forget
Fire-and-forget is a type of missile guidance which does not require further external intervention after launch such as illumination of the target or wire guidance, and can hit its target without the launcher being in line-of-sight of the target. This is an important property for a guided weapon to have, since a person or vehicle that lingers near the target to guide the missile (using, for instance, a laser designator) is vulnerable to attack and unable to carry out other tasks. Generally, information about the target is programmed into the missile just prior to launch. This can include coordinates, radar measurements (including velocity), or an infrared image of the target. After it is fired, the missile guides itself by some combination of gyroscopes and accelerometers, GPS, onboard active radar homing, and infrared homing optics. Some systems offer the option of either continued input from the launch platform or fire-and-forget. Fire-and-forget missiles can be vulnerable ...

Manual Command To Line Of Sight
Manual command to line of sight (MCLOS) is a method for guiding guided missiles. With an MCLOS missile, the operator must track the missile and the target simultaneously and guide the missile to the target. Typically the missile is steered with a joystick, and its path is observed through a periscope-type telescopic sight. The missiles are usually equipped with a magnesium flare in the base that automatically ignites on launch and allows the gunner to visually track the fast-moving missile in a manner similar in concept to tracer ammunition. MCLOS requires considerable training and practice to master, since even a minor disruption in the gunner's concentration would likely cause a miss. These guidance systems have marginal accuracy on tank-sized targets, even with perfect line-of-sight by the gunner, due to erratic flight paths requiring timely manual corrections. As demonstrated by the Israeli Army under fire from Soviet-armed Arab states, responding to the distinctive smoke puff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
