The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg). [1] These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active", "passive", and "preset" guidance.
Track-via-missile or TVM refers to a missile guidance technique which combines features of semi-active radar homing (SARH) and radio command guidance. This avoids the problems with terminal accuracy normally seen by command guided missiles, especially at long range.
Since so many types of missile use this guidance system, they are usually subdivided into four groups: A particular type of command guidance and navigation where the missile is always commanded to lie on the line of sight (LOS) between the tracking unit and the aircraft is known as command to line of sight (CLOS) or three-point guidance.
Beam riding is one of the simplest methods of missile guidance using a radar. It was widely used for surface-to-air missiles in the post-World War II era for this reason. An early example was the British Brakemine, first tested in 1944, as was the first commercially available SAM, the Oerlikon Contraves RSA.
The self-contained system finally prevailed in ballistic missile applications for obvious reasons. In space exploration, a mixture of the two remains. In the summer of 1952, Dr. Richard Battin [ 8 ] and Dr. J. Halcombe ("Hal") Laning Jr. , researched computational based solutions to guidance as computing began to step out of the analog approach.
can someone explain the difference between preset and inertial guidance?-- Arado ( talk ) 12:20, 12 February 2015 (UTC) [ reply ] A torpedo can be preset to travel in a certain direction, or even travel for a certain period and then turn, but if it takes inertial guidance to compensate for unanticipated water currents that could otherwise drag ...
Missile guidance — methods for in-flight guidance of guided missiles, after they have been launched. Subcategories. This category has only the following subcategory. W.
Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object relative to a known starting point, orientation and velocity.
