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.
Guidance, navigation and control (abbreviated GNC, GN&C, or G&C) is a branch of engineering dealing with the design of systems to control the movement of vehicles, especially, automobiles, ships, aircraft, and spacecraft. In many cases these functions can be performed by trained humans.
The main disadvantage of both SACLOS guidance systems in an anti-tank role is that working on angular differences evaluation, it does not allow any notable separation between guidance system and missile launch post the opposite of manual command to line of sight (MCLOS) ones, thus allowing updated version of such anti-tank weapons (notably AT-3 ...

These guidance systems usually need the use of radars and a radio or wired link between the control point and the missile; in other words, the trajectory is controlled with the information transmitted via radio or wire (see Wire-guided missile). These systems include: Command guidance – The missile tracker is on the launching platform. These ...

In October 1999, the Corps of Engineers established a system of laboratories, called the Engineer Research and Development Center (ERDC). [2] The ERDC was a consolidation of seven, pre-existing laboratories: the Coastal and Hydraulics, Environmental, Geotechnical and Structures, and Information Technology Laboratories in Vicksburg, Mississippi; the Construction Engineering Research Laboratory ...
