The Global Positioning System (GPS) is a U.S. space-based global navigation satellite system. It provides reliable positioning, navigation, and timing services to worldwide users on a continuous basis in all weather, day and night, anywhere on or near the Earth which has an unobstructed view of four or more GPS satellites. GPS is made up of three segments: Space, Control and User.
MISTRAM (MISsile TRAjectory Measurement) was a high-resolution tracking system used by the United States Air Force to provide highly detailed trajectory analysis of rocket launches. A "classic" ranging system used since the 1960s uses radar to time a radio signal's travel to a target (in this case, the rocket) and back. This technique is accurate to approximately 1%.
An Inertial Navigation System (INS) is a navigation aid that uses a computer, motion sensors and rotation sensors to continuously calculate via dead reckoning the position, orientation, and velocity (direction and speed of movement) of a moving object without the need for external references. It is used on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft.
A wire-guided missile is a missile that is guided by signals sent to it via thin wires connected to both the missile and its guidance mechanism, which is located somewhere near the launch site. As the missile flies, the wires are reeled out behind it. This guidance system is most commonly used in anti-tank missiles, where its ability to be used in areas of limited line-of-sight make it useful, while the range limit imposed by the length of the wire is not a serious concern.
SACLOS (short for Semi-Automatic Command to Line of Sight) is a second-generation method of missile guidance. In SACLOS, the operator has to continually point a sighting device at the target while the missile is in flight. Electronics in the sighting device and/or the missile then guide it to the target. There are two common ways SACLOS can work:
MCLOS (short for Manual Command to Line of Sight) is a first-generation 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.
Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its "Single Shot Kill Probability" (SSKP). These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active," "passive" and "preset" guidance.
A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser guided bombs, missiles, or precision artillery munitions, such as the Paveway series of bombs, Lockheed-Martin's Hellfire, or the Copperhead round, respectively. When a target is marked by a designator, the beam is invisible and does not shine continuously. Instead, a series of coded pulses of laser-light are fired.
Beam-riding, also known as beam guidance, is a technique of directing a missile to its target by means of radar or a laser beam. It is one of the simplest forms of guidance using radar or lasers. The main use of this kind of system is to destroy airplanes or tanks. First, an aiming station (possibly mounted in a vehicle) in the launching area directs a narrow radar or laser beam at the enemy aircraft or tank.
Fire-and-forget is a third-generation method of missile guidance. The military use the term for a type of missile which does not require further guidance after launch such as illumination of the target or wire guidance (TOW), and can hit its target without the launcher being in line-of-sight of the target.
Jones Lake State Park is a North Carolina state park in Bladen County, North Carolina in the United States in near Elizabethtown. It covers 2,208 acres (9 km²) and includes the natural Carolina bay lakes of Jones Lake and Salters Lake. Jones Lake State Park is north of Elizabethtown on North Carolina Highway 242 in North Carolina's Coastal Plain region.
