Proportional navigation (also known as PN or Pro-Nav) is a guidance law (analogous to proportional control) used in some form or another by most homing air target missiles. [1] It is based on the fact that two vehicles are on a collision course when their direct line-of-sight does not change direction as the range closes. PN dictates that the ...
Proportional navigation (also known as "PN" or "Pro-Nav") is a guidance principle (analogous to proportional control) used in some form or another by most homing air target missiles. [5] It is based on the fact that two objects are on a collision course when the direction of their direct line-of-sight does not change.
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 aircraft behaves as in direct mode: the autotrim feature is turned off and there is a direct response of the elevators to the sidestick inputs. The horizontal stabilizer is set to 4° up but manual settings (e.g. for center of gravity) override this setting.
Litton Systems Inc., or Litton Industries, the Guidance and Control Systems Division at Beverly Hills CA, were one of the major producers of inertial systems in the US in the 1950s and 1960s, and have made a series of systems for a number of American aircraft. [5] The Genesis of inertial navigation systems is explained in the following reference.
The output of the navigation system, the navigation solution, is an input for the guidance system, among others like the environmental conditions (wind, water, temperature, etc.) and the vehicle's characteristics (i.e. mass, control system availability, control systems correlation to vector change, etc.).
Electronic Route Guidance System (ERGS) was an American government-sponsored in-vehicle navigation and guidance system developed by the United States Federal Highway Association in the 1970s. [1] ERGS was the initial stage of a larger research and development effort called the Intelligent Transportation System (ITS).
