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 M1156 Precision Guidance Kit (PGK), formerly XM1156, is a U.S. Army-designed precision guidance system to turn existing 155 mm artillery shells into smart weapons. [2]
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.
The various navigation templates maintained by the Military history WikiProject are all intended to be implemented through a single base template, which combines the project's common template style with the standard navigation box format.
The D-17B is a component of the NS-10Q missile guidance system for the Minuteman I, while the D-37C is a component of the NS-17 missile guidance system for the Minuteman II. There are many basic similarities between the two designs. They are both synchronous, serial machines with fixed head disks for primary memory.
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.).
