An absolute bearing is measured with a bearing compass. The measurement of absolute bearings of fixed landmarks and other navigation aids is useful for the navigator because this information can be used on the nautical chart together with simple geometrical techniques to aid in determining the position of the vessel.
A positioning system is a ... A system based on relative position changes like the inertial system needs periodic calibration against a system with absolute position ...
The Global Positioning System (GPS), ... Many civilian applications use one or more of GPS's three basic components: absolute location, relative movement, and time ...
A position sensor is a sensor that detects an object's position. A position sensor may indicate the absolute position of the object (its location) or its relative position (displacement) in terms of linear travel, rotational angle or three-dimensional space. Common types of position sensors include the following: Capacitive displacement sensor
Absolute encoders give an absolute position value. Incremental encoders count movement rather than position. With detection of a datum position and the use of a counter, an absolute position may be derived. The position may be measured as either linear or angular position Linear encoder, converts linear position to an electronic signal
GPS/INS is commonly used on aircraft for navigation purposes. Using GPS/INS allows for smoother position and velocity estimates that can be provided at a sampling rate faster than the GPS receiver. This also allows for accurate estimation of the aircraft attitude (roll, pitch, and yaw) [citation needed] angles.
In general the position and orientation in space of a rigid body are defined as the position and orientation, relative to the main reference frame, of another reference frame, which is fixed relative to the body, and hence translates and rotates with it (the body's local reference frame, or local coordinate system).
a touch screen is a direct, absolute, isometric, position-control input device with two or more degrees of freedom (x, y position and optionally pressure) and two states (out of range, dragging). a joystick is an indirect , relative , elastic , rate-control , translational input device with two degrees of freedom (x, y angle) and two states ...
