Relative location, a location as described by where it is compared to something else. For example, Albany, New York is roughly 140 miles north of New York City. Every site on Earth has a unique absolute location, which can be identified with a reference grid (such as latitude and longitude).
An icon representing the concept of location. In geography, location or place is used to denote a region (point, line, or area) on Earth's surface.The term location generally implies a higher degree of certainty than place, the latter often indicating an entity with an ambiguous boundary, relying more on human or social attributes of place identity and sense of place than on geometry.
The transmitters emit ultrasonic waves in sequence toward the three receivers, which can then be used to derive spatial data on the three transmitters using the methods described above. The device's orientation can then be derived based on the known positioning of the transmitters upon the device and their spatial locations relative to one another.
The preferred frame of reference is the relative one. Languages that rely largely on absolute frame of reference include many Australian aboriginal languages (e.g., Arrernte, Guugu Yimithirr) and some Mayan languages (e.g., Tzeltal). In Guugu Yimithirr, there is no way to say "The cat is to the left of the house," and the only way to describe ...
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; Eddy-current sensor; Hall effect sensor; Inductive sensor
Because every technology has its pros and cons, most systems use more than one technology. A system based on relative position changes like the inertial system needs periodic calibration against a system with absolute position measurement. Systems combining two or more technologies are called hybrid positioning systems. [16]

Absolute motion is the translation of a body from one absolute place into another: and relative motion, the translation from one relative place into another ... — Isaac Newton These notions imply that absolute space and time do not depend upon physical events, but are a backdrop or stage setting within which physical phenomena occur.
