Radiodetermination
Encyclopedia
As defined by FS-1037C, radiodetermination is the determination of the position
, velocity
or other characteristics of an object, or the obtaining of information relating to these parameter
s, by means of the propagation

There are two main fields to radiodetermination:
Positioning
Positioning may refer to:* Positioning , creating an identity in the minds of a target market* Positioning , reader context* Positioning , a technology to approximate where a mobile phone temporarily resides...
, velocity
Velocity
In physics, velocity is speed in a given direction. Speed describes only how fast an object is moving, whereas velocity gives both the speed and direction of the object's motion. To have a constant velocity, an object must have a constant speed and motion in a constant direction. Constant ...

- radiolocationRadiolocationRadiolocating is the process of finding the location of something through the use of radio waves. It generally refers to passive uses, particularly radar—as well as detecting buried cables, water mains, and other public utilities. It is similar to radionavigation, but radiolocation usually...
