A geographical state vector is a set of data describing exactly where an object is located in space, and how it is moving. From a state vector, the object's current and future position can be determined.
A geographical state vector typically will contain seven elements: three position coordinates, three velocity terms, and the time at which these values were valid.
A state vector may be expressed in a variety of coordinate systems (e.g. the North east down coordinate system).
Famous quotes containing the word state:
“There is one consolation in being sick; and that is the possibility that you may recover to a better state than you were ever in before.”
