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:
“Most of the folktales dealing with the Indians are lurid and romantic. The story of the Indian lovers who were refused permission to wed and committed suicide is common to many places. Local residents point out cliffs where Indian maidens leaped to their death until it would seem that the first duty of all Indian girls was to jump off cliffs.”
