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:
“But the nomads were the terror of all those whom the soil or the advantages of the market had induced to build towns. Agriculture therefore was a religious injunction, because of the perils of the state from nomadism.”
—Ralph Waldo Emerson (1803–1882)
