Errors
Dead reckoning may give the best available information on position, but is subject to significant errors due to many factors as both speed and direction must be accurately known at all instants for position to be determined accurately. For example, if displacement is measured by the number of rotations of a wheel, any discrepancy between the actual and assumed diameter, due perhaps to the degree of inflation and wear, will be a source of error. As each estimate of position is relative to the previous one, errors are cumulative.

Famous quotes containing the word errors:
“There are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence. The other is to believe, and to feel an excessive and unhealthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight.”
—C.S. (Clive Staples)
“Here among the mountains the pinions of thought should be strong, and one should see the errors of men from a calmer height of love and wisdom.”
—Ralph Waldo Emerson (1803–1882)
“Repent, repent, and from old errors turn!’
Who listened to his voice, obeyed his cry?
Only the echoes, which he made relent,
Rung from their marble caves ‘Repent! Repent!’”
—William Drummond, of Hawthornden (1585–1649)
