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:
“My errors are by now natural and incorrigible; but the good that worthy men do the public by making themselves imitable, I shall perhaps do by making myself evitable.”
—Michel de Montaigne (1533–1592)
“In faith I do not love thee with mine eyes,
For they in thee a thousand errors note,
But ‘tis my heart that loves what they dispise,”

“I shall do less whenever I shall believe what I am doing hurts the cause, and I shall do more whenever I shall believe doing more will help the cause. I shall try to correct errors when shown to be errors; and I shall adopt new views so fast as they shall appear to be true views.”
