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:
“The weak have one weapon: the errors of those who think they are strong.”
—Georges Bidault (1899–1983)
“Let us pardon him his hope of a vain apocalypse, and of a second coming in great triumph upon the clouds of heaven. Perhaps these were the errors of others rather than his own; and if it be true that he himself shared the general illusion, what matters it, since his dream rendered him strong against death, and sustained him in a struggle to which he might otherwise have been unequal?”
—Ernest Renan (1823–1892)
“Science in the modern world has many uses; its chief use, however, is to provide long words to cover the errors of the rich.”
—Gilbert Keith Chesterton (1874–1936)
