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:
“A happy people I call them still, whose peace and genuine morals have not been contaminated with European vices; and whose errors are only the errors of ignorance, and not the rooted depravity of a pretended civilization, and a spurious and mock Christianity.”
—J.G. (John Gabriel)
“[Montesquieu] lifted the veil from the venerable errors which enslaved opinion, and pointed the way to those luminous truths of which he had but a glimpse himself.”
—James Madison (1751–1836)
“When a Man is in a serious Mood, and ponders upon his own Make, with a Retrospect to the Actions of his Life, and the many fatal Miscarriages in it, which he owes to ungoverned Passions, he is then apt to say to himself, That Experience has guarded him against such Errors for the future: But Nature often recurs in Spite of his best Resolutions, and it is to the very End of our Days a Struggle between our Reason and our Temper, which shall have the Empire over us.”
—Richard Steele (1672–1729)
