Abstract : The perturbation equations, which describe the behavior of an ideal inertial navigation system resulting from small departures from the equilibrium position, are derived for all combinations of the simplest possible assumptions concerning both the inertial navigation system and the figure of the earth, including at least one case of practical importance. A feature common to all cases is found to be the existence of an oscillation with a period of twentyfour hours. It is also shown that, under certain sets of assumptions, the oscillation with twentyfour hour period may exist when the errors are not necessarily small. (Author)
