Inertial navigation system errors are analysed in more detail than is found in the readily available literature, particularly in respect of the long period errors. The existence is shown of oscillatory errors of three different periods 84 minutes, a nominal 24 hours and a less important Foucault period. The basic equations are essentially non-linear and this limits the scope of the analytical approach. It is hoped to attempt a more complete computer simulation of the problem later. Author
