Strapdown Inertial Navigation System of Minimum Dimension (3D oscillator as a complete inertial sensor)

We consider two implementations of an isotropic oscillator to be used in the construction of a strapdown inertial system of new type [1]. The first implementation is a contact-free suspension of an electrically conductive ball used in electrostatic gyros, and the second implementation is a 3D combination of elastic constraints holding a mass point. The inertial system of a new type has the minimum possible dimension. It differs from the already known (platform and strapdown) inertial systems in that it permits one to do without gyros and Poisson integrators because it also performs the functions of an apparent acceleration transducer.
