1. A system for controlling inertia of an object comprising:

  • an inertial platform;

    an inertial measurement unit coupled to said inertial platform, said inertial measurement unit comprising a z-axis gimbal, an x-axis gimbal, and a y-axis gimbal, whereby a first flexure accelerometer and a second flexure accelerometer are coupled to said z-axis gimbal, a third flexure accelerometer and a fourth flexure accelerometer are coupled to said x-axis gimbal, and a fifth flexure accelerometer and a sixth flexure accelerometer are coupled to said y-axis gimbal;

    a processor leveling said platform perpendicular to a local gravity vector, said processor computing a spatial gravity vector with respect to said platform as a function of first gimbal angles whereby said x-, y-, and z-axis gimbals experience maximum forces, said processor controlling said gimbals such that an xz-plane, formed as a function of an intersection of axes of rotation of said x- and z-axis gimbals, is perpendicular to said local gravity vector, said processor further rotating said platform about a z-axis and recording a second gimbal angle wherein a maximum positive force vector is generated, thereby establishing an east-west vector, and said processor recording said first gimbal angles and said second gimbal angle.
