ON-AXIS precise pointing and tracking systems were developed to provide high resolution optical imagery of missile and satellite targets. They consist of specially designed mounts for radar or laser active sensors with boresight optics to calibrate the mount to the celestial sphere at multiple points. With sources of error constrained to predetermined limits or modeled, the computerized system accepts observational data to generate highly accurate real time state vectors in digital adaptive control loops con-verging to the actual sta a of the vehicle in geocentric space. Large (48 inch aperture) remote electro-optical systems are driven by the state vector providing smooth tracking and high resolution (to a few feet) images of ballistic missiles and near earth satellites. Synchronous and other deep space objects are detected as point sources however major events such as thrusting are monitored by observing large scale phenomena associated with the rocket motor plume. Results of data obtained from tests will be presented.
