Abstract

An optimal online pp-based estimator for the guidance states of a short range homing system is presented, taking into account : the horning head measurement errors, autopilot measurement errors, launch initial heading errors, and wind disturbances. A powerful 16-bit microprocessor system is used. The obtained results illustrate the potential improvement of both the missdistance and normal acceleration as well as the overall system performance. Moreover, the system allows for further modifications through more powerful algorithms.
