# Optimal Estimation Methods

### From ANCS Wiki

This course serves to teach traditional concepts and recent advances in estimation, and to relate these concepts to modern dynamic systems found in aerospace disciplines. This course stresses modeling of physical problems into mathematical terms. Examples will be given from both spacecraft and aircraft systems.
