ACS Without an Attitude

This book de-emphasizes the formal mathematical description of spacecraft on-board attitude and orbit applications in favor of a more qualitative, concept-oriented presentation of these topics. The information presented in this book was originally given as a set of lectures in 1999 and 2000 instigated by a NASA Flight Software Branch Chief at Goddard Space Flight Center.  The Branch Chief later suggested this book.  It provides  an approachable insight into the area and is not intended as an essential reference work.
