Data Validation and Adjustmentoftware design can permit automatic detection and/or correction of many types of data errors and mitigate time-consuming and costly manual data correction. For real-time operation, automatic correction or deletion of bad data is essential because of the time required for manual processing.

Geometrical Basis of Attitude Determinationled in a manner appropriate for attitude determination. In Part III we describe the procedures by which these data are processed to determine the spacecraft attitude. Chapter 10 introduces the types of attitude measurements and the geometrical meaning of these measurements. Chapters 11 and 12 descri

Evaluation and Use of State EstimatorsThis chapter discusses practical aspects of state estimation and makes specific suggestions for the evaluation and operational use of estimators. There is no optimum procedure for analyzing attitude data, and much of the discussion is necessarily subjective. This chapter is intended as a practical g

Evaluation and Use of State Estimatorstimation and procedures for determining which state vector elements should be solved for in a particular situation. Although the discussion is as spacecraft independent as possible, the examples used are drawn primarily from systems using horizon sensors and Sun sensors on a spinning spacecraft, such as the CTS spacecraft described in Section 1.1.

Book 1978 work has been done for many years in the areas of attitude determination, attitude prediction, and attitude control. During this time, it has been difficult to obtain reference material that provided a comprehensive overview of attitude support activities. This lack of reference material has made i
