Geometrical Basis of Attitude Determinationbe methods for combining as many measurements as there are observables (usually two or three) to produce a single, possibly multivalued determination of the attitude. Chapters 13 and 14 then describe filtering methods to provide optimum estimates of the attitude, given many data points.

Modeling the Earthas a point source of light or as a uniformly illuminated disk. In contrast, the Earth as seen from nearby space has a relatively complex appearance, at least some aspects of which must be modeled for accurate attitude determination.

Modeling the Space Environment environment that are relevant to attitude determination and control. Sections 5.1 and 5.2 describe the magnetic and gravitational fields of the Earth, although many of the modeling procedures can be extended to other planets as well. Section 5.3 discusses the interplanetary medium known as the sola

Attitude Hardwarere experimentation has taken place over the 20-year history of spaceflight. Although this experimentation and development is still continuing, a variety of basic functional types of attitude hardware have emerged. This chapter describes the physical characteristics and operating principles of a vari

Data Transmission and Preprocessingude determination by a software system. Section 8.1 provides an overview of the data transmission process from the spacecraft to the attitude determination software system, and the command transmission process from the ground to the spacecraft. Sections 8.2 and 8.3 provide a detailed view of two par
