The basic of guidance and navigation

Part of the Springer Praxis Books book series (PRAXIS)

Alone by itself, the computer is blind to the world around it, lacking the most basic information on orientation and the accelerations that the spacecraft undergoes. Without a source for this data, the AGC’s role of guidance computer is invalidated. Two additional components are necessary for a completely integrated guidance, navigation and control package: an Inertial Measurement Unit (IMU) to provide both attitude and acceleration data, and an optics system to initialize the platform and perform navigation fixes using stellar observations.
