A modular scheme for generating attitude reference motions is presented. This scheme is a generic strategy to develop the guidance profile for a wide range of mission scenarios through combination of atomic guidance modules that fulfill a well-defined functionality. There are three core functionalities that conform all guidance reference motions: base pointing reference, dynamic reference, and attitude offset. The base pointing functionality encompasses a fixed pointing requirement, for instance inertial pointing, orbit Hill-frame pointing, orbit velocity-frame pointing, or constrained two-body pointing. The dynamic reference functionality defines a dynamic reference motion relative to the base pointing reference, for instance relative fixed spinning or relative scanning. Finally, an attitude offset can be added to the composed reference to account for the requirement of controlling a spacecraft-fixed frame that is not the main body frame. For each one of these functionalities, different software guidance modules are implemented and showcased; the mathematical equations are developed, and numerical simulations illustrate how the individual components are arranged to support different rotational dynamics mission requirements.
