Detailed Text For Service: Architecture

Arrowhead System Engineering offers expert consulting relating to sensors and effectors relating to momentum control of satellites.

Services include establishing sizing and performance requirements for inertial measurement, star trackers, sun sensor, reaction wheels, and Control Moment Gyroscopes (CMGs). Included in this knowledge base is a detailed understanding of singularity sizing and singularity avoidance. Also provided is a years of experience with induced vibration, balance, and bearing performance. Also included in Momentum Control expertice is control law implementation from performance requiremens, to functional requirements, to architectural implementation. A working knowelege of control bandwidth to sampling rate along with impact of delay and jitter on control phase margin is available.

A detailed understanding of the inner workings of Reaction Wheel Assembly (RWA) and Control Moment Gyroscope (CMG) hardware and their associated performance is provided with over fifteen years of work with these devices. Specific accomplishments while working this business segment include:
