Attitude Control Systems Engineering Branch (Code 591)

Mission

The Attitude Control Systems Engineering Branch (ACSEB) is the source of attitude control system expertise and will provide analysis and design and leadership in the integration of analysis, hardware, and software disciplines into flightworthy GN&C systems. The branch provides analytic expertise for all attitude systems. The Branch creates and maintains state-of-the-art analysis tools for attitude control systems, attitude determination, and sensor calibration. The Branch assesses by analysis and simulations the stability, robustness, and performance of attitude control systems for spacecraft systems.

It also serves as the focus of systems-level efforts related to guidance, navigation, and control systems within the MESA Division. As such, the branch will be the initial point of contact and primary interface for customers requiring GN&C engineering services. Conceptual designs of attitude control systems will be created and evaluated by analysis and simulation. A primary function of the branch is to ensure the training and development of engineers with a high level of systems engineering expertise in anticipation of the future needs of GSFC.
