Guidance and Control of Formation Flying Spacecraft
A key element of NASA’s future space exploration is high precision formation flying (FF) for space interferometry. Precision FF has never been attempted before and poses new and significant challenges to the underlying control system. While the guidance and control (G&C) methodologies of single spacecraft for traditional planetary flyby and orbiter missions are well-understood, the G&C of FF mi...
متن کاملEfficient Control of Formation Flying Spacecraft
Several upcoming European and American space missions will be operated using a number of spacecraft flying in formation. The associated scientific challenges are demanding, both with respect to the construction of the spacecraft as well as to the mission design. For instance, energy efficient trajectories and corresponding control laws that enable precision formation flying over long periods of...
متن کاملModel Predictive Control for Formation Flying Spacecraft
Formation flying is an enabling technology for many future space missions. This thesis addresses some of the key dynamics and control issues expected in future missions by pursuing two areas of advancement: extensions of relative linear dynamics models and assessment and mitigation of sensor noise effects on control systems. Relative dynamics models play an important role in finding drift-free ...
متن کاملAttitude Tracking Control for Spacecraft Formation Flying
We develop a non-linear tracking control law to be applied to formation flying spacecraft. Each spacecraft in the formation is modeled as a rigid body with N axisymmetric wheels controlled by axial torques, and the kinematics are represented by Modified Rodriques Parameters (MRPs). The paper first derives the open-loop reference attitude, rate, and acceleration commands for tracking a moving ob...
متن کاملGVE-Based Dynamics and Control for Formation Flying Spacecraft
Formation flying is an enabling technology for many future space missions. This paper presents extensions to the equations of relative motion expressed in Keplerian orbital elements, including new initialization techniques for general formation configurations. A new linear time-varying form of the equations of relative motion is developed from Gauss’ Variational Equations and used in a model pr...
