Guidance and Control of Formation Flying Spacecraft
2008A 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 ...

Distributed Attitude Coordination Control for Spacecraft Formation Flying
IEEE Transactions on Aerospace and Electronic Systems, 2012A distributed attitude coordination control scheme using terminal sliding mode (TSM) is proposed for a group of spacecraft in the presence of external disturbances. A novel fast terminal sliding manifold is presented, and a robust control term based on the hyperbolic tangent function is employed to suppress bounded external disturbances.

Unscented kalman filter for multiple spacecraft formation flying
Proceedings of the 2003 American Control Conference, 2003., 2004Abstract In this paper, Unscented Kalman Filter (UKF) is presented both in its canonical form and in a form that is suitable for spacecraft attitude estimation using quaternions. An atti- tude quaternion has a unit norm, resulting in a singular co- variance matrix.

Pulse-based periodic control for spacecraft formation flying
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000Distributed spacecraft formation flying has been identified as an enabling technology by NASA and the US Air Force for several future space missions. Implementation of the distributed spacecraft formation flying concept requires tight, autonomous, cooperative, real-time control of the relative distance and attitude between the participating spacecraft.

Deep Space Formation Flying Spacecraft Path Planning
The International Journal of Robotics Research, 2007Efficient algorithms for collision-free energy sub-optimal path planning for formations of spacecraft flying in deep space are presented. The idea is to introduce a set of way-points through which the spacecraft are required to pass, combined with parameterizations of the trajectories which are energy-optimal for each spacecraft.

A study of the navigation for formation flying of spacecraft
SICE Annual Conference 2007, 2007This paper presents a robust and efficient approach for relative navigation and parameter estimation of spacecraft flying in formation. This approach uses measurements from the optical data that provides a line of sight vector from the master spacecraft to the secondary satellite.

6-DOF mutual synchronization of formation flying spacecraft
Proceedings of the 45th IEEE Conference on Decision and Control, 2006In this paper we present a 6 degrees of freedom (6-DOF) synchronization scheme for a deep space formation of spacecraft. In the design, which is referred to as a mutual synchronization scheme, feedback interconnections are designed in such a way that the spacecraft track a time varying reference trajectory while at the same time keep a prescribed ...

Spacecraft formation flying: dynamics and control
Proceedings of the 1999 American Control Conference (Cat. No. 99CH36251), 1999A concept of a distributed array of small, low-cost, cooperative, and highly coordinated microspacecraft is vigorously being pursued for several future space missions. Implementation of the distributed coordinated spacecraft concept will require tight control of the relative distances and phases between the participating spacecraft. We review nonlinear
