Decentralized Estimation Algorithms for Formation Flying Spacecraft
Several space missions are being planned with large fleets of spacecraft at GEO and beyond where relative navigation using GPS will either be impossible or insufficient. Onboard local ranging devices will be required to replace or augment the available GPS measurements to perform relative navigation for these missions. The vast amounts of distributed data and the computational load limitations ...
متن کاملGPS Sensing for Spacecraft Formation Flying
Carrier-phase Di erential GPS (CDGPS) for orbit and attitude determination is emerging as a very promising low cost alternative to more conventional methods, such as sun sensors, magnetometers, and star trackers. Relative spacecraft position and attitude determination are important for missions involving formation ying, such as those proposed for stellar interferometry under NASA's New Millenni...
متن کاملMission Performance Measures for Spacecraft Formation Flying
Clusters of low-performance spacecraft flying in formation may provide enhanced performance over single high-performance spacecraft. This is especially true for remote sensing missions where interferometry or stereographic imaging may provide higher resolution data. The configuration of such formations vary during an orbit due to orbital dynamics, and over larger time scales due to perturbation...
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...
