Decentralized Relative Attitude Estimation for Three-Spacecraft Formation Flying Applications
This paper investigates the problem of relative spacecraft attitude estimation between three vehicles from a decentralized point of view. Decentralized attitude estimation is achieved through the use of local extended Kalman filters and a data fusion process known as the Covariance Intersection algorithm. Because the global attitude parameterization is the quaternion, the Covariance Intersectio...
متن کاملVision-based Relative Navigation for Formation Flying of Spacecraft
The objective of this paper is to develop a robust and efficient approach for relative navigation and attitude estimation of spacecraft flying in formation. The approach developed here uses information from a new optical sensor that provides a line of sight vector from the master spacecraft to the secondary satellite. The overall system provides a novel, reliable, and autonomous relative naviga...
متن کاملDecentralized 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 کاملStereo vision-based relative navigation algorithm for satellites formation flying
Space mission with multiple spacecraft formation is an important means to space operation. A new relative navigation algorithm based on stereo vision is developed aiming at high navigation precision requirement of spacecraft formation flying. It uses stereo vision camera attached on the tracking craft as measurement sensor, gets the relative location of target craft in the tracking craft body r...
متن کاملAnalysis of Decentralized Estimation Filters for Formation Flying Spacecraft
Future formation flying missions are being planned for fleets of spacecraft in MEO, GEO, and beyond where relative navigation using GPS will either be impossible or insufficient. To perform fleet estimation for these scenarios, local ranging devices on each vehicle are being considered to replace or augment the available GPS measurements. A previous paper presented several approaches for distri...
