Stereo 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 کاملRelative State Estimation of Satellite Formation Flying Using Kalman Filter
In this paper, an approach is proposed for relative state estimation for satellites in formation flying. To estimate the relative states of two satellites, the Kalman Filter algorithms (EKF, UKF) are adopted with the relative range and range rate between two satellites and attitude of a satellite as measurement variables. In case that the initial state and measurements errors are moderate, both...
متن کاملDecentralized 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 کاملDevelopment of a Spaceborne GPS Receiver for Precise Relative Navigation of Formation Flying Small Satellites
Use of the differential carrier phase measurements of the Global Positioning System (GPS) can achieve centimetre-level accuracy thus it can be applied to the relative positioning in formation flying missions. This paper describes the development of a spaceborne GPS receiver upon the UNSW’s Namuru GPS receiver, which is built on the field of field programmable gate array (FGPA). Operating a GPS ...
متن کاملRadio-frequency sensor fusion for relative navigation of formation flying satellites
The increasing need for robustness, reliability and flexibility of relative navigation systems imposed by the current and future autonomous formation flying missions, calls for the implementation of solutions using an alternative approach to single-sensor systems. These schemes possess different levels of availability, mainly driven by sensor failure and mission orbit profiles. The data obtaine...
