Spin-Assisted Angles-Only Navigation and Control For SmallSats

This work analyzes the ability to estimate and control the relative position and velocity of a Small Satellite with respect to a target vehicle using a single optical camera. Although the target range is generally unobservable when using anglesonly measurements, relative position/velocity observability can be achieved when the SmallSat is slowly rotating and the camera is offset from the center of gravity. The sensitivity of the navigation errors and trajectory dispersions to several simulation parameters is discussed, including SmallSat camera offset, spin rate, and range to target. Also included in the analysis is the effect of common sensor errors (e.g. camera and gyro bias/noise), external disturbances, and initial conditions. Future efforts are mentioned to extend the analysis to cooperative/uncooperative targets and to increase analysis efficiency through Linear Covariance analysis

Dynamical systems : control and stability

Proceedings of the 13th Conference „Dynamical Systems - Theory and Applications" summarize 164 and the Springer Proceedings summarize 60 best papers of university teachers and students, researchers and engineers from whole the world. The papers were chosen by the International Scientific Committee from 315 papers submitted to the conference. The reader thus obtains an overview of the recent developments of dynamical systems and can study the most progressive tendencies in this field of science
