Abstract— In response to the interest to re-use Palapa B2R satellite nearing its End of Life (EOL) time, an idea to incline the satellite orbit in order to cover a new region has emerged in the recent years. As a prolate dual-spin vehicle, Palapa B2R has to be stabilized against its internal energy dissipation effect. This work is focused on analyzing the dynamics of the reusable satellite in i...

The Satellite Navigation and Positioning (SNAP) group at The University of New South Wales has been conducting research into high precision attitude determination using a multi-antenna single-frequency GPS array, aided by low grade angular rate gyros. The objective of the research is to develop an accurate, reliable attitude sensor solution at an affordable cost which can be implemented on UAVs...

In this paper, a finite-time control scheme is presented for stabilization of the satellite chaotic attitude around its equilibrium point when its attitude is confused by a disturbed torque. Controllers and settling time of stabilizaton are obtained, based on the Lyapunov stability theorem and finite-time control scheme. This method is satisfied for any initial condition. Numerical simulations ...

This paper presents an anlysis based on the momentum conservation equations of a redundant free-flying spacecraft/manipulator system, acting in zero-gravity environment. In order to follow a predefined end-effector path, the inverse kinematics at velocity level is considered. The redundancy i solved alternatively in terms of pseudoinverses and null-space components of the manipulator inertia ma...
