Written for graduate students and aerospace professionals, this e-book is a reference covering the latest advances in spacecraft attitude and orbit control. Additional topics covered include formation flying, orbit and attitude estimation, and the spacecraft design process. The second edition includes a...
Modelling and simulation of spacecraft dynamics play a central role in the development process for spacecraft control systems. In particular, while the requirements for attitude and orbit control systems are becoming more and more stringent, there is also a need for adequate design tools in order ...

In these missions, the spacecraft takeover control will be a critical technology. The service spacecraft will take over attitude and orbit control functions with a surrogate control system for the target spacecraft, allowing the target to continue to operate the other functions on the communication...

This paper deals with the analysis and the control of the attitude dynamics of low earth orbit (LEO) satellites with large magnetic residual dipoles. The state dependent nature of the interaction of the spacecraft with the Earth's magnetic field is addressed and a model of the attitude dynamics...
of functions. One function performed is to precess attitude by timing chemical thruster pulses relative to an inertial reference, such as the sun or earth. Such body-fixed chemical thrusters have been used to control the spin rate and attitude of a spacecraft during thrusting for orbit raising....
Many current satellites employ on-off thrusters to accomplish attitude control tasks which may include initial acquisition, rotational maneuvers, and on-orbit stabilization. This work shows that the use of pulse-width pulse-frequency (PWPF)-modulated thrusters provides several important advantages over co...
A spacecraft attitude control system includes a Momentum Wheel Assembly (MWA) or a Reaction Wheel Assembly (RWA), containing a spinning flywheel, mounted by the use of a mounting bracket to a rotary g
