This paper is mainly based on the Space Sun Telescope Satellite and detailedly analyzes the gravity gradient torque which acts on the satellite while it is on orbit.

Genetic algorithm for optimal large angle maneuvers of gravity gradient stabilized micro-satellites;

This paper consideres a liquid filled satellite with a flexible gravity gradient boom, the attitude dynamics equations are obtained using a beam with tip mass as well as the equivalent mechanical model of liquid sloshing, which consists of a group of ball pendulums and an axial symmetry disk.

In order to satisfy the requirement of attitude control system design for gravity gradient stabilized satellite, this paper presents the coupling dynamics equations of satellite attitude and gravity gradient boom deployment.

Because the gravitation difference brings the earth satellite the gravitation gradient moment it has a effect on the earth satellite s attitude satbillization while the earth satellite being on the track.

Status and prospects of gravity gradiometers;

Based on the gravity gradient measurement principle of rotating accelerometer gravity gradiometer,an online method of accelerometers scale factor adjusting is proposed in this paper.

The observation and compensation schemes of drift of platform inertial navigation system are studied by using genetic algorithm (GA), Kalman filter and rotating accelerometer gravity gradiometer.
