A Study for Semi-passive Gravity Gradiei'jt Stabilization of Small Satellites
نویسنده
چکیده
This paper gives the results of a dynamical analysis of the Globesat gravity gradient stabilized satellite in a 500 km circular orbit. The linearized equations of motion are developed and the stability of the satellite is investigated. The satellite is equipped with magnetic torquers for the purpose of providing attitude correction torques. These correction torques can be used to effect large changes in orientation and for producing small impulses for damping residual librational motions. The analysis shows that such a satellite can be captured into a gravity gradient stabilized mode, and that residual motions can be damped to small steady state values.

Passive stabilization methods for satellites have undergone extensive research and development. Recently the number of small satellites (satellites less than I 00 kg.) has increased dramatically. This has lead to increased use of passive stabilization methods, such as gravity-gradient The core of a gravity-gradient stabilization system is a deployable boom with a damping mechanism. Traditionall...
متن کاملStabilization and Walking Control for a Simple Passive Walker Using Computed Torque Method (RESEARCH NOTE)
Abstract The simple passive dynamic walker can walk down a shallow downhill slope with no external control or energy input. Nevertheless, the period-one gait stability is only possible over a very narrow range of slopes. Since the passive gaits are extremely sensitive to slope angles, it is important to use a control strategy in order to achieve a wide range of stable walking. The computed to...

متن کاملOrbital tests of relativistic gravity using artificial satellites.
We reexamine non-Einsteinian effects observable in the orbital motion of low-orbit artificial Earth satellites. The motivations for doing so are twofold: (i) recent theoretical studies suggest that the correct theory of gravity might contain a scalar contribution which has been reduced to a small value by the effect of the cosmological expansion; (ii) presently developed space technologies shou...
متن کاملTheona Theory of Relative Satellite Motion Flying in the Formation
Satellite formation flights are considered in the past few years as an effective alternative to large expensive satellites. The dynamics of relative satellite motion flying in the formation is complex and requires detailed study. This paper presents the approach based on the THEONA semi-analytical satellite theory and developed for orbits with arbitrary values of the eccentricity. The intermedi...
