Propelling a spacecraft by using solar radiation pressure is examined in the context of orbital maneuvers. A locally optimal steering law to progressively change number of selected orbital elements together is addressed. An Earth centered cubesat satellite with solar sail is used as an example. The proper attitude maneuver mechanization is proposed to harvest highest solar radiation force in the desired direction for Earth orbiting satellites. The satellite attitude control is realized using to-go quaternio...
Attitude determination and rotational motion parameters identification of a LEO satellite through magnetometer and sun sensor data
Kutlu, A.; Haciyev, Ch.; Tekinalp, Ozan (2007-06-16)
In this paper, Attitude Determination and Parameter Identification problem of a LEO satellite are studied. In Attitude Determination System three rate gyroscopes, three axis magnetometer and a sun sensor data are used. Using Kalman Filter algorithms angular rates and quaternions are estimated. In these algorithms, rate gyroscope bias measurements are also taken into consideration in state estimation. In Parameter Identification part, the Moment of Inertia values of the satellite are estimated by using Least...

Spacecraft energy storage and attitude control
Altay, A; Tekinalp, Ozan (2005-06-11)
The energy storage and attitude control technologies in spacecrafts are considered. The conventional technologies like electrochemical batteries, reaction wheels and control moment gyroscopes are compared to the promising Integrated Power and Attitude Control System with Variable Speed Control Moment Gyros (IPACS-VSCMG) technology. For this purpose, various energy storage and attitude control system conceptual designs are carried out, and the results are compared. Also given a simulation to show the effecti...
