English Abstract

In this study, the rotations around all three axes are performed practically by designing a small prototype for the (3-Axis Stabilized Satellite).

The prototype shown in this research placed in space by using suitable mechanism.

The panels is neglected for the design to be lighter in weight and offer more space for the designed prototype to rotate around the three axes (Pitch, Yaw and Roll).

Instead of solar power, Dc power supply is used.

The actuators are DC geared motor with a jack that slides in and out.

The length of the jack rod is modified to adequate the design and for the roll axis the rod is removed.

The computer and a (DASYLab Application Software) are used with (DAQpersonal3001) hardware to drive the motors.

The motors that have high current rating interfaced with the (DAQpersonal3001) hardware using interface circuits that comprises Transistors and relays as main components.

The interface circuit separates the low command signal generated from the (DAQpersonal3001) to the base of the transistors and the power that operates the actuators of the design.

The linear type potentiometer used as an angle sensors to measure the degree of rotation around the three axes.

Several maneuvers performed to test the system and several relations drawn between the angle in degrees and the time spent for each rotation.

The results in average show that the relation between the angle and time spent for each rotation in this study is linear relation.
