For making changes in the attitude (or position) of the satellites, considering the level of change and its kind, different actuators can be used. This actuators, by the use of Action and Reaction Principle (Newton’s second principle), can import force to the satellite without relying on any surface. One of the most important of such actuators are thrusters in which after the exit of gas from a nozzle, necessary momentum for rotation (or movement) of satellite is provided. Due to the country’s need and in order to achieve to the designing and manufacturing technology of such actuators, Space Research Laboratory has begun designing and making samples of such actuators in order to be used in micro level satellites. The property of such a model is mentioned in the following table.
Propulsion subsystem in a satellite is made up of different components whose most important parts are: cold gas tank, regulator, accumulator and thruster (including body, solenoid and nozzle)
It can be used as attitude control actuator on satellites
Different control algorithms can be tested by using it
