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 [...]

Earth stations are mainly designed in order to connect to the satellites, receive payload information and send control commands. Along with the advancements of space department technologies, and through developing satellite earth systems which are applicable by spending acceptable money and energy, educational and research programs of space fields at universities and research centers can be developed and boosted. So by having experiences gained through connection with active satellites of space and also by training efficient personnel, when launching satellites, risk and expenses would decrease to a great extent and it would also result in space projects efficiency.Thus space research [...]

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 is reaction wheels in which the reaction force made because of rotation's start, rotation's speed change, or rotation's stop can be used as propulsion of attitude's change. Due to the country's need and in order to achieve to the designing and manufacturing technology of [...]

Virtual simulator is a device which helps to analyzeand assess space systems functions and their control algorithms without any difficulty or hardware problems. Considering this issue and also country�s need to have access to such products, virtual simulator of space systems is designed and operated at space research Laboratory. This simulator, by the use of basic attitude models and also satellite transmission models has the capability to simulate transmission link of geosynchronous satellite and also the dynamic of satellite's attitude in a virtual way. All the stages of designing and producing of this simulator is done completely in space research [...]

In space systems design process, the use of system analysis is inevitable. System engineering makes it possible for the designers to carefully consider all dimensions of the problem. In system engineering process, the relationship between workgroups, subjects and different subsystems is appropriately made possible through software. Due to the design and manufacturing of different space systems in the country, the need to perform systematic analysis is felt more than before. Thus space research Laboratory has begun to design and produce design and system analysis software in the form of different subjects. Such software are: the software for conceptual designing of [...]
