Power & Antenna Subsystems
The antenna subsystem is complicated mechanical assemblies that are folded into dense packet for launch and must be deployed in large accurately alight assembly during orbit.control sub system provide tracking signal for precise pointing of antenna towards the earth coverage area. Satellite communication system uses a variety of antenna system. This maybe linear dipole helix horn antenna array and parabolic reflector However, the parabolic reflector is most commonly used antenna as it gives a highly directional symmetric radiation pattern
