Satellite Communications Connect People and Business across Sea, Land and Air
A communications satellite can be defined as an artificial satellite that relays as well as amplifies radio telecom signals via a transponder. It can create a communication channel between a source transmitter as well as a receiver at multiple locations on Earth. This type of satellite can be used for TV, telephone, internet, radio, and military applications. Based on 1st August 2020, there are 2,787 artificial satellites in the orbit of the Earth, with 1,364 of these being communications satellites, that both private and government organizations can use.
Many communications satellites are in geostationary orbit 22,236 miles above the equator. The satellite appears stationary at the same point in the sky. Hence, the satellite dish antenna of earth stations can be focused on that spot and do not have to shift to track the satellite.
The radio waves of high frequency can be used for telecom links travel by line of sight and are obstructed by the Earth’s curve. The objective of communications satellites is to relay the signal around the curve of the Earth that allows communication between separated geographical points. These satellites can be used for a wide range of radio as well as Microwave frequencies. In order to avoid signal interference, international organizations come with regulations for which frequency ranges or bands, specific organizations are allowed to use. The allocation can reduce the risk of signal interference.
Communication satellites are composed of the following subsystems, including
• Engines can be used to bring the satellite to its desired orbit
• Communication payload, composed of transponders, antennas, and switching systems
• A communication station can keep tracking as well as stabilizing subsystem to keep the satellite in the right orbit, with its antennas pointed in the right direction.
• Power subsystem can be used to power the satellite system, composed of solar cells as well as batteries that maintain power during a solar eclipse.
