Constellations of satellites are being proposed in large numbers; most of them are expected to be in orbit within the next decade. They will provide communication to unserved and underserved communities, enable global monitoring of Earth and enhance space observation. The idea of a constellation of satellites appeared in the …

Satellite communications involves four steps: An uplink Earth station or other ground equipment transmits the desired signal to the satellite; The satellite amplifies the incoming signal and changes the frequency; The satellite transmits the signal back to Earth, and The ground equipment receives the signal. Satellite communications networks consist of user …

A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. The benefit of a satellite communications network lies in its ability to link users to voice, …

Deep-space and long-duration missions, where both crew members and spacecraft no longer benefit from the protection of Earth’s magnetic fields, are considered high risk for adverse radiation impacts. Aircraft flying at altitude, at about 30,000 feet and above, also are starting to experience radiation-induced effects. “There are 500 times more …

The solar cells produce electrical power (current) from incident sunlight. However, individual solar cells generate very little power. So, in order to generate more power, a group of cells that are present in an array form can be used. Solar arrays are primarily used in satellites in order to provide …
