Space is becoming more dynamic than ever with mega-constellations, multi-orbit satellites, and software-defined payloads. The world’s demand for broadband connectivity has created a new generation of high-throughput satellites in geosynchronous Earth orbit (GEO), medium Earth orbit (MEO), and now low Earth orbit (LEO).   In the future, 5G networks will …

The small satellite is one of the fast growing sectors in space industries. Small satellites usually refer to satellites below 500 kg, including minisatellite (100–500 kg), microsatellite (10–100 kg), nanosatellite (1–10 kg), picosatellite (0.1–1 kg), and femtosatellite (<0.1 kg).   Cube Satellites, aka CubeSats, are a class of nano satellites …

The constant growth of interest in high-speed wireless communications causes the search for new solutions and new types of radio access networks. Although more than half of the global population is already connected to the Internet, there is still a need for higher broadband connectivity and telecommunication services in suburban, …

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 …
