Satellite communication can provide many benefits and complement terrestrial networks. They can provide service continuity, to provide network access over uncovered and under-covered areas. They can provide backup or service ubiquity, to ameliorate the network availability in cases of temporary outage or destruction of a ground network due to disasters. …

Propulsion systems can be classified based on their dependence on the onboard power: electric and non-electric systems. Electric propulsion systems are mainly classified into resistojet, electrospray, ion, Hall and pulsed plasma systems, and they actively require on-board power for their operation, while the non-electric propulsion systems can be classified into …

Satellite communications represent a cost effective and reliable means of transporting voice, video and data to and from remote locations. The satellite industry is one of those industries where network management plays a key role. Therefore, the requirements for network management solutions for the satellite market are usually very stringent. For …

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. In a Low Earth Orbit (LEO), a satellite completes about …

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 …

Substantially more spectrum bandwidth is available at the Ka band than at the Ku band and other lower frequencies. For example, Ku band allocation is around 2GHz for uplink and 1.3GHz for downlink with actual contiguous bandwidth allocation of less than 0.5GHz per satellite. In comparison, the Ka band SATCOM …
