Earth stations on moving platforms (ESOMPs)

Satellite communication systems consist of two main segments, the space segment and the earth or ground station. The ground station system coordinates the communication process with satellites in space. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication …

Aircrafts and Rockets for global military logistics, space travel, asteroids and moon mining

Multiple countries are developing the ability to mine in space, specifically on the moon and on asteroids. The moon stands out as a nearby example of what will soon be the site of regular operations. The moon is home to hundreds of billions of dollars-worth of natural resources, including helium-3, …

Satellite On-board connectivity through beam switching and scanning

High-throughput Satellite or HTS systems represent a new generation of satellite communications systems, that provide a significant increase in capacity than conventional communication satellites. They utilize frequency reuse and multiple spot beams to deliver vast throughput for the same amount of allocated orbital spectrum. The increase in capacity typically ranges from 2 …

New Space Satellite Communication Networks and terminals Test & Measurement challenges and solutions

Traditionally, the satellite industry has relied on geosynchronous earth orbit (GEO) satellites that take years to build and require very expensive launches to deliver them to orbit. Satellite networks using geosynchronous equatorial orbit (GEO) are effective at providing stationary coverage to a specific area, however, Latency issues due to the …

Nanosatellite and Microsatellite Market growth and trends

Nanosatellite and microsatellite refer to miniaturized satellites in terms of size and weight, in the range of 1-10 Kg and 10-100 kg, respectively. ‘CubeSat’ is one of the most popular types of miniaturized satellites. These are the fastest growing segments in the satellite industry. One of the major advantages of nano …
