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 …

Digital Signal Processors (DSP) take real-world signals like voice, audio, video, temperature, pressure, or position that have been digitized and then mathematically manipulate them. Signals need to be processed so that the information that they contain can be displayed, analyzed, or converted to another type of signal that may be …

A satellite broadcast network consists of a transmitting hub station and a number of receive-only earth stations, and uses the resource of one or several channels (transponders) of a communications satellite. It relies on a star topology and point-to-multipoint connectivity. Links are unidirectional, from the hub towards the earth stations. …

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 …

A system is defined by NASA as a construct or collection of different elements that together produce results not obtainable by the elements alone. Systems Engineering (SE) is defined as: The process by which a customer’s needs are satisfied through the conceptualization, design, modeling, testing, implementation, and operation of a …

In the middle of the 1990s, the common way of developing software was a heavyweight software development methodology, comprising of complete requirements documentation of design and architecture, followed by coding, integration, and finally testing based on a detailed test plan before an application was deemed production-ready. This traditional and sequential life …

All systems are designed to achieve some human purpose: The web application Facebook connects people in a social network, an aircraft transports people long distances. A Boeing spokesman once quipped, “We view a 777 airliner as a collection of parts flying in close proximity.” The job of a systems …
