t. e. A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military ...
A high altitude platform can provide observation or communication services. A high-altitude platform station (HAPS, which can also mean high-altitude pseudo-satellite or high-altitude platform systems), also known as atmospheric satellite, is a long endurance, high altitude aircraft able to offer observation or communication services similarly to artificial satellites.
A telecommunications satellite. The space segment comprises the uplink, the satellite itself, and the downlink. The space segment of an artificial satellite system is one of its three operational components (the others being the user and ground segments).

High-throughput satellite (HTS) is a communications satellite that provides more throughput than a classic FSS satellite (at least twice, though usually by a factor of 20 or more [1]) for the same amount of allocated orbital spectrum, thus significantly reducing cost-per-bit. [2] ViaSat-1 and EchoStar XVII (also known as Jupiter-1 [3]) do ...
The Wideband Global SATCOM system (WGS) is a high capacity United States Space Force satellite communications system planned for use in partnership by the United States Department of Defense (DoD), Canadian Department of National Defence (DND) and the Australian Department of Defence. [1] The system is composed of the Space Segment satellites ...
Tiantong-1 satellite mobile communication system is China's self-developed and built satellite mobile communication system, but also an important part of China's space information infrastructure. The system consists of space segment, ground segment and user terminal. The space segment plans to consist of several geosynchronous orbit mobile ...
Illustration of the DSCS III satellite. The Defense Satellite Communications System (DSCS) [ 1 ] is a United States Space Force satellite constellation that provides the United States with military communications to support globally distributed military users. Beginning in 2007, DSCS began being replaced by the Wideband Global SATCOM system.
