A test loop translator ( TLT) is a type of radio frequency converter or heterodyne, used to translate between uplink and downlink segments (generally in the same band), to allow for "loop-back" testing and calibration of a satellite ground station without the need to interface with the satellite. [1] [2] The test loop translator is an extremely ...

A communications satellite 's transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. [1] It is mainly used in satellite communication to transfer the received signals. A transponder is typically composed of: an input band-limiting device (an input band-pass filter ),
Ground station. A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft (constituting part of the ground segment of the spacecraft system), or reception of radio waves from astronomical radio sources. Ground stations may be located either on the surface of ...
A broadcast translator is a low-powered (maximum of 250 watts) FM radio station that retransmits the programming of a parent station that operates on a different frequency. Translators are not allowed to originate programming, and were originally designed to extend the coverage area of a primary analog FM station.
A spacecraft command language (or satellite control language, spacecraft control language, Systems Test and Operation Language (STOL), Satellite Test and Operation Language, etc.) is a computer command language for commanding spacecraft mission systems. Ultimately such languages are used to command remote spacecraft with telecommands, but they ...
How satellite internet works. Satellite Internet generally relies on three primary components: a satellite – historically in geostationary orbit (or GEO) but now increasingly in Low Earth orbit (LEO) or Medium Earth orbit MEO) [20] – a number of ground stations known as gateways that relay Internet data to and from the satellite via radio waves (), and further ground stations to serve each ...
