TECHNICAL DEFINITION

Bandwidth, in the context of satellite communications, quantifies the data transmission capacity of a communication channel, representing the range of frequencies available for signal transmission and directly impacting the volume of data that can be sent or received per unit of time.

BACKGROUND

The International Space Station (ISS) is a space station in low Earth orbit (LEO). It is the product of the International Space Station program and is operated by five partner space agencies: NASA, Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). It is the first space station built, maintained and crewed through international cooperation and the largest human spacecraft ever constructed. It is an orbital research station, where scientific experiments in microgravity are conducted and the space environment is studied. Since 2 November 2000, it has hosted the longest continuous human presence in space. Alongside China's Tiangong, it is one of two operational space stations.
