Telemetry

TECHNICAL DEFINITION

Telemetry is the wireless or wired transmission of data, including sensor readings, performance metrics, and status information, from remote or inaccessible sources (e.g., spacecraft, rockets, drones) to a receiving station for real-time monitoring, analysis, and control.

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 presence of humans in space. Alongside Tiangong, it is one of the only two currently operational space stations.

SYNONYMS & ALIASES

• Remote data
