## Why It Matters
Tianlian I-01 is part of China’s Tianlian I series of data tracking and relay communications satellites, a class established to provide tracking and relay support for Chinese space activities. As a relay node, a Tianlian I satellite helps transmit telemetry, tracking, and command data between spacecraft and ground stations, reducing gaps in direct ground contact. Being manufactured by the China Academy of Space Technology and operated by the China Aerospace Science and Technology Corporation, Tianlian I-01 represents integrated national capability in satellite manufacturing, launch, and mission operation. Its successful launch on 2008-04-25 aboard a Long March 3C from Xichang augmented China’s on-orbit communications infrastructure and contributed to the operational deployment of the Tianlian I series. For researchers, engineers, and policymakers, Tianlian I-01 is a documented example of Chinese relay-satellite deployment and a reference point in the development timeline of China’s space-based tracking and communications resources.
