Tianlian 2-01



Tianlian 2-01 is a new communications satellite to provide real-time communications between orbiting satellites and ground control stations.

The Chinese tracking and data relay satellites were developed by the China Academy of Space Technology (CAST) and it is similar to the American Tracking and Data Relay Satellite System (TDRSS) in concept. The system is designed to support near-real-time communications between orbiting spacecraft and the ground control, and will complement the ground-based space tracking and telemetry stations and ships to support future space projects.
