The Space Network (SN) was established in the early 1980s to replace NASA’s worldwide network of ground tracking stations.

The Space Network consists of:

  • A constellation of geosynchronous (Earth orbiting) satellites named the Tracking Data Relay Satellite (TDRS),
  • Ground systems that operate as a relay system between satellites
  • Satellites in low Earth orbit (LEO) above 73 km
  • Ground facilities

Network Availability

The Space Network is operated 24 hours a day, seven days a week, 365 days per year. Operations on the network run above 99.5% proficiency every month. Usually the Space Network operates above 99.9%.
