[image-63]

The above image represents what the TDRS configuration will be by the end of September 2014 with nine working TDRS in space. Six are operational (two first generation, three second generation, and one third generation), two are in storage (two first generation) and the newest one, TDRS-12, is under going testing before becoming fully operational sometime in the fall of 2014. After 20+ years of services, two first generation TDRS have been shut off and super-synced into an orbit about 300 miles higher than geosynchronous (GEO), where the operational fleet sits.
