TTS, TETR (ERS)

 

TTS [NASA]

TTS, TETR, TATS (Test And Training Satellite) were four very small magnetically stabilized satellite instrumented with a s-band transponder to provide training to Apollo ground stations. Its external configuration was an octahedron, 12 in. on each side. It was powered by solar cells mounted on the octahedron surfaces and nickel cadmium batteries. The instrumentation included the 9.5 watt s-band transponder, a PAM/FM/PM telemeter encoder and 100 milliwatt VHF transmitter. The spacecraft was built by Thompson Ramo Wooldridge, Inc. (TRW).
