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).
