Mariner 6

NSSDCA ID: 1969-014A

Telecommunications Description

Data were transmitted via the high and low gain antennas to the Deep Space Network stations at Goldstone, Woomera, and Madrid. Only the Goldstone 64 meter antenna was capable of receiving the 16,200 bps transmissions.

Data was returned by Mariners 6 and 7 directly and via the analog and digital tape recorders. During the early approach phase TV images were stored on the analog tape recorder, played back to Goldstone at the high bit rate, and the onboard tape erased. At the start of the near-encounter sequence both analog and digital tape recorders were operated. The analog recorder captured all TV images, the digital recorder all other science data plus every seventh picture element. Digital data were also transmitted directly by the high rate telemetry. After exit from occultation, the digital recorder was played back and transmitted to the Goldstone, Woomera, and Madrid tracking stations at 270 bps. The next day the analog data were played back twice to Goldstone at 16,200 bps over 6 hours, after which digital playback at 270 bps was resumed. At the next Goldstone opportunity, the analog tape was played back once again. The analog recorder was played back 3 more times at the high bit rate, and then transferred to the digital recorder for playback at 270 bps.
