- PIONEER 6 STATUS REPORT
- November 11, 1992
-
- Yesterday, the Deep Space Network's 70 meter antenna in Goldstone,
- California supported a tracking pass of the Pioneer 6 spacecraft. Receiver
- lock was attained, but we were unable to attain telemetry lock because no
- subcarrier was detected. The expected bit rate was 16 bps uncoded telemetry.
- The AGC (Automatic Gain Control) was initially at -175.3 dbm, but was seen to
- fluctuate causing the receiver to toggle in and out-of-lock. The problem is
- under investigation.
-
- Pioneer 6 was launched on December 16, 1965 and is the oldest surviving
- spacecraft. Pioneer 6 was last supported on December 16, 1990, on the
- 25th anniversary of its launch, and no problems were encountered then.
