More Data from Voyager 1

For the frames which can't be decoded with confidence due to the SNR being too low, I assume that if a couple of bits of the frame data were known, that would enable the rest of the frame to be decoded.

Since the data appears very similar between frames, it seems easy to select some bits which are highly likely to be constant, enabling the whole of the rest of the frame to be decoded...

Certainly the format is documented at NASA. Could someone obtain a copy with a FOIA request?

i remember an article, maybe on arstechnica maybe a decade ago about a group of enthusiasts who had found some old satellite computer at a home. they looked it up and found it belonged to some old satellite nasa had forgotten about so they asked for permission to try to contact it and eventually they did get it to run a booster after decades. Don't know what it was but this sounds like that somewhat

>> At the beginning the output is around zero because the loops haven’t locked yet.

They could run the PLL on the signal backwards. This would provide lock at the beginning. Combining that phase measurement with the forward one might also reduce phase error in general.

Cool! It even show the bits! Now, what do they mean? What are the fields? What science/instrument data was gathered?
