How much did the Company know about the alien signal and when did they know it?
We may never know on film, but I have always enjoyed the explanation in this excerpt from Alien, the movie novelization, and its suggestions about the larger universe in which Nostromo operates.
(Give not special significance to the yellow-highlighted word “Mother”; I am researching the novel for references to the computer and I forgot to removed that.)
