Comment on Could I just create my own drive format?

  I wonder if anyone has ever passed messages between spacecraft as a peculiar form of delay line memory – or pinged a satellite at a predictable distance as part of a timing system…

    No but I look forward to this in the next Andy Weir novel

    Isn’t that just GPS in reverse? I mean, same equation, different dependent variable 😁

    I vaguely recall what was effectively a delay-line implemented using terrahertz-modulated lasers aimed at the retro reflector on the moon from Earth’s surface. The data storage capacity was something in either the hundreds of GBs or low TBs. But I can’t find the reference.

      I think I’ve read about a similar project where someone would send packages across the internet, and use the delay as a form of memory. The capacity wasn’t great, but the idea was really cool regardless.

  So a network version of an acoustic delay line?
