What exactly does multihopping mean?

[Grand Ship Builder]

What does multihopping mean, exactly? I've seen it on some command pods, and even searched it up on what it means, but nothing really explained to me what it is. So I decided to go here, the forums, to ask this very question.

 

 

So what does multihopping mean?

Singlehop means: if you have the right hardware setup, a pilot onboard "ship1" can control a rover on a distant planet, if the pilot has LOS to the rover -- even if both have no connectivity to Kerbin.

Multihop means: the pilot can still control the rover even if there is no LOS, as long as there is a sequence of relay connections between ship1 and the rover.
