Wire ground vs Spacecraft Ground

SPIS
1

I am defining a circuit based on a spacecraft design with instruments on a wire boom. The wires need to be biased along with the instruments, and I was unsure if SPIS interprets wire electric nodes as the SC surface nodes (e.g. is wire node ground the same as SC surface node ground)? If not, how can I bias these separately and connect them to my instrument circuit?

The wire booms I am speaking of are defined as thin wires, I have not found any info regarding wire electric nodes in the documentation, if anyone knows where to find that would be of great help.

I am using SPIS 6.2.6.

Hi Joseph. I think the wire nodes are only treated to have a ground potential node in the output monitoring. It makes no sense to me to bias the ground from the surface on a thin element although it can have a non-conductive coating, I suppose.
You can bias the wire however you want with the normal circuit format.
