He has yet to wonder how satellites could transmit very long. After all,
there would come a point in time where the charge would be so high on the
vacuum insulated satellite

"The use of the term ground (or earth) is so common in electrical and
electronics applications that circuits in portable electronic devices such
as cell phones and media players as well as circuits in vehicles such as
ships, aircraft, and spacecraft may be spoken of as having a "ground"
connection without any actual connection to the Earth. This is usually a
large conductor attached to one side of the power supply (such as the
"ground plane" on a printed circuit board) which serves as the common return
path for current from many different components in the circuit."

that it could perform his field emission any longer.

In the vacuum is the rare plasma. The are free charges.

It should be easy to observe as the signal strength would decrease with
time. I haven't noticed that effect myself, nor has anyone else.

Are you sure?
Each ground must be large enough. Engineers know what to do.
Sometimes they water the ground area.

In the space the chassis must be large enough.
