Default GPS problems in a dome

Agreed. However in a fixed location the purpose of the GPS is to
automatically input the correct date and time.
You can do this manually but it is easier to let george do it.


However, in most cases a setup like this will be controlled by a
computer. Telescope control software is perfectly capable of
synchronizing the time with the mount. After the first sync, the mount
doesn't need its time to be super accurate, anyway.

Most people I know with a fixed LX200 GPS disable the GPS simply because
they get tired of waiting for the scope to get its bearings. With the
GPS off, you turn on the scope, unpark, and are ready to go.

(Actually, I'm surprised the GPS doesn't work through the dome. I have a
GPS time receiver on my observatory computer, and it works just fine
through a steel rolloff roof. I'd think a fiberglass dome would be no
problem at all.)
