This direction finder is part of the GPS infrastructure that supports the distribution of
images. Leading-edge technology is mated with simple physical profiles to produce a vital
piece of the PBase empire. It appears to be rather simple and unsophisticated, but without
it, your mouse clicks would produce an image that wasn't in the gallery you were surfing.
The PBase help center would then be overloaded with calls about faulty links, and no one
would be happy. This is another example of careful planning.
