This portal must be opened in space and then dropped onto the surface of Earth, in geosynchronous orbit, the opening will be more or less fixed at a particular location.
Unless, there is a way to project the opening upwards into space aimed at GSO station; maybe one of these,
without building big pyramids. Which reminds the question, why one end of the portal is always in water? That water will seal the opening naturally and immediately upon exit or entrance?
