Good geodetic quality GPS antennas have well defined phase centers that
are stable at the mm level. This is even though the antenna element
might be the size of a small plate and the groundplane (chokering) is
the size of a pizza.

Above said, I would explore a digital camera solution for the OPs
problem.
