Folks,
Back when I was on the EE faculty at the University of New Orleans,
one of the Civil Engineering guys was hosting an instrument from the
Geodetic Survey people. It was an automated system that would repeatedly
drop a weight in a vacuum and measure its fall to determine g locally.
Apparently they have this mapped out for the country. And I have also read
that the Air Force has g mapped out for the Earth. They need this for
proper trajectory calculations of ICBMs.
