NASA | Using Quasars to Measure the Earth: A Brief History of VLBI - 3D
VLBI, or Very Long Baseline Interferometry, is a technique that uses multiple radio telescopes to very precisely measure the Earth's orientation. It was originally invented back in the 1960s to take better pictures of quasars, but...
