LAGEOS-2 is the joint NASA–ASI laser-geodynamics mission launched on STS-52 in October 1992. Its passive reflector sphere complements LAGEOS-1 from a different orbital inclination. Ground-based ranging supports tectonic-motion and Earth-rotation measurements, reference-frame realization and tests of relativistic orbital effects.
