Abstract
A gravimeter that utilizes an electromagnetic launcher for enabling a free-fall of a test mass is disclosed. The electromagnetic launcher propels the test mass upward such that the test mass begins to free-fall once it has reached the apex of its flight. In addition, in some embodiments, the test mass comprises only non-ferromagnetic materials so that the free-fall of the test mass is unperturbed by magnetically induced influences.
