| Research Abstract |
Geometrical and dynamical scales of the Earth are determined from satellite laser ranging. The gravitational constant GM, the scale of a terrestrial reference frame and a range bias are highly correlated, which has degraded the determination of the scale parameters. As a result of a numerical simulation, the combination of multiple satellites at various attitudes is found to be the key to solve the problem.
