Popis:	A simulation is described for measuring the newtonian gravitational constant G in the SEE space experiment. Two methods are examined for estimating G: the two-point method and the integral one. When the two-point method is used, to provide an error not more than ΔG/G ≈ 1·10−6 requires path measurements to be performed with an error of not more than 1·10−8 m=λ/50 (λ is the green line wavelength). In the integral method, the same error in estimating G is attained with an error of measurement different by two orders of magnitude, 1·10−6 m.
