Analysis of lunar ranging data of 1970–2001 was carried out to
estimate values of the lunar phase angle 
and Love's
number 
. The Moon's dynamic theory has been constructed
by simultaneous numerical integration of equations of motion of the major and
minor planets and the Moon with equations of lunar librations.
Partial derivatives with respect to estimated parameters were obtained
following the method of arbitrary constant varying.
