Geodetic uses of lunar laser ranging

A recent improvement in measuring accuracy together with the development of new techniques suggests that geodetic point coordination to 1 part in 10⁸ will become a reality in the near future. As a first step, however, the reference frame in which the points are to be coordinated, must be refined. Lunar Laser Ranging offers a means of solving both of these problems. The necessary equations are developed and the shortcomings of the method are analysed.
