The Role of Extremely Accurate Surveying Techniques in Existing Geodetic Networks the U.S.A., the highly accurate data have their greatest effect in setting the scale of the network, and that probably only a small amount of data is needed. Increasing the number of points affected can help identify weak spots in the networks, but such identification can also be done by analyzing the less accurate data.

Analytical Theory for the Rotation of the MoonMoon’s principal axes of inertia, relative to an ecliptic coordinate system, are then obtained as Poisson series, the sine or cosine coefficients being explicit functions of the harmonics coefficients.

Maurice Ewing and the Exploration of the Oceansly as a synthesis of relatively new information from marine geology and geophysics, a field where Ewing did much of his best-known work. Therefore, before a group representing diverse physical disciplines, it is appropriate that we should briefly review this important development and Ewing’s substantial role in it.

Free Librations of the Moon from Lunar Laser Rangingnation of them is obtained for the three modes of these oscillations of which the amplitudes are found to be: . (longitude), . and . (latitude) for the terms with the respective periods 2.9 years, 27.3 days and 75 years.

Conference proceedings 1977igent now than they were five centuries ago, or indeed five millenia ago. The differences are in the pool of past experience and the availability of means for manipulating the physical and mental environment. Until fairly recently, the development of new technologies in astronomy and geodesy has ser

Mathematical Modelling of Lunar Laser Measures and their Application to Improvement of Physical Para into the computational procedures required to treat the data that may not be obvious to the non-specialist. This paper is a conceptual description of the step-by-step process required for the computation of lunar range predictions, showing both the nature of all of the mathematical aspects of the p

Present Scientific Achievements from Lunar Laser Rangingoon. The typical accuracy, expressed as a one-way distance, is 13 cm and the best accuracy is 8 cm. Several groups have successfully analyzed this data and their results are reviewed here. Typical of these fits is an analysis of over 1700 ranges resulting in an rms residual of 44 cm, the difference
