THE UNIFIED LUNAR CONTROL NETWORK - 1994 VERSION

The objective of the unified lunar control network is to combine a ser ies of control networks into one compatible network with its origin at the center of mass of the Moon and its coordinates referred to the me an Earth/polar axis system. The initial unified system contained 130 n earside points from Apollo data and 1026 from telescopic data. If also contained ten Mariner 10 points. The total number of points was 1166. The current network includes modifications to the past network and ex tends the coverage. Coordinates of points north of the Apollo region h ave been recomputed based on Galileo images from the second Earth-Moon flyby. Coordinates of points in the Apollo region were held fixed; ho wever, coordinates of points north of the Apollo region in the telesco pic region and many Mariner 10 points were recomputed. All of the Mari ner 10 points were remeasured and integrated into the network. Additio nal points in the Apollo region including the farside have been added. The unified network now contains 1478 points. Apollo, Mariner 10, and Galileo pictures all contained some farside points. The coordinates o f the 1478 points are available only in the microfiche supplement to t his paper.
