From the viewpoint of improved precision, resolution, area coverage, and other terrain mapping considerations, a large format camera of 30-cm focal length and a pair of stellar cameras to determine camera attitude were recommended for Apollo Missions. In this paper, the potentials of a Large Format Camera (LFC) photography are explored specifically for the purpose of carrying out photogrammetic control extension. This study is based on the error propagation analysis is in photogrammetric triangulation of a block of 22 LFC frames, having and approximate scale of 1:755,000 and taken during the October '84 Shuttle Mission 41-G. The results of the study are shown graphically as error curves of each of the simulated systems. The best results are achievable when the Geodetic Positioning System (GPS), along with minimum ground control, is used in the LFC photography block triangulation. The stellar camera is also useful in conjunction with the Geodetic Positioning System, in areas where the ground control is not available for use in the block triangulation. Average standard deviation of determination of coordinates of triangulated ground points can be as good as + or - 2.7 meters + or - 3.5 micrometers (planimetry) and + or - 5.4 meters (elevation). These correspond to + or - 3.5 micrometers (planimetry) and ; or - 7.2 micrometers (elevation) at the photo scale.
