Simultaneous optical observations from the beta mu-11962 satellite have been used to calculate the threedimensional orientation and geodetic azimuths of lines ranging from 400 km to 1600 km in length. These directions were subsequently used as input to a conventional first-order triangulation adjustment and a three-dimensional surface adjustment to establish the geodetic positions of the camera sites. It is concluded from this study that the station-to-station directions can be computed within an accuracy of 0.7 sec for the three-dimensional fix and to within 0.5 sec for the geodetic azimuth. The conventional and three-dimensional adjustments produce an average root-mean-square error of 6 m in position. (Author).
The azimuth reduction technique from satellite data presented in this report is developed with the aid of matrix algebra. It is fully general in that provisions are made for correlated observations. The reductions represent a rigorous least squares approach to the reduction of optical data gathered from satellite observations. The matrix equations are outlined in such a fashion that they can easily be used in the development of computer programs to perform azimuth reductions from simultaneous observations of satellites from two widely separated ground stations.
