The collection contains methods, algorithms and results of building a selenocentric coordinate system for the lunar survey area from the spacecraft "Zond-8". A fundamental difference between the methods created and those used earlier for this kind of work , is the use of the fundamental idea of joint determination of the coordinates of the points of the catalog and the parameters of the orbit of the spacecraft according to the processing of the coordinates of the images of the points of the physical surface of the Moon and the Earth measured in the images , altimeter data, telemetry information about the moments of shooting , CA Traffic Forecast Data. Measurement processing algorithms are based on the theory of the generalized method of least squares and the theory of estimations of the state and parameters of dynamical systems. In this case, the coordinates of the design centers at the time of shooting are also used as dynamic constraints. requiring ownership of orbital design centers when solving network construction tasks, and as stand-alone navigation data to solve the edge orbital refinement problem, selection of the optimal model of the gravitational field and determination of the selenocentric gravitational constant. The main results of the work are: created methods and algorithms ; coordinate catalog of the 881st point (attached to the edges), implementing the "Zond-8" system ; the value of the selenocentric gravitational constant, which was determined in the process of constructing the catalog together with the orbital parameters of the spacecraft; calculated orientation and position parameters of the "Zond-8" system relative to the "Apollo" system ; software complex containing about 300 modules, with documentation for its maintenance and operation on a computer .
