In this article the authors consider the problem of structuring knowledge about the control process and control object and their application in monitoring manned space vehicles. The authors identified and justified the need to unite the accumulated experience of controlling flights of manned spaceships as a single subject area. Basing on the study, the authors propose a new approach to structuring knowledge about the control process and control objects ; they also consider methods of solving the task and practical application.

Decision-making process during real-time flight control operation possible facilitate to having formalized description means of the script of flight control operation. Especially it is become important at deficiency of time which is characteristic for the decision-making process. The script, in this case, is the description of flight control process of the space vehicle directed on achievement to one the goals of flight control. The given description is possible in discrete space, for example time, with degree of accuracy. The description represents possible set phase of trajectories which can use the flight control system. In this case, the script will represent complex enough formal design in which various elements - models, scales, variable - achievements of the considered purpose describing process.

During real time flight operations оne of approaches to increase efficiency of the control of space vehicle’s parameters is creation of hierarchical monitoring system. Such system has to monitoring data from space vehicle in a ground contour of flight control. At creation of the hierarchical monitoring system there is a problem of an estimation information loading levels on its structural elements. Also distribution of information loading between structural elements of the monitoring system should be uniform, providing thus conditions of effective and reliable work of the system. In article described one of possible approaches to formalization of distribution of information loading is considered by modeling the hierarchical monitoring system.

Any on-board system is a complex technical system, and its analysis requires special mathematical methods. The number of parameters describing the state of the spacecraft, there are tens of thousands. Each such parameter characterizes the state of node, block, unit, subsystem of any on-board system, or any aspect of the operation of this site, the block unit. To estimate the state of the spacecraft and support decision –making requires an estimate of the set of parameters describing the state of this spacecraft. One of the approaches that allow facilitates the process of search for a solution to a group of flight control of spacecraft is presented in this article. This method is the use of "trees" search condition. This approach allows us to optimize the process of analysis of the systems on board. Also, the use of "trees" search state allows you to automate the analysis process and implement its program, organizational, hardware.

State of the spacecraft is characterized by a certain set of parameters obtained from the spacecraft through telemetry. For operational decisions based on of analysis of the parameters that need the function of estimation, which shows the variation of these parameters. The article describes how to construct the function of estimation for a continuous parameter and another one parameter with a bilateral constraint the feasible region. You can see also example of the function of estimation with using expert assessment and use of color coding for the automated estimates and for decision support. The functions of estimation are often used by operational management team for the prediction and identification off-optimum situation on spacecraft and also operational decision making to overcome the off-optimum situation.
