The modern spacecraft’s are difficult subjects to control and diagnosing which at completions and partial modernization allow joint operation of the elements having various volume of statistical information on defects and refusals, and at times and total absence of this information. When diagnosing the onboard equipment of S the problem of reliability of decision-making is particularly acute very.

The poor quality of diagnosing can lead to adoption of wrong solutions of the technical condition and is negative influence processes of maintenance of a subject to diagnosing that leads to decrease in efficiency of the solution of tasks, or to start of S with faulty BO that means failure of the set target task. It demands further intensive development of new approaches to determination of technical condition on the basis of diverse prior and current information as the existing approaches not rather fully reflect the proceeding processes in an object and the system of diagnosing.

In this regard the technique of synthesis of the suitable program of diagnosing of the onboard equipment of the spacecraft on reliability on the basis of the hidden Markov models based on Bayesian networks of trust is developed. Application of Bayesian networks of trust in models of diagnosing allows to increase reliability of results of diagnosing at the expense of a possibility of accounting of uncertainty of results of measurements of diagnostic signs, dynamics of prior information on technical condition of a subject to diagnosing, coverage of considerable volume of diagnostic signs and also uses of parameters of the law of distribution of values of diagnostic signs and precision characteristics of measuring instruments. Use of the office of Bayesian networks of trust significantly supplements models and methods of the solution of problems of technical diagnostics.

The example of synthesis of the suitable program of diagnosing of a control system of the movement of the spacecraft on reliability is presented. According to authors, results of researches can be of interest to developers of control devices and tests of the onboard equipment of spacecraft’s both by preparation of S for start, and in flight.
