Abstract

For today, practically any onboard complex belongs to the class of difficult technical systems. Therefore, improvement of quality of functioning and definition of full technical condition of onboard systems is an important problem. In providing the demanded level of quality of functioning and reliability of difficult technical systems the special role belongs to various methods of diagnosing, after all mission of all device depends on work of these systems, and working capacity loss at least of part of onboard system is inadmissible today.

Therefore, the main task of any designer of onboard systems is an assessment of quality of reliability of the onboard equipment. However, ideal «working capacity» and full «not working capacity» in practice meet very seldom, these states are now certain boundary a state on a scale of all possible conditions of the spacecraft rather.

At this stage of development of onboard systems, complete control of a state is exercised through the analysis of telemetric information. We will consider as it occurs. Some information shots about a condition of a certain onboard system prepare, then they are prepared in a format for transfer on a land complex of reception of telemetry, then there is a communication session after that the telemetry is analyzed and if in information there are any shots which it is required interventions of land operators, information transfer about reconfiguration of «critical» system is made. It is not difficult to track a long chain of interactions.

Here it should be noted that all emergencies share on parried, i.e. expected and not expected. In addition, if information in telemetry indicates not expected emergency, time for decision-making on parrying of such situation can extend very strongly in time, this time can be fatal, especially if the device calculated on development of distant space.

For the reason that possibility of the automated identification «before — defective» states onboard KA isn’t provided, all this doesn’t give the chance of a prediction of a condition of KA on the following communication sessions and doesn’t allow to take in due time a measure on prevention of hardware failures.
