In the article, based on the concept of increasing the reliability of the formed image of the complex of technical means for ensuring the operation of an unsolicited measuring station of the network of stations of the ground control complex, a solution is proposed for choosing the general scheme of an uninterruptible power supply as part of a complex of technical means of unsolicited measuring systems. The uninterrupted power supply system is designed to automatically provide a set of technical means for ensuring the operation of a non-demand measuring station with a guaranteed and uninterrupted power supply in accordance with the indicators of reliability, autonomy and quality of electricity specified in the terms of reference. A procedure for selecting the constituent elements of an uninterruptible power supply is proposed, the main stages and composition of the protection means for the power supply network are considered. A block diagram of protection over the power supply network is presented. It is noted that structurally, the uninterruptible power supply should be able to be placed both in a stationary room and in a block container.

The article considers the problem of reducing costs for the development and maintenance of software components. The possibilities of reusing software components and as the result the need for their testing are considered. A method of the repeated testing is proposed. It allows achieving the required level of testability of software components that reduces time costs. This method is a more detailed investigation of the neighborhood of the identified failures and the elimination of already verified areas. The software implementation of the repeated testing method in the framework of the Integrated Development Environment developed by the authors is considered. The presented tool allows designers to automate the re-testing procedure partially. It is possible to predict the time of occurrence of the next error based on the data on the detected errors while testing. It is essentially the time between failures. A de-eutrophication model for predicting the mean time between failures and a software tool that implements the given model are proposed. The results obtained by testing on the known data set are presented. The models and approaches described in the article help to solve the problem that is confirmed by the results obtained using the developed software tools.
