A frequency generator is used to measure the signal delay between two surveying space objects. Thermostatting allows an increased level of stability. The temperature control system is the main thermal mode support system onboard. The mathematical model of this system is considered in this article. The analysis of factors influencing on Earth Satellite Vehicle is carried out. The variant of protection against kinetic influences is offered.

The paper deals with the replacement problem of the containment prestressing system (CPTS) at the extending stage of CCB life characteristics. The features of domestic CPTS used in the blocks construction in the 80s and the system developed by the French company Francine - CPTS-M used today as a replacement for the units modernization are studied. The paper describes their features and some problems associated with the monitoring organization of the unit life extension period.

There are a variety of methods concerning the examination of dangerous structures and rehabilitation of their robustness. One of the methods is uplifting and alignment of buildings with the use of hydraulic jack. Development of the uplift and alignment program is possible if there is a data, which is to be received both before the beginning of the uplift and during the process of recovery of spatial geometry of the building. The development of the uplift and alignment program automatically controls the speed rate of the hydraulic system. The suggested method enables an accurate control of a vertical reach and provides the minimal overload on deformable footing and structure of the building during its uplift and alignment.
