Article purpose – to show value and ways of implementation of the project «Global Ground – Space Information System GLONIS-KOSMOPLAN» for creation of the state system of informatization of all spheres of social development. Ways of implementation of the GLONIS-KOSMOPLAN project are created on the basis of projects of innovative space technologies, reusable aerospace KOSMOPLAN system, orbital group of medium-altitude level of system of operation of orbital constellation and system as a whole, a ground information subsystem of the mobile communication, coordinated by the general system project. The proposed structure of works is offered as option for practical design of the program of creation of operated ground and space telecommunication systems. Creation of GLONISKOSMOPLAN system will provide informatization of all spheres of social development of the Russian Federation.

STABILITY ESTIMATION OF A LINEAR NETWORK ACCORDING TO THE COMPLEX RESPONSE ENVELOPE OVER THE FINITE TIME INTERVAL

A method for stability estimation of a linear dynamic system is developed on the basis of exponential interpolation of its’ time response (in general case, complex one). As a result, the characteristic equation is obtained, which roots’ position inside or outside the unit disk is determined the localization of the system natural frequencies regarding to the imaginary axis of the p-plane. Similar conditions take place in analysis of discrete (or pulse) systems. In this case, in order to check the roots’ types, the specific criteria of Shur − Cohn and others are used or (after conformal representation of inner part of the unit disk into the left half-part of the pplane), namely tabular or determinantal criteria of Rauth − Hurvitz and Hermite − Hurvitz can be used. For example, the FET amplifier stability is estimated with slightly detuned circuits and for the feedback through the “gate − drain” capacity according the complex envelope of the pulse response.

PHASE SYNCHRONIZATION INFORMATION SIGNAL IN SINGLE-FREQUENCY NETWORKS TRANSMITTERS OF DIGITAL TV BROADCASTING DVB-T2 STANDARD
Article is devoted to the problem of synchronization information signal transmitters in single frequency networks for digital TV broadcasting DVB-T2 standard. It is noted that at the transition from local broadcast to broadcast in SFN synchronization problems transmitters. Proposed a method of providing a phase synchronization information signal network SFN transmitters. The method presented in the form of an algorithm settings transmitters having a significant time delay spread information signal transmitters in the modulators exciters, as well as its possible delays in the communication channels from the Center to the multiplexing in the inputs of exciters.
