Abstract
For the implementation of solutions for the creation of the Russian part of the space segment of the international COSPAS-SARSAT satellite navigation “Cicada” in the form of additional payload was installed radio complex search and rescue sex workers, which were in demand weight and size provisions incorporated in the design documentation satellite. According to the original plan were intended to implement the idea of  autonomous radio-orbits and calculate their own airborne satellite ephemeris “Cicada” for radio signals of terrestrial beacons. For this purpose satellites “cicada” was supposed to equip the receiving instrumentation measuring natural radial pseudo from the Doppler shift of the received satellite radio, as well as equip-board digital computer. Besides the obvious significant reduction of load on the ephemeris support NFC, with would open the possibility of further improving the accuracy of low-altitude navigation satellite ephemeris of “Cyclone” and “Cicada”, and therefore the accuracy of navigation field produced by these satellites.

Abstract
The main direction ofthe development of space systems for Search and Rescue (XPS) is the creation of a space segment based on satellites in medium [1]. At present, work in this area of intense research in Russia, USA, Canada and Europe. In 2000, the United States, the European Commission and Russia have begun consultations on the possibility of creating a system based on MEOSAR navigation satellites in medium-GPS, GLONASS, Galileo, and the use of this system in the COSPAS-SARSAT system.

Eminov R.A.

Abstract
The carried out survey of existing scientific sources have shown, that effect of atmospheric aerosol on delay of GPS signals is estimated non-properly. The new formulae for calculation of effect of atmospheric aerosol on GPS signal’s delay have been derived. The method for experimental determining of effect of aerosol on delay of GPS signals is developed.

The influenceof the dispersion length and polarization mode dispersion on the determination of the permissible length of the amplifier section

Grigorian A.K., Moscow Technical University of Communications and Informatics (MTUCI)

Abstract
The influenceof the dispersion length, taking into account the polarization mode dispersion on the permissible length of the amplifier section at high speeds. It is shown that when the chromatic and polarization mode dispersion, the dispersion length and allowable length reduces the amplifier section. But mode dispersion must be considered when determining the number of amplifiers, dispersion compensators, and other elements that affect the value of the polarization mode dispersion. After this calculation should adjust the distance between the amplifiers on the line, while shortening the length of repeater stations will be insignificant.

Filters on superficial acoustic waves with a combination of single-modeand two-mode sections

Orlov V.S.

Abstract
Structures of filters on superficial acoustic waves (PEAHENS) with small brought losses with a combination of elementary ladder or balancing and bridge sections on resonators (LDR or BBR) and two-mode sections on the longitudinally connected resonators (LCR) are described. Such combinations of mode and two-mode sections allow to ensure functioning of filters on PEAHENS both for intermediate, and for bearing frequencies at axial or balancing loadings of 50_300 Ohm, to realize small brought losses of IL = 2,3-3,8 dB without use of additional chains and to increase attenuation in an obstacle strip to UR = 55-70 dB in a wide strip of frequencies. Problems of coordination of elementary sections for the purpose of reduction of distortions owing to reflections are investigated. Examples of filters on PEAHENS with LDR_LCR_LDR structures are described; LCR-LDR-LCR; LCR-BBR-LCR; LDR-BBR on frequencies 442, 484, 135, 105 and 160 MHz respectively.

Abstract
The Russian company T8 developed 100 Gbit/c first in Russia with a transponder “Volga” with the parameters of quality of a signal best in the world (demanded OSNR of 12,5 dB) and record-breaking importance of electronic compensation of dispersion (75000 ns/nanometer). High quality of the equipment is confirmed with successful transfer of 100 Gbit/c with on 4000 km without dispersion compensation in the 80th channel DWDM system. “Volga” in heterogeneous DWDM networks in common c channels of 40 and 10 Gbit/c is shown by possibility of work of 100 Gbit/c from transponder. Creation of the Russian equipment with the parameters of quality of a signal best in the world (demanded OSNR) and competitive prices opens ample opportunities for development of speed of 100 Gbit/c with the Russian communications service providers.

Abstract
Currently, the IMS architecture is one of the most distributed information systems, including different levels of interaction, while ensuring the integration of various applications. At the base of IMS is the interaction of various components through protocols of different levels and an efficient distribution of functions between components. One of main IMS’s function is assignment of open environment for fast service delivery and implementation of them independent of applying access technologies and services. One of IMS’s elements is service broker. The functionality of a service broker is directed to manage service capabilities and arrangement of interaction between any type of IMS application servers. However, all the problems of service interactions and service provisioning are not solved yet and Service Brokering function as currently being studied by the 3GPP and Service Broker Forum. In this paper the evolution of Service Broker functionality proposed in standards, aspects of architecture and application interaction scenarios are examined, as well as a description of service broker products from different vendors is given.
