Promising prospects for the transition to integrated broadband information technologies in the 21st Century i.e. B-ISDN, B-Internet, multimedia services etc. are dependent on the development of ATM. Impressive results concerning the establishment of high-speed ATM transport lines, platforms and fixed access networks with centralized architectures have already been achieved. However centralized ATM architectures are used mainly in transport and corporate networks as their cost is unacceptable for deployment in mass public networks. The key problem on the way to integrated broadband ATM public networks is the implementation of inexpensive distributed ATM systems for access to broadband integrated services. Active elaboration of such 3rd generation wireless (WLAN) and mobile broadband (MBS, WATM) systems with radio coverage of highly urbanized local areas is being conducted within the framework of the European ACTS Program. The universal adaptive method of ATM access to various hyperlong media and efficient methods concerning dynamic control of bandwidth distribution, traffic parameters and service quality which provide an increase in radio coverage up to the size of metropolitan (MAN), wide-area (WAN) and satellite (GM PCS) networks are discussed. The architectural basis of universal multifunctional ATM networks for subscriber access to B-ISDN, B-Internet, multimedia services on radio, optical, optical-fiber and satellite channels with flexible and distributed architecture is developed on the basis of the proposed methods.","PeriodicalId":240115,"journal":{"name":"3rd International Conference on Satellite Communications (IEEE Cat.

It was developed for the \"Bankir\" satellite communication and data transmitting system of the Central Bank of Russian Federation. The spacecraft was designed on the basis of the Lavochkin satellite communications. That has led to a decrease in terms of development and tests, cost of the spacecrafts and the entire communication system as well. The covering zone is formed by three S/C of the orbital system, each of them having on-board retranslation complexes (BRTK) working in Ku-band (14/11 GHz). Active phased antenna grids (AFAR) that can form up to 16 narrow receiving-transmitting beams, that can be retargeted to any undersatellite point in the limit of the S/C viewing area, are used, giving a possibility of changing the covering zones in the limits of the viewing area and to have flexible redistribution of the retranslator working ability. S/C injection into the staying points is performed by the three-staged \"Proton\" launch vehicle with the upper stage \"DM\" from the Baikonour launch site. In order to solve tasks of the on-board systems and also to perform control, diagnostics and recovery of the on-board systems, there is an on-board control complex (BKU), and in order to provide normal functioning of the BKU and BRTK for the execution of the input before the S/C tasks, there is an on-board control complex of service systems (BKOS).","PeriodicalId":240115,"journal":{"name":"3rd International Conference on Satellite Communications (IEEE Cat.

The main objective of these breadboards is to serve as development tools for receiver signal processing research in view of the scientific applications of GNSS. Some of these applications will be realised by means of receivers embarked on satellites in low Earth orbit (LEO) as part of on-going and future ESA programmes and will include precise orbit determination, radio occultation measurements and measurements of the parameters characterising GNSS signals reflected at the sea surface. During an occultation measurement the GNSS signal propagation encounters a challenging environment. Not only substantial Doppler dynamics occur during a measurement due to the effect of gradients of the refraction index, but also attenuation and deep fading caused by multipath propagation. The signal tracking requirements for space applications are analysed and applied to the hardware and software tasks. Resultant enhancements to the receiver digital processing are presented along with their impact on the intended application. The areas of concern are the acquisition and tracking of signals in high dynamics and at low carrier-to-noise ratios (CNR), and on improving the performance of tracking the GPS P code without full knowledge of the spreading code.","PeriodicalId":240115,"journal":{"name":"3rd International Conference on Satellite Communications (IEEE Cat.
