This paper presents the key organizational aspects of the project, which are non-traditional in domestic practice. The project is being developed cooperatively by home enterprises headed by RSC Energia with the participation of leading forcing manufacturers NEC (Japan) and DASA (Germany). The state customers are RSA and Russian Satellite Communications Company (RSCC). The investor as well as prime contractor for the payloads is JSC Gascom. The Yamal satellites provide the United Communication Network (UCN) of RF, and service provision in the world market of satellite communications services. The principles of succession with the existing national \"Horizont\" and \"Express\" networks are mentioned, along with key features of the satellites, and main parameters of the payloads. In their manufacturing they use modern engineering solutions and parts, which allow us to achieve the same characteristics as the best foreign satellites. The service zones are shown, maximally adapted to RF territory to allow the provision of high-quality services. The paper contains the capacity characteristics and the list of services to be provided by Yamal satellites, the parameters of the communications and TV ground stations to support the mentioned traffic, and the key features of Yamal satellites in comparison with foreign analogues.","PeriodicalId":240115,"journal":{"name":"3rd International Conference on Satellite Communications (IEEE Cat.

An overview is given which details the activities at Dornier Satellitensysteme GmbH for improved TWTA for future satellite transponders. The mission of the GALS R16 spacecraft is the support of the Russian Ku-band TV network which allows simple and low-cost on-ground subscriber units using antennas of 60 cm to 90 cm diameter. This requires a satellite EIRP of 51 dBW. To achieve the required radiated field strength, travelling wave tube amplifiers (TWTA) at power levels of 100 W at the end of life (EOL) are used in the 24 transponder channels (4:6 redundancy). Common design activities of JSC INFORMCOSMOS, SPAR Aerospace and Dornier Satellitensysteme GmbH led to a TWTA design which meets the Russian spacecraft requirement and achieves the most perfect features achieved during recent space programs executed by Dornier. Additional transponder equipment as waveguide isolators and switches are built by COMDEV Canada and supplied by SPAR Aerospace. The TWTA are designed, integrated and tested by Dornier using TWTA supplied by TTEG (former AEG) Germany and electrical power conditioners (EPC) developed, space-qualified and manufactured by Dornier Satellitensysteme GmbH, Germany.","PeriodicalId":240115,"journal":{"name":"3rd International Conference on Satellite Communications (IEEE Cat.

It takes the best of DAMA (demand assigned multiple access), TDMA (time division multiple access) and SCPC (single channel per carrier or point-to-point) technology and fills a niche application that the other three technologies cannot. SkyFrame is ideal for small to medium size corporate networks that require cost effective efficient support of both voice and data. SkyFrame, unlike the other three technologies, is frame relay based, and as such it is ideally suited to the \"bursty\" nature of LAN traffic. This cannot be said for the other three technologies. SkyFrame is designed to bridge the gap between small and large networks that have a mix of voice and data. Current star/TDMA and mesh/DAMA offerings cannot economically scale down to small-and-medium size networks. SkyFrame addresses the low-end TDMA and DAMA market while addressing all of the SCPC market; both low and high-end applications.","PeriodicalId":240115,"journal":{"name":"3rd International Conference on Satellite Communications (IEEE Cat.

These cases include identical output in the beam or in the entire transponder satellite when the altitudes are different, and the apertures of the onboard multibeam antennas are identical or when the beam partial areas on the surface of the Earth are identical. The parameters mentioned, in their turn, determine the relationship of the power-mass characteristics, and, accordingly, costs of creating the orbital groupings. By comparing the latter with the capacities, it becomes possible to comparatively evaluate the specific costs for the transmission of an information unit, depending on the orbital altitude, number of satellites in the system, and the beams of the transponder-satellites.","PeriodicalId":240115,"journal":{"name":"3rd International Conference on Satellite Communications (IEEE Cat.
