Abstract

Satellite networks handheld earth stations are ongoing through the spacecraft in geostationary orbit, as a rule, with direct relay with frequency-division multiplexing (FDMA).

Transition to the standard DVB-RCS[1]. with a spatial frequency TDMA, involves placing on board a spacecraft multipath receiving-transmitting antenna and multi-board digital platforms standard DVB-RCS, providing multi-channel demodulation of earth stations. Using the DVB-RCS standard with MSF-TDMA can significantly extend the functional characteristics of mobile networks through satellites in geostationary orbit [2, 3, 4, 5].

To move to a higher rate of information transfer, adopted in satellite communication networks standard DVB-RCS, need to be more than an order of magnitude increase the energy potential of satellite radio links spacecraft , which can only be achieved through the establishment of on-board the spacecraft multipath receiving-transmitting antennas.

As a prototype under consideration DVB-RCS standard mobile satellite communication network creating issues with MSF-TDMA is used in the currently deployed in the X-band portable earth station network operating in the direct mode, the relay FDMA frequency division channels. Earth stations in the network, despite the relatively high functionality and power characteristics, to ensure a direct telephone connection to each other is forced to operate at the lowest possible data transmission speeds.

Modernization of communication satellites by the introduction of the multipath receiving-transmitting antennas allow to implement X-band-based earth stations, networks mobile satellite DVB-RCS (MSF-TDMA) standard, which will be provided by the possibility of organizing a high-speed direct connection of subscriber earth stations each other.

Proposed in the present work the modernization of communications satellites option by installing on-board the satellite multipath receiving-transmitting antenna implementing DVB-RCS standard with the space-time-frequency resource sharing, enables the creation of mobile satellite communication networks standard DVB-RCS through satellites in geostationary orbit.

For the practical implementation of these proposals in the paper version of the modernization of communications satellites greatest challenge is the creation of high-speed digital switches, a key element of the multipath receiving-transmitting antenna for satellites in geostationary orbit implementing zonal service.
