The invention relates to electronics and digital technology and can be used for telecommunications satellite organization using low-energy satellites.

Known satellite information system, which uses the transmission of data messages by the television channel through space relay station (see USSR author's certificate No. 1801249 A3, CL NW 7/185, 1991), consisting of a transmitting antenna, a transmitter, a local center formation information, the receiving antenna, the transmitting antenna, receiver, transmitter, data center, transmitting antenna, repeater, single time, receiving antenna, a receiver, a local cable television network, block allocation information signal, the television receiver.

A disadvantage of the known system is relatively low friendliness of the interface, resulting in lower efficiency of information exchange between subscribers due to the lack of a web service with chat robot [Menasce D., Almeida C. the Performance of web services. Analysis, evaluation and planning: TRANS. from English. - SPb.: Diasoftyup, 2003. - 480 S.] on the repeater, and also due to the lack of base station control device and control the web service.

Known cellular communication system having Nate the data, and space nodes, which are designed to service large areas (see EN 2100904, CL NW 7/185, NV 7/26. Mobile communication system - 1997.12.27). However, the disadvantage of this system is relatively low friendliness of the interface, resulting in lower efficiency of information exchange between subscribers.

Known technical solution (see patent No. 2005020282 B1, US, IPC 7 NW 7/185, 2005.21.01),including a system of navigation satellites, having in its composition a web service.

The disadvantage of this system is high enough friendliness of the interface, resulting in lower efficiency of information exchange between subscribers.

Closest to the presented application is a satellite communication system (prototype) (see EN 2121760, CL NW 7/185, 1998.11.10), consisting of an antenna, a low noise amplifier, a receiving device signal processing mdcr, PC, device processing basic information mdcr, device registration, driver signals FDMA equipment and transmitter.

The disadvantage of this satellite system is not high enough friendliness of the interface, resulting in lower efficiency of information exchange between subscribers.

Indeed, the subscriber system is forced to use text, graphics, or video materials, not the two who engaged in interactive and is not capable of adaptive responding subscriber. As a result, the perception of information less efficiently than it would be when interacting with an interactive automated adaptive interface, such as a chat robot, and others) is actually a man accustomed to communicate (exchange information) live (informational) dialogue, asking questions and getting answers. This increase in usability of web services increases the efficiency of information exchange between subscribers. And Vice versa - read text, graphics and other subscriber (especially those working in extreme conditions) heavier than a dialogue. Currently there is rapid development of web services [see Menasce D., Almeida C. the Performance of web services. Analysis, evaluation and planning: TRANS. from English. - SPb.: Diasoftyup, 2003. - 480 S.].

The technical result of the invention is to increase the efficiency of information exchange between people (users) by creating the interface of the web service.

This technical result is achieved by the fact that the satellite communication system according to the invention on the satellite repeater is a web service with chat robot on each workstation PC completed with chat robot and the base station PC is configured to the UE is Alenia web service and its control.

Web service with chat robot can coordinate system users and to bring them into line with the current needs of the system as a whole and the base station. For example, a web service can be put information about what information is needed at the moment, and which have become irrelevant. A known number of chat-bots (, and others), which is actually an interactive automated adaptive interface.

Chat robot is a software robot that is able to conduct a dialogue with subscribers of satellite communication systems on a given topic. The operations of the robot is the scenario, following which, the robot maintains a dialogue. In conditions of emergency activities of the subscriber he needs in a very short period of time to process a large amount of information, to adopt and implement the right solution, in addition, such conditions increase the accuracy requirements of the actions of subscribers, the speed of decision making against the background of emerging sensory, emotional and intellectual overload.

Chat-the robot starts when the user turned on the link posted on the web service. Each question of the subscriber and the answer is a chat robot is recorded in the minutes, but the conversation ends, will be available to the operator ground control station for reading.

Prompt the awn information exchange between subscribers increased by what is a chat robot will provide a web service interactivity, and, consequently, increase the friendliness of the interface. Often (especially in extreme circumstances) the subscriber is much easier and more convenient to have an interactive dialogue with the information system (chat robot)than to search the text, especially among a large number of text documents. This is especially important in conditions of high time pressure and high responsibility tasks. Thus, the chat robot will allow customers to quickly find on the web service information.

Chat robot can be used in the technical support services, as it will be able to answer frequently asked questions. In addition, if necessary, (or according to certain rules) im robot will forward the dialogue on the person at the Central station. Thus, significantly increases the efficiency of information exchange between subscribers of the satellite communications system.

Control device and control the web service is connecting element and is necessary for specific web services on the satellite repeater, and provides oversight and technical support for web services.

The implementation of the claimed invention is explained using the drawing.

The drawing shows a structural diagram of a satellite communication system.

On Board of the satellite repeater 10 additionally introduced web service with chat robot, in which is placed the actual information about what information is needed at the moment, and which have become irrelevant. In turn, subscribers workstations browse the web service using the chat robot, and get actual information about how they can adjust their work in accordance with the changing requirements of the base station 2.
