What is GISS?

2.6 Global Transport Information Telecommunication IP Network

Purpose — duplicates and supplements the channels of submarine and terrestrial cable of a information and telecommunication lines (FOCLs) of interested operators.

All operators call the shortest distance and, accordingly, the minimum signal delay (RTD) the most important factor in the premium quality of their route between Europe and Asia.

In accordance with a certain stage of development, the transport information and telecommunication IP-network GISS, containing 144 or 288 on-board switches-routers of IP flows, interconnected by four inter-satellite communication lines with a throughput of at least 20 Gbps each, is capable of providing the total throughput of the interregional and international traffic of 2.880 Gbps minus about 800 Gbps required for the delivery of radar monitoring data from remote points of the globe.

At the same time, choosing the shortest delivery routes with minimal time delays, GISS has an advantage over territorial FOCLs.

Speed of input/output of IP traffic from any of 72 (144, 288) territorial communication zones (collective access) up to 2 Gbps through X-access terminals as part of base stations of telecom operators and up to 4-6 Gbps from stationary regional point for receiving and processing radar information.

In order not to interfere with the broadband access subsystem, for the introduction of IP traffic into the space transport network from the ground terminals of telecom operators, separate receiving paths can be created on board the spacecraft using antenna elements of the receiving AA in the extended range of 8650—8800 MHz or an additional APA in X ( 3.0 cm — 9.3—9.9 GHz) range (see Fig. 2 bottom right).
