owner of SES-5 is a Dutch satellite operator SES World Skies.The satellite was designed to provide communication services to countries in Europe, the Baltic States and Africa.It weighs 6,000 kg, and is designed for a period espluatatsii at least 15 years.
devices that send a signal in response to a received signal, called transponders.They are used to form a channel satellite communications system of identification "friend or foe" and determine the distance to an object in sonar.
The satellite SES-5 is set 36 Ku-band transponders and 24 - C-band.Ku-band is in the range of centimeter length radio waves from 1.67 to 2.5 cm (12-18 GHz).These frequencies are given paid satellite TV (DTH) broadcast with a zone in the Baltic States, Scan
dinavia and Africa.
wavelength range from 3.75 to 7.5 cm is called the C-band.In North and South America it is this range is essential for satellite television.On the SES-5, these frequencies will be used for communications GSM, maritime communication and video transmission.
In addition, Dutch satellite performs certain tasks EGNOS - the European Geostationary Navigation Overlay Service.The service is designed to improve the quality of systems GPS, Galileo and GLONASS.It consists of a master station, which collects information from satellites GPS, Galileo and GLONASS, a network of ground relay stations and geostationary satellites, EGNOS, which transmit information to receivers GPS.
Commissioning geostantsionarnogo telecommunications satellite SES-5 will improve the quality and reliability of information transmission.Increase the coverage area of TV signals and signals GPS.However, because in Russia there is no ground stations EGNOS, all favorable change notice mostly residents of the western part.
