List of geostationary satellites |
SGDC (Satélite Geoestacionário de Defesa e Comunicações Estratégicas) is a communications satellite operated by the Brazilian Telebras . It is the first satellite for the Brazilian government as well as the first spacecraft launched by Arianespace for Visiona Tecnologia Espacial SA, the main contractor responsible for program management, overall system integration and end-to-end communication.
He was born on May 4, 2017 at 19:50 UTC with an Ariane-5 - rocket from the rocket launch site Guiana Space Center (along with Koreasat 7 ) into a geostationary brought orbit.
The three-axis stabilized satellite with 50 Ka-band - and 7 X-band - transponders equipped and will supply 75 degrees West from South America with telecommunications services with up to 57 Gbps of position. The Ka-band payload offers a range of high-performance beams that are entirely focused on Brazilian territory, while the X-band system includes South America and neighboring maritime regions. SGDC is intended to be used in both civilian and military terms, enabling a secure satellite communications system for the Brazilian government and armed forces while reducing the digital divide in Brazil. The satellite was built on the basis of the Spacebus 4000C4 satellite bus from Thales Alenia Space and has a planned service life of more than 18 years.
