Bangabandhu-1: First Satellite of Bangladesh

Bangabandhu-1 is the first Bangladeshian geostationary communications satellite . The satellite was ordered in November 2015 from Thales Alenia Space, who will build, launch and operate the satellite for the Bangladesh Telecommunication Regulatory Commission (BTRC). It will be stationed at an orbital slot at longitude 119.1° east with 40 transponders (Ku and C-band) with a capacity of 1600 megahertz. The total cost of the satellite is 248 million US dollars (Tk 19.51 billion).

Bangabandhu-1 is a satellite telecommunications system, comprising a satellite and the complete ground segment (control, mission and user segments). Thales Alenia Space is also in charge of building two facilities in Bangladesh for all ground support equipment needed to control the satellite and operate the telecom system. There will be two ground stations for satellite operation and control, one as the primary site (Gazipur) and other as the backup site (Betbunia). Thales Alenia Space Belgium, Thales Alenia Space Italy and Thales Alenia Space Spain are all involved in this project, as suppliers of various ground and satellite components.

Once the satellite is launched, Bangladesh is expected to save $14 million annually and earn around $1 billion by leasing and renting the satellite. There will be a huge improvement in various sectors including information communication, e-learning, healthcare as well as early warning system and emergency relief efforts during natural disasters. Over 150 channels with high-definition quality will be available in the country as well.
