Thales Alenia Space will build the satellite called Bangabandhu-1 for the Bangladesh Telecommunications Regulatory Commission (BTRC) to be launched into space in 2017.
BTRC chairman Shahjahan Mahmud said the contract was worth 19.51 billion taka (USD 250 million).
Junior telecoms minister Tarana Halim hailed the deal which would save Bangladesh coffers USD 14 million a year from renting transponders of foreign satellites.
"With the launch of Bangabandhu-1, Bangladesh will become the 57th member of the exclusive club of satellite- owning countries," Halim said at the contract-signing ceremony in the capital.
"The satellite will cover Bangladesh, other South Asian countries, Indonesia, the Philippines and several other nations," the minister added.
Early this year Bangladesh bought a satellite orbital slot from Russian company Intersputnik International for USD 28 million.
