The Bangabandhu Satellite-1 (Bangabandhu-1) is the first Bangladeshi geostationary communications and broadcasting satellite. It is named after the father of the nation, Bangabandhu Sheikh Mujibur Rahman. It was manufactured by Thales Alenia Space and launched on 12 May 2018.[1] The satellite was the first payload launched by a SpaceX Falcon 9 Block 5 launch vehicle.[2] Bangladesh became the 57th country

to possess an independent satellite in space with the launch of 'Bangabandhu-1'.[3]

Background

The project is being implemented by Bangladesh Telecommunication Regulatory Commission (BTRC) in 2008 working hand-in-hand with US-based Space Partnership International, LLC. The government-owned Bangladesh Satellite Company Limited, BSCL (Formerly known as Bangladesh Communication Satellite Company Limited, BCSCL) was formed with the aim of operating the satellite.[4]

The satellite expands Ku-band and C-band coverage over all of Bangladesh and its nearby waters including the Bay of Bengal, Nepal, Bhutan, Sri Lanka, the Philippines, eastern Indian states (West Bengal, Assam, Meghalaya, Mizoram, Tripura, Nagaland, Arunachal Pradesh) and Indonesia.

Bangabandhu-1 was initially planned to be launched on an Arianespace Ariane 5 ECA rocket on 16 December 2017 to celebrate the Victory day of Bangladesh. Following the lack of firm guarantee from Arianespace for that date, BTRC instead chose the Falcon 9 launch vehicle.[5] The satellite is now located at the 119.1° East longitude geostationary slot.

Construction

Bangabandhu-1 was designed and manufactured by Thales Alenia Space. The total cost of the satellite was projected to be 248 million US dollars in 2015 (Tk 19.51 billion), financed via a $188.7 million loan from HSBC Holdings plc.[6] The satellite carries a total of 40 Ku-band and C-band transponders with a capacity of 1600 megahertz and a predicted life span to exceed 15 years.[7][8][9][10]

Launch

Bangabandhu Satellite-1 was launched at 20:14 UTC on 12 May 2018,[1] on a SpaceX Falcon 9 launch vehicle at the Kennedy Space Center, USA.[11] It was the first payload to be launched using the new SpaceX Block 5 model of the rocket.[12][13]

The satellite was originally planned to launch on 10 May 2018, however the rocket triggered an automatic abort as it entered the startup phase of terminal count at T-58 seconds. The rocket launch was pushed back 24 hours, and it was finally launched on 11 May 2018.[14]

The satellite uses ground control stations built by Thales Alenia Space with its partner Spectra primary ground station in Gazipur. Secondary ground station is at Betbunia, Rangamati[15] The first test signal after launch was received by the operators on 12 May 2018.[16]
