- 2. BANGABANDHU SATELLITE- 1Page 2 BANGABANDHU SATELLITE- 1 “Morning shows the day” the famous English saying is rightfully evaluated by Bangladesh, a newly born country located at South East Asia. Bangladesh has shown great promises since its liberation in 1971 from Pakistan. Following its own footsteps now Bangladesh has entered into the space to show how potential this country is. It is a very historical and exciting moment for the entire nation of Bangladesh to watch its very first satellite taking off for Space successfully. This telecommunications and Broadcasting satellite is targeted to narrow the digital divide, as it will take broadcasting and telecommunication services to rural areas and introduce profitable services, including direct-to-home services, across the country and over the region. The Satellite itself: The Bangabandhu Satellite-1 is the first Bangladeshi geostationary communications and broadcasting satellite. It was manufactured by Thales Alenia Space and launched on May 11, 2018. The project is being implemented by Bangladesh Telecommunication Regulatory Commission (BTRC) and was the first payload launched by a Falcon 9 Block 5 rocket of SpaceX.

However, the rocket carrying the payload triggered an automatic abort as it entered internal power and control at T-58 seconds. Soon after the rocket launch was pushed back 24 hours and it was finally launched on May 11, 2018. Bangabandhu- 1 launched from Kennedy Space Center on Merritt Island, Florida, USA. The historic event took place at 2:14am Bangladesh time when the country's first geostationary communication satellite started its voyage towards orbit. After launching the satellite Bangladesh began to receive test signal from it on May 12, 2018. Fig. 2: The Launching event. Behind the scene: The Bangabandhu-1 satellite was initially planned to be launched on an Ariane 5 rocket on 11 December 2017 to celebrate Victory day of Bangladesh. Following the lack of firm guarantee from Arianespace for that date BTRC chose Falcon 9 launch vehicle instead. It is named after the father of the nation Bangabandhu Sheikh Mujibur Rahman. 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. Bangabandhu Satellite-1 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.

The satellite will expand Ku-band coverage over all of Bangladesh and its nearby waters including the Bay of Bengal, Nepal, Bhutan, Sri Lanka, the Philippines, and Indonesia. This is coupled with C-band coverage for all aforementioned areas. Fig. 3: Location of the Bangabandhu Satellite- 1. Ground Control System: Bangabandhu Satellite- 1 utilizes ground control stations built by Thales Alenia Space with its partner Spectra in Betbuni, and Gazipur. The satellite is based on the highly secured and reliable Spacebus-4000B2 platform. Bangladesh Government formed a Government owned Bangladesh Communication Satellite Company Limited (BCSCL) with the aim to operate the Bangabandhu Satellite-1.

The major applications of the spacecraft include DTH, very small aperture terminal (VSAT) communications, backhaul and trunking, network restoration, and disaster preparedness and relief. The primary service area (PSA) of the satellite will be Bangladesh and neighbouring countries, while its secondary service areas (SSA) will include South East Asia, Europe, Middle East and North Africa (MENA), as well as East Africa. Prospects and Challenges of the Satellite: The launch of satellite Bangabandhu- 1 by Bangladesh brings both prospects and challenges as it is expected to help the country save foreign currency while the challenges remain in effectively running the venture, experts. BTRC officials have confirmed that the expenses of the satellite would return within seven years of its service as it would provide service for television channels, mobile phone companies, TV service providers, internet connectivity in remote areas and for weather forecast. Besides foreign currencies could be earned by selling capacity of the satellite’s transponder to other countries along with saving foreign currencies spent by the countrie’s TV channels for hiring satellite transponders from others. As per the government estimation the country would be able to earn $1 billion in 15 years by leasing out transponders and another $1.5 billion by selling other services to different countries. Experts however assumes that making the project profitable would not be that much easy considering the existing structure of the company, Bangladesh Communication Satellite Company Limited, formed to operate the satellite. How will Bangladesh be benefited by the Bangabandhu satellite? This satellite will bring enormous development and uninterrupted telecommunication system in Bngladesh especially in Television, Telephone & Internet service which Bangladesh usually purchases from from overseas. At present Bangladesh is spending annually more than $14 million on satellite rent to ensure connectivity of TV, radio, telephone and internet. So this satellite will make Bangladesh self contained & Bangladesh will also earn some foreign currency by broadcasting service.

So Bangladesh rent service to Nepal, Myanmar or Bhutan and may earn more than $50 million per year. Finally communication system of Bangladesh will get new progression of development. This satellite will give Bangladesh a long term service to a large scalability, global availability, reliability, versatility & super performance. Some sectors like telemedicine, e- learning, e- researches, video conference, defence & disaster management system will be improves for this satellite in Bangladesh.
