Bangabandhu Satellite Composition (PDF)

Bangabandhu Satellite Composition : Introduction: The whole world is advancing with a lot of modern contributions of science and technology. Today almost all the modern and enlightened nations have their own satellites in the orbit. A sovereign country, in pursuit of sustainable development, needs its own satellite in order to reduce its dependency on other nations. With that mission Bangladesh launched its first ever satellite on 11 May 2018 on a Falcon 9 rocket. Through the launch, Bangladesh has not only got a major milestone in scientific research of the country but also a big step towards achieving self dependency.

What Satellite is: A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth. Usually, the word “Satellite” refers to a machine that is launch into space and moves around Earth or another body in space. Earth and the moon are examples of natural satellites. Thousands of artificial or man made satellites orbit Earth.

Some take pictures of the planet that help meteorologists predict weather and track hurricanes. Some take pictures of other planets, the sun, black holes, dark matter or far away galaxies. These pictures help scientists better understand the solar system and universe. Still other satellites are used mainly for communications, such as beaming TV signals and phone c around the world.

Why Satellites are Important: The Brid’s-eye view that satellites have allows them to see large areas of earth at one time. This ability means satellite can collect more data, more quickly than instruments on the ground. Satellites also can see into space! better than telescopes on Earth’s surface. That’s because satellites By above the clouds, dust and molecules in the atmosphere that can black the view from ground level.

Without satellites, TV signals do not go very far. TV signals only travel in straight lines. So they will quickly trail off into space instead of following earth’s curve. Sometimes mountains or tall! buildings will black them. Phone calls to far away places were also a problem. Setting up telephone wires over long distances or underwater is difficult and costs a lot. With satellites, TV signals and phone calls are sent upward to a satellite. Then, almost instantly, the satellite can send them back down to different locations on Earth.

Background of Satellite in Bangladesh: A country like Bangladesh is highly exposed to natural disaster risk because of its unique geographical location. Telecomunication system in Bangladesh has always been suffering from interruptions. and problems as erratic disasters hit the country. During such emergency situations satellite network can play an important role in ensuring uninterrupted telecommunication services in Bangladesh. With that vision, BTRC started working to open new dimension of Posibility in the telecommunication sector of Bangladesh by launching its first ever satellite.

It had a long cherished dream of having country’s first satellite. In order to materialize(103) the dream, BRTC formed a committee in April, 2008 which was then reformed in January, 2010. This committee performed various important activities and maintained a continuous liaison (M) with ITU to perform all secretarial jobs in the regard. Every member state of ITU has to follow ITU regulations in order to launch his satellite.

Recognizing the importance of the satellite launching preparatory Activitics, BTRC formulate a project with the title “Preparatory Functions and Supervation in Launching a Communication and Broadcasting Satellite which was then approve by the government on 26 January, 2012 with an estimate project cost of Tk 8681.51 lakh for till 2015.

Baseline Characteristics of the Country’s First Satellite: Bangladesh has planned to launch a Communication and Broadcasting satellite consisting 24 ku and 16 c-band transponders. The priority satellite applications are Direct to Home (DTH), VSAT, Backhaul and Trunking, Network Restoration, Disaster Preparedness and relief etc. The Primary Service Area (PSA) would be Bangladesh and neighboring countries and the Secondary Service Area (SSA) would be South East Asia, Europe, MENA and East Africa depending on orbital slot.

The system concept of the proposed satellite comprises with satellite Playload requirements, orbital slot/frequences, coverage areas, ground segment, user terminal design characteristics, satellite operations and environment factors. There are two ground stations for satellite operation; control one as the primary site and other as the backup site.

Buying Slot and Launching Bangabandhu Satellite : Bangabandhu Satellite-1 carries a total of 40 Ku-band and C band transponders with a capacity of 1600 megahertz with a predict life span of 15 years. The satellite is currently locate at longitude 119.09″ E and is expect to be locate at 119.1° East longitude geostationary slot. Initially the BTRC applide for a slot on 102 degree East to the International Telecommunication Union (ITU). However, nearly 20 countries include USA, Russia, France and Australia raised objections that their satellite communication would be disrupt if Bangladesh was given that slot.

Bangladesh bought the slot on 199.1 degree east from Intersputnik, a Russian satellite for $28 million. The satellite was suppose to be launch in December 2017 but hurricane Arma had a devastating damage on Florida and made its launch delay from Cape Canaveral. Bangabandhu Satellite 1 was Reschedul (after some changes of scheduled dates) to be launch on 11 May 2018 and Bangladesh’s dream of launching its first satellite came true on that day. After launching the satellite, Bangladesh began to receive test signal from it on 12 May 2018.

How the Bangabandhu Satellite will Benefit Bangladesh: The Bangabandhu Satellite will bring enormous development and uninterrupted (f) telecommunication system in Bangladesh especially in television, telephone and internet services which Bangladesh has purchased from overseas. At present Bangladesh is spending annually more than one $ 14 million on satellite rent to ensure connectivity of television, radio, telephone and internet. So this satellite will make Bangladesh self Contrained and Bangladesh will also earn some foreign currency by broadcasting service.

Bangladesh may rent service to Nepal, Myanmar, or Bhutan and may earn more than $50 million per year. Communication system of Bangladesh will get new progression of development. Some sectors like telecommunication, e-learning, e-research, video-conference, Defence and disaster management system will be improve, for this satellite and this service will give Bangladesh a long term service to a large scalability, global availability, reliability, versatility and super performance.

Conclusion: India and Pakistan have their own satellites and another Neighbouring country, Sri Lanka is in queue. So the introduction of satellite in Bangladesh is expect to help Bangladesh to advance in communication sectors and help Bangladesh for earning foreign currency by renting its facilities to other Neighbouring countries where there is no satellite.
