country' first artificial satellite 'Bangabandhu Satellite-1' was launched successfully on Friday at 2:14 pm. Bangabandhu satellite-1 launches as the 57th country, the country's satellite network is added to the elite club of the country.
Satellite is an artificial object used as an information gathering or a means of communication that is placed in orbit around the Earth or the Moon or any other planet. Thousands of such satellites revolve around the Earth's orbit. Some of them collect pictures of different planets, some are also helping weatherers predict various natural disasters, including predicting weather, orbiting orbiting other planets, suns, black holes or distant galaxies. There are also some satellites that are used mainly as communication medium such as TV Signals, phone calls connectivity around the world. More than 20 satellites are used in the GPS system.
The satellites can be different shapes. There are two common parts of each satellite. Antennas and energy sources. Antenna receives data collection and collection. Both solar panels or batteries can work as energy sources. Satellite cameras and some sensors are also fitted. There is a separate space to set up satellites in orbit. It is called "Launch Vehicle". There are two types of launchers - waste rockets and space shuttle. Based on the orbit, the satellite system can be divided into several groups. LEO (Low Earth Orbit) - 160-2,000 km from the surface of the Earth Located above Generally, the observation of satellites in the Earth is in this orbit. MEO (Medium Earth Orbit) - 20000 km from Earth's surface Located above Generally, GPS satellites are in this orbit. GEO (Geostationary Earth Orbit) - GEO 36,000 km from Earth's surface Located above Antenna's position in this orbit is fixed. It is commonly used in the transmission of radio and TV.
The location of Bangabandhu satellite is 119.1 degrees east longitude orbit. There are 40 transponders. Of these, foreign currency earnings are possible for use in 20 countries and 20 fares. Its footprint or coverage will extend from Indonesia to Tajikistan. Through the strong KU and C band, it will cover the whole of Bangladesh, SAARC countries, Philippines and Indonesia. The Bangabandhu satellite weighing 3.7 tonne was designed and made by French company Thales Alenya Space. And the rocket that is taking it into space has made it to the US SpaceX. Launchpad is from the Launchpad in Florida. After the first attempt was stuck in technical difficulties, the launch of 'Bangabandhu Satellite-1' spacecraft began on the second day after launching a rocket from Kennedy Space Center in Florida. The launch process will be completed in two stages. The first stage will take 10 days to complete and the second phase will take 20 days. It will take 8-11 days to go to orbit Satellites by passing the 35,776 km route from Earth station. And ready to be fully prepared in 3 months.
Bangabandhu satellite chief work to ensure satellite television service. This can be done with DTH or Direct to Home Dish Service. Apart from this, the satellite can be sure that the Internet connection will not be available in areas where the optical cable or submarine cable has not reached. It will be possible to expand the internet and telecommunications services through this satellite in remote areas of the country. A new dimension will be involved in tackling disaster situations and management. Apart from its own satellites, the reliability of global telecommunications will end. Bangabandhu Satellite-1 will also play an important role in telemedicine, e-learning, e-research, video conference, defense and emergency communication.

Note: It will take an estimated 4 months to take proper operation of Bangabandhu's related operations properly. No excuse will be created in the atmosphere of our country, because of various backgrounds, and the rest is hopeful of the destiny of the country's destinies. That is the only desire of all citizens to move forward in the country. I do not have any exceptions. This new path of Bangabandhu-1 will be beautiful. Thank you.
