Hello all of my friends.The first Satelite of Bangladesh has successfully lounced..I am going to discuss about it..So lets start
Bangladesh has emerged as the world's 57th satellite operator with the launch of 'Jai Bangla Joy Bangabandhu' satellite launched in space, last night.
The satellite's successful launch was started from the launch pad of Kennedy Space Center in Florida on Friday at 4:14 pm (Friday, 2-14 May) during the United States local time. The United States's private space exploration and technology company SpaceX's Falcon-9 Rocket moved to space with the communications and broadcast satellite. After approximately 33 minutes of launch, the satellite carrying the satellite entered the orbit.
The satellite will expand beyond Indonesia, from Indonesia to Tajikistan. After the Padma bridge, Bangabandhu satelite is the second pride of the country.
The satellite's uprising scene spaceside directly broadcast on their website. In the wake of the night, along with television channels, a large screen was installed in different parts of the country including the capital city. This historic moment has been witnessed by all the people of the country. This launch scene was arranged by the district administration, including the Prime Minister's Office.
Many Bangladeshis living in different countries of the world have witnessed live broadcast of this satellite launch.
After successful launch of 'Bangabandhu-1' satellite, Prime Minister Sheikh Hasina announced her good launch in the television address.
A Bangladeshi delegation led by Prime Minister Sheikh Hasina's son and her information technology advisor Sajeeb Wazed Joy witnessed this satellite launch in Florida. About 7 minutes satellites are visible in the clear sky in Florida.
State Minister for ICT related issues Junaid Ahmed Palak said, "I want to commemorate Father of the Nation Bangabandhu Sheikh Mujibur Rahman today, who initiated the process of entering the space age in 1974 by establishing the first satellite earth station in the country. "He said, the example of technological transition of Bangladesh under the leadership of Prime Minister Sheikh Hasina was launched by Bangabandhu-1 satellite launch.
State Minister Palak said, "Bangabandhu-1 is a timely initiative of Prime Minister Sheikh Hasina, which has a vision of building Digital Bangladesh by 2021. '
Earlier, State Minister Tarana Halim said that the carrying rocket carrying Bangabandhu-1 satellite would be 119.9 degree East longitude in Orbital slot for rent in Bangladesh.
The officials said that Thales of France created three thousand 700 kg weight, including the energy generated by the Allenia Space. The satellite's orbital space is 36,000 kilometers above. Due to air traffic, it will take eight to 12 days to reach the specific location of the orbit. Then the satellite will be able to fully reach with two ground stations built for control from Bangladesh. It may take another three months to go to commercial activity.
For the management of satellite, a company named Bangladesh Communications Satellite Company Limited has been formed. The current manpower of the company is 35 people, including 18 engineers. For the control of the satellite from the land, two 'Ground Station' has been constructed in Joydebpur of Gazipur and Betaniya of Rangamati on the land owned by Bangladesh Telecommunication Company Limited (BTCL).
Bangabandhu-1 is a full commercial communication and broadcast satellite. For this, the expenditure is Tk 2,776 crore. Of this, the cost of constructing the satellite is Tk 1,900 crore. Its validity is 15 years.
Regarding the kind of services the country will receive from this satellite, the officials said that there will be 40 transponders, 14 c and 26 KU bands. 20 transponders will be used for Bangladesh and the rest will be rented. These satellites will reduce foreign-dependency. Currently, foreign satellite rental costs around $ 14.4 million each year. The money will remain in the country if its own satellite.
In addition, it will be easier to extend the broad-based service to remote areas. Global telecommunications will end in relation to dependence. DTH, Video Transmission, VSAT, Private Network, Point-to-Point Connection-these services will be easy. There will be a lot of improvement in the management of defense and disaster management and the government will also play a role in increasing revenue earnings. Apart from this, Bangladesh will advance in the field of technology to be included in the world's elite countries.
State Minister for ICT Junaid Ahmed Palak said, "Bangabandhu satellite will serve in three categories. Broadcasting, telecommunication and data communication services make unprecedented progress in Bangladesh's telecommunications sector. '
Earlier, a satellite launch was scheduled to be held in the local time of Florida on Thursday at 5:47 pm (3:45 pm on Thursday). All the process was finished with the installation of satellites in rocket and with fuel. Falcon-9 began to smoke out a few minutes before the scheduled time of launch. But in the last minute, due to mechanical error, the launch was postponed.
The satellite was supposed to launch at any time between 4 pm and local time at 6 pm 22 minutes (Thursday, Thursday, 02 to 12 minutes, 4 minutes, 22 minutes). At one stage, SpaceX local time sets the launch time at 4:42 pm (Bangladesh Time Thursday 2-4-2012) on launch time. Later, an hour later, at 5:47 am (3:00 pm on Thursday in Bangladesh time) was reported at the launch. But that night did not stop waiting.
After the postponement of the day, Prime Minister's Information and Technology Advisor Sajeeb Wazed Joy wrote on his Facebook page, "The last moments of the launch are fully controlled by the computer. As if there is a bit too much available, the computer does not stop from launching. '
Junk said, "Since there is no risk of such a matter, it is very common to wait for the moment of the launch, because there is nothing to be worried about, because the space-seeker will try to launch this satellite-carrying rocket on Friday after testing everything. '
The directive to all the district and upazila administration of the country for the night to show the countrymen on the big screen from the direct broadcasting system, the rare moment of satellite launch was kept last night. Meherpur district commissioner Parimal Singh said this evening that similar arrangements will be held on Thursday at the community center of Meherpur municipality and the Upazila Parishad office along with the Deputy Commissioner. In addition, the union information centers have also been asked to take this action.
Besides, the Bangladesh Telecommunication Regulatory Commission (BTRC) chairman said yesterday. Shahjahan Mahmud told the media in Florida that there is no problem with rockets and satellites. But there may be problem in the ground system (launch pad).
An official of Bangladesh Communications Satellite Company Limited told Kaler Kantha yesterday that 30 points were examined before launching the rocket. The final decision of launching the green signal on every point in the test through the computer is only possible. But if there is no green signal at any point, then the overall issue goes back to the re-examination. This can be due to a very small error.
Principal Investigator of Nano Satellite 'BRAC-Anbesa' and Associate Professor of BRAC University, launched earlier this year. Md. Khalilur Rahman told Kaler Kantho at 8:15 pm yesterday about the delay in the launch of Bangabandhu-1, "There can be a problem with technical issues at any time. There is nothing to be concerned about. I suppose, tonight our waiting will end. "He told that the date for launch of their Nano satellite 'BRAC-Anbha' was scheduled on June 2 last year. After it was launched on June 4th.
Waiting for: Waiting for the country's own satellite launch is almost a year. Last year in April, it was suggested that 'Bangabandhu-1' is going to be launched in space before December 16 of that year. State Minister for the post and telecommunication department on April 17, Tarana Halim told reporters after the transfer of Bangabandhu-1 satellite to the Prime Minister, "We will send a proposal to the Prime Minister mentioning possible four dates before December 16. Bangabandhu-1 will be launched in satellite space on the date he decides. '
Then in March, Bangabandhu satellite project director Engineer Mohammad Mejbahuzzaman said that the satellite from France could be taken at Cape Cavaler in Florida at any time. Then there are some experiments. US Space Research Organization Nassau also needs approval. Then the satellite will be set to be sent to space.
Later on April 3 at a press conference in New York, BTRC chairman said. Shahjahan Mahmud said it will launch in the first or second week of April.
Meanwhile, for the 26-member delegation to send Florida to the United States from the country on the assumption that its possible date may be determined in the first week of April, two government orders were issued on 26 February and 5 March. The order is approved for four days except during the last week of March or the first week of April.
On March 29, Bangabandhu-1 satellite was taken to the United States on a cargo plane from Antonov Nice Airport in France. At the time, the company's construction company, France's Thales Alenya Space, was informed that the satellite could launch in space on April 24th.
Next, the 'SpaceX' satellite reports the possible launch date of 30 April. The date was changed to 4 May; But it did not work well. In a roundtable discussion on 'Bangabandhu Satellite: Possibilities of Space' on April 25, Postal, Telecommunication and Information Technology Minister Mustafa Jabbar said that Bangabandhu-1 will be launching in satellite space between 1 May and 3 May. A few days later, he said that it will be launched on May 7, 10th.
10 years of effort: BTRC constitutes a committee in April 2008 about the country's first communication and broadcast satellite. This committee was reconstituted in 2010. Then in three years, the Expression of Interest (EOI) was called in 2010 to appoint international consulting organizations to provide technical support to Bangladesh's own satellite launch program. In response, 31 companies from different countries responded. Of the seven companies, five companies have submitted their technical and financial proposals. After following the 'Government Purchase Policy (PPR) 2008', the US-based company, Space Partnership International (SPI), is considered to be the appropriate institution after evaluating the technical and financial proposals of those five organizations. SPI's work is to monitor satellite or satellite launch, market planning, wave coordination with ITU, Satellite Service Design, Satellite Architectural Design, System Design, Tender Preparation, Manufacturing and Well-Launched Monitoring In addition to providing necessary training to build manpower. On March 29, 2012, the company's managing director Bruce Croslowski said with the signing of the BTRC contract signing with them that after the launch of this satellite, Bangladesh will earn around $ 50 million per year.
Meanwhile, many of BTRC officials believe that Bangladesh did not get its own orbital location and necessary frequency from ITU. In addition, the process is also very complex. That is why Russia has to rent orbital positions. The matter was detailed in the 147th meeting of the BTRC held on January 29, 2013.
It is reported in the meeting that the issue of complex and long-term process of getting its own orbital location and frequency required from the ITU. For this reason, BTRC's US-based consultancy company Space Partnership International (SPI) advised to rent or buy orbit positions from anywhere else to ensure satellite launch.
According to the SPI, Russia's Interpatientnik company has expressed interest in selling orbital location owned by 119-degree East longitude. After Interpatientik Bangladesh, through SPI, it was commended that a large United States-based satellite operator expressed interest in renting or purchasing those orbital positions. Then, for the launch of this satellite, Bangladesh has bought an orbital slot for 15 years from Interpatnik, 119.11 degrees East longitude. For this, the cost is 218 crore 96 lakh taka. On November 11, 2015, signing of the contract with the Thales Alenia Space of BTRC to begin the main work on the Bangabandhu-1 satellite. The BTRC was informed in the signing ceremony that the builders of the French company, arranged for satellite structures, launchers, land and space control systems, and two levels of land management and credit arrangements.
According to BTRC sources, the application of Bangladesh's own orbital position in the International Telecommunication Union (ITU) was filed in 2007 to get 69 degrees and 102 degrees east longitude. But the United States, India, Pakistan, Israel, Japan,j Cyprus, Armenia and Uzbekistan objected. This kind of objection is not abnormal due to procedural reasons. The donor is still running. But in the uncertainty quickly, it was quickly negotiated with Interpatnik.
