![Satellite in Bangladesh:
The Bangabandhu-1 (BD-1), will be the first Bangladeshi geostationary
communications satellite operated by Bangladesh Telecommunication Regulatory
Commission (BTRC) which is scheduled to launch in 2017.
It is expected to be located at 119° East longitude geostationary slot. It is named
after the father of the nation Bangabandhu Sheikh Mujibur Rahman.
It will be built by Thales Alenia Space. The total cost of the satellite is 248 million
US dollars (Tk 19.51 billion). Bangabandhu-1 carries a total of 40 Ku and C-band
transponders with a capacity of 1600 megahertz and a predicted life span of 15
years.
Bangabandhu-1 is scheduled to be launched in December 2017 on a Falcon 9
rocket.[1]

The first artificial Earth satellite was Sputnik 1. Put into orbit by the Soviet Union on October 4, 1957 The first artificial satellite used solely to further advances in global communications was a balloon named Echo 1. Echo 1 was the world's first artificial communications satellite capable of relaying signals to other points on Earth. Sputnik 1

The signals from a central station that generates programming to smaller stations that send the signals locally via the cables or the airwaves. The news broadcasts are sent from the field to the studio via the satellite. The satellites provide in the flight phone communications on the airplanes . They are the main conduit of voice communication for the rural areas and the areas where the phone lines are damaged after a disaster. 12

- 18. The future ofsatellite communication ■ Future communication satellites will have more onboard processing capabilities, more power, and larger-aperture antennas that will enable satellites to handle more bandwidth. ■ Further improvements in satellites’ propulsion and power systems will increase their service life to 20–30 years from the current 10–15 years. ■ With increasing video, voice, and data traffic requiring larger amounts of bandwidth, there is no dearth of emerging applications that will drive demand for the satellite services in the years to come. . 18
- 19. The future ofsatellite communication ■ The communications satellites have the ability to rapidly communicate between a number of widely dispersed locations. ■ big manufacturing companies and the department stores to perform inventory management , like as banking services to even small towns. ■ GPS locators are increasingly included in the car direction services . GPS based systems are used by the civilians and the military for navigation on land , the sea , and the air. 19
- 20. Conclusion: Satellite Communication isvery important for our modern world. In one word we cant imagine one second with out it. In every sphere of life we use it, and the future use of satellite is more glorious.
