50th anniversary of the launch of Telstar satellite to space

Half a century ago, on July 12, 1962, the Telstar satellite was launched into space to carry out the function of relaying television signals and the phone had the first satellite TV signal.

During this trip, Telstar successfully carried out transmitting television signals across the Atlantic. This is considered an important milestone in the history of telecommunications technology, marking the information being expanded and exchanged on a global scale.

This event opened a new era for the world telecommunications industry decades before the Internet was born. The first images were transmitted from Andover Earth station in the US state of Maine to the Pleumeur-Bodou Media Center located in the French region of Brittany.

Through satellite Telstar, Americans sent France images of the Statue of Liberty, the speech of President John F. Kennedy and a baseball game, while France transmitted to the United States the image of male singer Yves Montand along with some videos of sports events and the Eiffel Tower.

Telstar was developed based on a multilateral agreement between AT&T (USA), the US Aerospace Agency (NASA), Bell Telephone Laboratories and the French National Communications Company and this is considered part of the space mastery race between the US and the former Soviet Union.

Although it only operated for a few months and could only play video clips in a short time, Telstar opened a future for satellite signal transitions. This is an important premise for a "global village" , which has now become a reality thanks to the Internet and many other types of media.

During her five-year life, Telstar broadcast 400 phone calls, telegraphs, copies of information and television signals. In November 1962, electronic components on Telstar were damaged due to radiation.

Telstar satellite, weighing 77kg, operates in low orbit and can only catch waves in 20 minutes or just above. The base stations are located in the United States and France with a large antenna receiving microwaves to control satellites in a period of nearly half an hour when Telstar passes over each station. Signals from Telstar are received and amplified by microwave wave amplification technology with stimulated emission with low signal noise.

Half a century after the launch of the first satellite on orbit, French Ambassador Francois Delattre reiterated the statement of the late President Kennedy, that the Telstar satellite has explored the technology to help people communicate. , exchange information wherever they are on Earth.
