Túpac Katari 1
Túpac Katari 1 or TKSat-1 is a telecommunications satellite that the government of Bolivia outsourced to People's Republic of China (PRC) to serve telecommunications in Bolivia, such as mobile, television and Internet use. It was launched into orbit on 20 December 2013 from the Satellite Launch Center in Xichang, China, with a trial period of a little over three months, and commercial operation starting in March 2014. It was built on behalf of the Bolivian Space Agency. The China Great Wall Industry Corporation (CGWIC), a subsidiary of the China Aerospace Science and Technology Corporation (CASC), was responsible for the construction (using French, German and USA technology), launch and orbit of the satellite. The satellite is named after 18th century Bolivian independence activist Túpac Katari.

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Science And Technology In Bolivia
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek man ...
