TKSat-1 (also called Tupac Katari or Túpac Katari 1 ) is a commercial communications satellite of the Agencia Boliviana Espacial (ABE). It is the first Bolivian communications satellite and was named after the revolutionary Tupaq Katari (* 1750; † 1781).
financing
Until now, the state, the media and telecommunications companies had to rent channels for data traffic from foreign providers. Rural residents in particular should benefit from space technology. In remote areas and difficult terrain, many communities have no telephones, radio or television. Article 20 of Bolivia's constitution guarantees the right to communicate. The income from leasing to companies and states flows back into the state coffers.
The Bolivian state financed the satellite, which cost about 302 million US dollars, with the help of a loan of 295 million US dollars from China's development bank. The satellite has been in commercial operation since April 2014. About $ 10 million was earned in 2014, about $ 16 million in the first 12 months, and $ 33 million in the first two years at 60% occupancy. Income of $ 20 million annually is required for the financing.
construction
The three-axis stabilized satellite with 26 Ku-band -, 2 C-band - and 2 Ka-band - transponders fitted to and from position 87.2 ° West from South America provide telecommunications services and television. It was built on the basis of the DFH-4 satellite bus of the Chinese Academy for Space Technology (CAST) and has a planned service life of 15 years. The contract to build and launch the satellite was signed on December 13, 2010 between China Great Wall Industry Corporation (CGWIC) and Agencia Boliviana Espacial.
business
The satellite was launched into geostationary orbit on December 20, 2013 at 16:42 UTC by a Langer Marsch 3B / E launcher from the LC2 launch complex of the Xichang Satellite Launch Center . The ground stations for control by Bolivia's ABE space agency are in El Alto near La Paz and in the village of La Guardia in the lowland department of Santa Cruz . They are operated by Bolivian experts who were trained in China and were handed over on December 28, 2013.
