Llano de Chajnantor Observatory is the name for a group of astronomical observatories located at an altitude of over 4,800 m (15,700 ft) in the Atacama Desert of northern Chile. The site is in the Antofagasta Region approximately 50 kilometres (31 mi) east of the town of San Pedro de Atacama .
These include the Chacaltaya Astrophysical Observatory in Bolivia, which at 5,230 m (17,160 ft) was the world's highest permanent astronomical observatory [9] from the time of its construction during the 1940s until surpassed in 2009 by the new University of Tokyo Atacama Observatory, [10] an optical-infrared telescope on a remote 5,640 m ...
The array has been constructed on the 5,000 m (16,000 ft) elevation Chajnantor plateau – near the Llano de Chajnantor Observatory and the Atacama Pathfinder Experiment. This location was chosen for its high elevation and low humidity, factors which are crucial to reduce noise and decrease signal attenuation due to Earth's atmosphere. [1]

The Atacama Pathfinder Experiment (APEX) is a radio telescope 5,064 meters above sea level, at the Llano de Chajnantor Observatory in the Atacama Desert in northern Chile, 50 km east of San Pedro de Atacama built and operated by three European research institutes.
The Llano de Chajnantor is a 5,100-metre-high (16,700 ft) plateau in the Atacama Desert, about 50 kilometres (31 mi) east of San Pedro de Atacama. The site is 750 metres (2,460 ft) higher than the Mauna Kea Observatory and 2,400 metres (7,900 ft) higher than the Very Large Telescope on Cerro Paranal.
The Cosmic Background Imager (or CBI) was a 13-element interferometer perched at an elevation of 5,080 metres (16,700 feet) at Llano de Chajnantor Observatory in the Chilean Andes. It started operations in 1999 to study the cosmic microwave background radiation and ran until 2008.
