Abstract
Tien Shan High-Altitude Scientific Station is located at an altitude of 3340 m above sea level ata distance of 30 km from the city of Almaty. The station conducted a wide range of researchprojects. One of them is the “Hadron-55” complex with the help of which various effects andphenomena associated with the EAS passing through the Earth’s atmosphere are studied. Theinstallation includes a network of neutron monitor, ionization calorimeters, a system ofscintillation detectors. In addition, the station contains such complexes as ALMAREC, whichstudies radio signals from EAS and an acoustic recording system that allows recording possibleacoustic effects when muons pass through the earth's crust. Scientific station "Space Station" isone of the best in the CIS
