GSM is the abbreviation of Global System for Mobile Communications and is the most widely used digital wireless telephone technology in the world. It is a standard that describes the 2G cellular network protocol. It uses the base station to generate a stable electromagnetic field radio frequency signal to relay information. When the magnetic field is in the metal, it will produce interference signals. Rubezh can be detected and recorded. The Doppler effect and triangulation are used to determine the precise coordinates of the target by analyzing the signals recorded by the base station. Once Rubezh has captured the identified target, the data is sent to the monitoring center via the GSM network, including the Defense Management Center of the Russian Ministry of Defense and the Russian Space Iraq Air Defense System Command and Control Center.
