The first two of a planned constellation of four spacecraft for the first Russian space weather monitoring system called "Ionozond". The system being created is designed to solve scientific and applied problems in obtaining fundamental knowledge about the Earth's ionosphere and to receive the ability to monitor near-Earth space continuously. Four Ionosfera-M spacecraft located in two orbital planes (two spacecraft in each plane) will be able to transmit information about physical phenomena occurring in the Earth's ionosphere due to active natural and anthropogenic influences. The "Ionozond" space system is being developed by JSC VNIIEM Corporation at the request of the Roscosmos State Corporation, and in the interests of the Russian Academy of Sciences and Roshydromet.
