The geostationary hydrometeorological spacecraft “Electro-L” No. 4, created by the enterprises of the State Corporation “Roscosmos”, after the completion of tests in orbit, began to be used for its intended purpose.
Thus, for the first time in the history of Russian cosmonautics, a grouping of the hydrometeorological space system “Electro” consisting of three satellites is fully deployed in geostationary orbit.
The Electro-L spacecraft No. 2 (launched on December 11, 2015) operates at a standing point of 14.5° west longitude, Electro-L No. 3 (launched on December 24, 2019) — 76° east longitude and Electro-L No. 4 (launched on February 5, 2023) — 165.8° east longitude.
The features of the Electro-L satellites make it possible to conduct a satellite survey of the Earth’s surface from a geostationary orbit with a frequency of up to 15 minutes. Thanks to the round-the-clock transmission from orbit of high-quality multispectral images in the visible and infrared ranges, global issues of climate monitoring are solved, the state of the seas and oceans is analyzed, the efficiency of weather forecasts is increased, emergency information is issued when emergency situations are detected.
The Electro-L spacecraft relay signals from the emergency beacons of the COSPAS-SARSAT international satellite search and rescue system. This helps search and rescue services to respond more effectively to distress signals to save human lives.
The creation of Electro-L satellites is carried out in the interests of Roshydromet within the framework of the Federal Space Program of Russia by the S.A. Lavochkin Scientific and Production Association (part of Roscosmos).
