Elektro-L 1 (also referred to as GOMS 2 “Geostationary Operational Meteorological Satellite”) is the first example of the weather satellite constellation Elektro from the Russian space agency Roskosmos . Together with the other new satellites of the Elektro-L type and the Meteor-M , which was launched in 2009, it is responsible for weather monitoring for Russia.
begin
Elektro-L 1 was successfully put into geostationary orbit from Baikonur on the maiden flight of the Zenit-3SLBF (also known as Zenit-2SB or Zenit-3F) on January 20, 2011 at 12:29 UTC from Baikonur . The new Fregat-SB upper stage, used for the first time at the Zenit, was separated from the target orbit at 21:28 UTC. The start should have taken place on December 25, 2010, but was postponed in connection with an additional check of the documentation of the new Fregat self-service booster. After unfolding the solar cell boom and successfully testing the systems on board, the satellite was declared operational.
function
Elektro-L will provide weather data in the visible and infrared range for 10 years, with a special focus on the storm systems in Asia , the Middle East and the Indian Ocean . The life expectancy for the satellite is given as 10 years. The cameras deliver an image every 30 minutes with a resolution of 1 km per pixel in the visible range and 4 km per pixel in the infrared range.
Together with the Meteor-M, which was launched in 2009, the electric satellites are responsible for weather monitoring for Russia. From their position in geostationary orbit they can constantly observe a large part of the earth. However, since the satellites of the Meteor-M series move in a polar orbit at an altitude of 830 km, they can only cover an area with greater accuracy when they fly over them.
Orbit
On July 13, 2016, a few months after the launch of the second Elektro-L satellite , Elektro-L 1 began maneuvering from its original long-term position over the Indian Ocean at 76 degrees east longitude to a new orbit position in geostationary orbit over the Atlantic at 14.5 degrees west longitude. On October 3, 2016, Mission Control in Korolev announced that the spaceship was approaching its new orbit position and the transfer was complete.
