At present, effective reaching of the goals of meteorology is impossible without use of data supplied by Earth remote sensing satellites. One of such valuable assets is a network of satellites positioned at the Geostationary orbit. The World's Meteorological Organization superwises international network of GEO weather sensing satellites, which is formed by American GOES constellation satellites, European Meteosat, Russian GOMS №1/Elektro №1 (non-functional since 1998), and Japanese GMS. Also, there are Indian Insat and Metsat, and Chinese FY-2 weather sensing satellites at GEO.



The new Russian weather satellite Electro-L, built in 2010, has iternational designation GOMS №2 (Geostationary Operational Meteorological Satellite). It is intended to supply Russian Hydrometeorology and Environmental Monitoring agency with following kinds of information:

  • Weather analysis and forecasting on global and regional scale.
  • Analysis and forecasting of conditions at seas and oceans.
  • Assessing and forecasting weather conditions affecting air traffic.
  • Probing and forecasting ionospheric conditions in the near space and Earth's magnetic field.
  • Monitoring of climate and global changes in environment.
  • Assessing conditions and developments at disaster sites.
  • Monitoring activities harmful to natural environment.

Elektro-L should be able to image multispectrally the entire visible hemisphere of Earth with resolution of 1 km per pixel (visible light band) and 4 km (IR band), every 30 minutes. In emergency cases, like during natural disaster's development observations, frequency of imaging may be increased to once in every 10-15 minutes, at command from the ground.

In addition to that, Elektro-L will obtain space environment data, relay and exchange meteorological data between autonomous weather platforms and other satellites, and also receive distress signals from SARSAT beacons.

Spacecraft Overview

Elektro-L is a second generation geostationary weather monitoring spacecraft, built and operated by Russia.

The spacecraft is designed to have modular composition. It consists of Service Systems Module and Payload Module. The former is represented by Navigator universal bus, which is developed by Lavochkin Space for use as a core in various spacecraft, such as Spektr series orbiting observatories.

Mass of the spacecraft in operational mode is about 1500 kg. Its effective lifetime should be no shorter than 10 years.

Electro-L is designed as an elevated operational compatibility spacecraft. When assembling and electric tests of the spacecraft are done at Lavochkin Centre, the satellite is delivered to a cosmodrome virtually ready to fly. This technology allows for significant cost savings on launch preparatory works.

2nd stage burnout, the upper composite separated. It should be in the parking orbit now.

Now coasting for approx 1 orbit before the 1st Fregat burn at 16:44:26 MSK (13:44:26 UTC).

We have a confirmation of on target delivery of the spacecraft, spacecraft separation, solar array deploying! All spacecraft systems are working beatiful accordint to the first tests! :thumbup:

Electro-L Reaches Targeted Orbit

:: 21.01.2011

Launched by Zenith-SB rocket from Baikonur yesterday, Russian weather satellite Electro-L has successfully separated from Fregat-SB upper stage and reached the targeted orbit at 00.28 MSK, Jan. 21.
With this launch, Russia will have its own weather satellite in GSO. Within 10 years of orbital operations, Electro-L will provide Russian and world customers with weather prediction, sea and ocean status, ionosphere status, climate monitoring, ecological data.

Bravo Zenit, Bravo Fregat, Bravo Elektro-L, Bravo Yuzhnoye/Yuzhmash, Bravo Lavochkin, Bravo Russia, Bravo Ukraine! :cheers: :woohoo:



Translation for the above:

There's no point for us to quarrel -
Let's sit down and hit the barrel!
:lol:
