Metop A

 2006-044A


Astrium-SAS's Metop will make up the Eumetsat Polar System (EPS) [719] and use the Spot bus from MMS-F. Mass 4175 kg launch including 316 kg of hydrazine. Launch 2005. 0930LT SSO planned. Control by Eumetsat via Kiruna. Astrium GmbH (Dornier) makes the payload module. Astrium Ltd. (MMS UK) makes the SM mechanical system.

First satellite is Metop 2, to be named Metop A after launch.

Size is 6.3 x 3.4 x 3.4 at launch, 17.6 span after deployment of the single solar array and the 2 ASCAT antenna booms each around 3m long. Shape is box + panel + 2 antennae.

By 2013 Metop A was operating as the secondary satellite with Metop B in the prime role.


Metop A launch mass breakdown 

METOP A dry 3769  
Hydrazine  316  
Adapter  90? 
Fregat prop  3724? 
Fregat dry  1000?  

Total  8900  

0930LT

17.6 x 6.7 x 5.4m mass. 11.3m span with solar array. Mass 4086 kg (BR-261) full, 3769? kg dry (or 3858 kg?) The 1666-SF adapter was used between METOP and Fregat. An interstage (PKhO) was used between Fregat and the LV.

Launch by Soyuz-2-1A No. 3 (Starsem ST16) with Fregat No. 1011 (88515?) in 2005 with new 11.4m long 4.1m dia fairing. Azimuth 354.6. Blok A and fairing drop near Perm. Blok I drop near Greenland at 81N 5W.

The 14A14 Soyuz-2-1A Fregat (Zh15000-003/1011) rocket with MetOp was transported to the launch platform PU-6.
