Zurich, 7 November 2018. The first structure of the second generation of European meteorological satellites (MetOp-SG) was delivered to Airbus Defence and Space in Toulouse at the end of October. This structure will undergo a comprehensive set of qualification testing performed at system level on the satellite Structural and Thermal Model (STM) by Airbus Defence and Space before being returned to RUAG Space for refurbishment to the satellite A flight model. The series of tests are required to validate the satellite performance, paving the way for the manufacture of the remaining flight models.
Developed and manufactured by RUAG Space, the six meter high structure consists of more than 50 parts, including a composite cone and cylinder together with a number of carbon fibre and aluminium sandwich panels. Together with the tertiary brackets, the overall structure weighs approximately 1000 kg. The STM structure, together with the further five structure flight models to be delivered over the next years, will serve as the “backbone” of the MetOp-SG satellites.
Six more satellites as follow-on to the MetOp first generation
The first generation of MetOp satellites provide observation data used for weather and climate forecasts. MetOp-SG aims to continue and to enhance these critical observations from the same Low Earth Orbit. The MetOp satellites operate in a sun-synchronous, polar orbit at an altitude of around 800 km above Earth, which is much closer than the 36,000 km distance of geostationary satellites and enables them to deliver much more precise meteorological measurements of the Earth’s atmosphere and surface.
The MetOp-SG satellites feature several types of instruments: optical (visible and infra-red) and micro-wave imagers and sounders, and a radar scatterometer. The payload is so large that it is split across two series of satellites (called satellite A and satellite B) with three satellites in each series – i.e. six satellites in total. The launches are envisaged in 2022, 2029 & 2036 for satellites A1 – A3 and 2023, 2030 & 2037 for satellites B1 – B3. “We are proud to continue our involvement in the MetOp programme”, says Peter Guggenbach, CEO RUAG Space. “We will manufacture the satellite structures for all six satellites, having already supplied structures for the three satellites of the original MetOp first generation programme.”
The last satellite of the first generation, called MetOp-C, was launched yesterday from Kourou Spaceport in French Guyana.
MetOp-SG is a collaborative programme between ESA and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), with ESA responsible for the development of the satellites and associated instruments. ESA selected Airbus Defence and Space as the prime contractor.
