With an array of sophisticated instrumentation, MetOp-A jointly established by ESA and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) promises to provide data of unprecedented accuracy and resolution on a host of different variables such as temperature and humidity, wind speed and direction, ozone and other trace gases.
Since the arrival of the MetOp-A satellite at its launch site in Baikonur on 18 April 2006, the Service Module, Payload Module and Solar Array, which were shipped as individual items, have been integrated and tested.
Following a review of the satellite status and results of the testing to date, together with the outputs of EUMETSAT's review of the readiness of the ground segment, launcher and overall system, EUMETSAT and ESA authorised EADS Astrium on 17 June to commence the MetOp-A satellite fuelling activities, marking a milestone in the EUMETSAT Polar System (EPS) programme.
Following the completion of the MetOp-A fuelling, the satellite will be integrated with the so-called Fregat upper stage before being encapsulated in the fairing. The resulting upper composite will then be integrated with the Soyuz launcher and the complete system will be rolled out to the launch pad three days prior to the launch.
The MetOp programme, which consists of three satellites to be flown sequentially to ensure the delivery of continuous data until at least 2020, forms the space segment of the EPS programme and represents the European contribution to a new cooperative venture with the American National Oceanic and Atmospheric Administration (NOAA).
