The program was established to ensure the operational continuity between the end of the successful Meteosat Operational Programme in 1995 and Meteosat Second Generation (MSG), which came into operation at the start of 2004 using improved satellites. The MTP provides an overlap with MSG by continuing the current Meteosat system until at least the end of the year 2005.
The first generation of Meteosat satellites, Meteosat-1 to Meteosat-7, provide continuous and reliable meteorological observations from space to a large user community. In addition to the provision of images of the Earth and its atmosphere every half-hour in three spectral channels (Visible, Infrared) and Water Vapour, via the Meteosat Visible and Infrared Imager (MVIRI) instrument, a range of processed meteorological products is produced. Meteosat also supports the retransmission of data from data collection platforms in remote locations, at sea and on board aircraft, as well as the dissemination of meteorological information in graphical and text formats.
They are 2.1 metres in diameter and 3.195 metres long. Its initial mass in orbit is 282 kg, and in orbit, the satellite spins at 100 rpm around its main axis
Meteosat Second Generation was designed in response to user requirements to serve the needs of Nowcasting applications and Numerical Weather Prediction. In addition the GERB instrument provides important data for climate monitoring and research.
The new satellites are spin-stabilised like the previous generation, but with many design improvements. The more frequent and comprehensive data collected by MSG also aids the weather forecaster in the swift recognition and prediction of dangerous weather phenomena such as thunderstorms, fog and explosive development of small but intense depressions which can lead to devastating wind storms.
The MSG satellites are 3.2 m in diameter and 2.4 m high and spins anti-clockwise at 100 RPM at an altitude of 36,000 km.
On January 29 2004 the first Meteosat Second Generation satellite MSG-1, renamed to Meteosat-8, commenced routine operations. In addition to the main optical payload SEVIRI (Spinning Enhanced Visible and Infrared Imager), Meteosat-8 also carries the secondary payload GERB (Geostationary Earth Radiation Budget) instrument.
At the end of June 2007 Meteosat-6, -7, -8 and -9 were all operational. Meteosat-6 and -7 are stationed over the Indian Ocean. Meteosat-8, and -9 are both located over Africa with various differences in operational configuration. Meteosat-6 provides a DCP service and is a backup to Meteosat-7, where Meteosat-7 provides the primary imagery coverage over the Indian Ocean (with images every 30-minutes). Meteosat-8 is a backup to Meteosat-9 (and Meteosat-8 also provides an operational European 'rapid scan' mode service, which commenced in the second quarter of 2008 (with images of Europe every 5 minutes)). Meteosat-9 provides the main full earth imagery service over Europe and Africa (with images every 15-minutes).
The launch of MSG-3 is tentatively planned for 2010 and MSG-4 tentatively planned for the first half of 2013. Like MSG-1 and MSG-2, MSG-3 and MSG-4 are planned for launch by Arianespace.
