We began to hear first of storms and anticyclones when television was in black and white. For 30 years the face of "What's the weather be like tomorrow?" Was that of José Antonio Maldonado. With him also we familiarize ourselves with images of the Meteosat, which today is still news.

The first geostationary satellites Meteosat weather observation was put into orbit by the ESA in 1977. The last of the first generation satellite, Meteosat 7 was launched in 1997 and today, July 15, 2015, is expected to launch the fourth and last of the second generation: the MSG-4. An Ariane 5 ECA will do the honors this morning, between 23:42 and 00:19 hours, from French Guiana. You can follow the launch date as desired from the website of the ESA. This satellite, like its predecessors, and the third generation is already being designed, has an important participation of Spanish engineering.

There are seven domestic companies collaborating in this project, providing systems and equipment to all MSG satellites, with a total stake of 7%, and 12% in total MGS program. Airbus DS, Alter Technology Tuv Nord, Crisa, GMV, Indra, Thales Alenia Space SENER and Spain have developed key to substantially improve the collection and analysis of meteorological data systems.

Spanish role in second-generation satellites MSG
Airbus Defence and Space has been commissioned to work on the thermal protection of the satellite, creating systems of active and passive electronic thermal control units and instrument. It has also created the wiring SEVIRI instrument (Spinning Enhanced Visible and Infrared Imager, or sensor Swivel visible and infrared imagery), capable of capturing up to 12 spectral environments instead of 3.

Alter Technology TÜV Nord has worked on the selection of components, engineering, testing and procurement of electronic components of the satellite.

Crisa (Airbus DS) has worked on Functional Control Unit (FCU) of the main SEVIRI instrument.

GMV has provided services to the AEMET for the generation and maintenance of a software package for data processing of the MSG program, and is responsible for the engineering and system integration, as well as maintenance and support to end users (Satellite Nowcasting Application Facility). It also deals with ongoing with the Meteorological Institute of Portugal for the SAF (Satellite Application Facility) LAND; the Flight Dynamics support the LEOP of MSG from the ESOC control center .; independent verification and validation of Data Handling Software .; and it contributes to the development of the subsystem MPEF (Meteorological Products Extraction Facility) in EUMETSAT

Indra provides supply station BRGS (Backup and Ranging Ground Station) control for satellite fleet and second generation of EUMETSAT owned by INTA. The station is located in Maspalomas, providing services accessible remotely from EUMETSAT headquarters in Darmstadt, Germany. The station performs various services, among which monitoring satellites, and controls sending commands to, and performing the location and precise satellite positioning.

SENER has been responsible for the design, manufacture, verification, testing and delivery of the following equipment of the camera (radiometer) SEVIRI: The calibration unit infrared channels .; the ejection cover cooling system, consisting of a reinforced panel, to prevent ingress of contamination, and mechanisms that serve as anchors launch and in orbit the ejected by pyrotechnic means; the optical screen of the visual field, which protects the field of view SEVIRI any residual beam light that can degrade the quality of the recorded image; and finally the ejection cover said optical screen, also consisting of a reinforced panel which emerges by pyrotechnic means once in orbit. It has also dealt with the design, analysis, verification and testing (with staff integrated into the Alcatel team) of the linear actuator or Drive Unit (DU), whose function is to position the optical guiding the visual field of the SEVIRI radiometer.

Spain Thales Alenia Space has been commissioned to manufacture raw data Modulator RDM, data modulator for transmitting images. And the Image SCOE, a bank simulation image string instrument and real-time monitoring of data transmission.

The MSG-4 is the latest second-generation satellites developed by ESA and EUMETSAT (European Organisation for Meteorological Satellites), and its fundamental mission is to provide meteorological and environmental monitoring around the
