REPORT ON FUTURE SATELLITE SYSTEMSFuture Polar-orbiting Meteorological Satellite Systems40. The status of the EUMETSAT Polar System (EPS) was presented. The launch period of the first Metop satellite, Metop-1, has been set for November to December 2005. With an expected 45-month lifetime of NOAA-M, launched in June 2002, and a launch of the first Metop satellite in 2005, there should be no (or little) gap in the morning orbit service. 41. All major contracts for the Space Segment, the Launcher and the Ground Segment are signed and respective developments are well underway. The Launch and Early Orbit Phase (LEOP) service contract was kicked off in December 2002. 42. The second part of the EPS System Critical Design Review (CDR-2) was concluded in March 2004. It was declared successful with no major remaining design or interface issues but with, however, a challenging schedule. Good progress was achieved in the planning and definition of the Integration, Verification and Validation (IV&V) activities. All Calibration and Validation plans could be released except the GRAS Validation Plan that is planned to be released in the summer of 2004. The first Satellite System Validation Tests (SSVT) was held successfully in December 2003. It involved the Metop Satellite Service module and the Monitoring and Control System and allowed the verification of the data flows between them. The first Metop satellite to be launched will be Metop-2. Metop-1 will go into storage. EUMETSAT reminded CGMS that the first Metop satellite was an ESA development programme. 43. ESA took this opportunity to inform CGMS of the joint ESA/EUMETSAT Research Announcement of Opportunity on Data for Metop, Envisat and ERS, which is under preparation and will become available at the end of May 2004. 44. China informed CGMS on the development of the FY-3 series of satellites. FY-3 is a new series of polar orbiting meteorological satellites of China. There are seven satellites starting with FY-3A and end with FY-3G to cover the period of 2006-2020. This paper describes the mission and the instruments of FY-3. Compared with FY-1 series, new instruments to be added include the Medium Resolution Spectral Imager (MERSI), the Microwave Radiation Imager (MWRI). Sounding instruments include the Infrared Atmospheric Sounder (IRAS), the Microwave Temperature Sounder (MWTS), and Microwave Humidity Sounder (MWHS). Also, there will be a Total Ozone Unit and Solar Backscatter Ultraviolet Sounder (TOU/SBUS). According to the plan, FY-3A is to be launched in 2006. CMA provided information on the transmission characteristics of the FY-3A satellite. It will broadcast AHRPT, Medium Resolution picture transmission (MPT) and Delayed Picture Transmission (DPT). 45. Rosaviakosmos informed CGMS on the future polar-orbiting meteorological satellite series, Meteor-3M. In 2002 the original Meteor-3M satellite design was revised considerably. It is planned to develop two Meteor-3M satellites on the basis of a “Resurs”-type of unified heavy platform. The satellites will operate in a sun-synchronised orbit and provide operational hydro-meteorological and helio-geophysical information on the atmosphere, Earth surface and the oceans. The working paper includes information on the Low Resolution Multi-Spectral Scanner (MSU-MR), the Onboard Radar Complex (OBRC), Multi-channel Spectral Imaging System (KMSS) with medium resolution, atmosphere temperature and humidity sounding module (MTVZA), Fourier-spectrometer, Helio and geophysical observation facilities. 46. The next satellite in this series, Meteor-3M N2, is planned for launch in 2005. It will provide LRPT and AHRPT direct broadcast data. Meteor-3M N3 is planned to be launched in 2008. 47. NOAA discussed NOAA’s future polar-orbiting meteorological satellite systems. NOAA mentioned once again that NOAA-N will be called up for launch as soon as possible. With regard to NOAA-N’, which had suffered major damage in a mishap on 6 September 2003 when it fell during test, plans on how to overcome the effects of this mishap are being finalized. 48. Information was provided on the international polar-orbiting satellite programme coordination between EUMETSAT and NOAA. The goal of this cooperation is to provide continuity of measurements from polar orbits, cost sharing, and improved forecast and monitoring capabilities through the introduction of new technologies. An agreement is in place between NOAA and EUMETSAT on the Initial Joint Polar-orbiting Operational Satellite System (IJPS). This programme will include two series of independent but fully coordinated NOAA and EUMETSAT satellites, exchange of instruments and global data, cooperation in algorithm development, and plans for real-time direct broadcast. In June 2003 EUMETSAT and NOAA signed the Joint Transition Activities (JTA) Agreement, which extends the cooperation to the Metop-3 satellite and the NPOESS timeframe. 49. NOAA also presents the development and implementation plans for NPOESS. Beginning later this decade, the NPOESS spacecraft will be launched into three orbital planes to provide significantly improved operational capabilities and benefits to satisfy the critical civil and national security requirements for space-based, remotely sensed environmental data. The advanced technology visible, infrared, and microwave imagers and sounders that are being developed for NPOESS will deliver higher spatial and temporal resolution atmospheric, oceanic, terrestrial, and solar-geophysical data enabling more accurate short-term weather forecasts, as well as serving the data continuity requirements for improved global climate change assessment and prediction. The NPOESS programme is well along the path to creating a high performance, polar-orbiting satellite system that will be more responsive to user requirements, deliver more capability, and provide sustained, space-based measurements as a cornerstone of an Integrated Global Observing System. These activities represent a sound beginning for achieving the planned national and international operational satellite programmes that will ensure continuous support to a variety of users well into the 21st century. It was also mentioned that the NPOESS Preparatory Project (NPP) is planned to be launched in late 2006. The earliest possible launch date for NPOESS is 2009 for the mid-morning orbit satellite and in June 2011 for the afternoon orbit satellite. It is planned to continue with NPOESS-C3 in 2013, NPOESS-C4 in 2015, NPOESS-C5 in 2018 and NPOESS-C6 in 2019. Table 4: Future Polar-Orbiting Satellites Coordinated Within CGMS (as of 20 May 2004)
