Availability and use without interference of a frequency resource for operating the Fengyun satellite system, e.g. the sensors, data transmission, telemetry and command control, and automatic data collection platform service, is the concern of NSMC. The Ministry of Industry and Information Technology (MIIT) is responsible for frequency management and protection in China. NSMC provides the MIIT with necessary technical support in coordinating the Fengyun satellite system with other operational systems. Often, NSMC is represented in the official delegation to relevant international frequency coordination meetings such as ITU, SFCG, as well as CGMS.
Fengyun Satellite Frequency Networks
As of 08 July 2014, CMA is operating four geostationary meteorological satellites and three non-geostationary meteorological satellites, the assignments of FY-2A/FY-2AS (105°E), FY-2B/FY-2BS (86.5°E), FY-2C/FY-2CS (123.5°E) satellite networks have been recorded in the MIFR (Master International Frequency Registration).
FY-2 series satellite networks contain UHF, L, S, and C bands. All the FY-2 satellite fillings are brought into use by Fengyun series geostationary meteorological satellites.
The coordination requests of the FYGEOSAT-79E (79°E), FYGEOSAT-86.5E (86.5°E), FYGEOSAT-99.5E (99.5°E), FYGEOSAT-105E (105°E), FYGEOSAT-112E (112°E), and FYGEOSAT-123.5E (123.5°E), FYGEOSAT-133E (133°E) satellite fillings were submitted to ITU in 2011. FYGEOSAT series satellite networks contain UHF, L, S, X and Ka bands, and the fillings will be used by the current and future Fengyun geostationary satellites according to the satellite launch plan.
Non-geostationary satellites FY-3A, FY-3B and FY-3C, launched on 27/05/2008, 5/11/2010 and 8/10/2013 respectively, are operating at L, S and X bands under FY-1, FY-3 and FY-3-A satellite networks that have been registered to the ITU.
