SFCG activities status

• The SFCG-26 Meeting took place in Bonn (Germany)
  in September 2006. The meeting was attended by 59
  delegates from 13 Space Agencies and 2 Observer
  Agencies.
• SFCG finalized the document SFCG WRC-07
  Objectives, where the SFCG position is indicated
  for each WRC-07 Agenda Item. The document is
  provided in annex.
• SFCG appreciated the willingness expressed by
  CEOS at their 19th Plenary in London to actively
  cooperate with SFCG. An informal preliminary
  version of the BNSC survey results was circulated
  for information only. The final version is
  expected at CEOS 20th Plenary.
• SFCG-27 will take place in September 2007 in
  Spain.

The path to WRC-07

• The position of the various national
  administrations and regional groups (CEPT, CITEL,
  APT) on the various WRC-07 Agenda Items will be
  finalized in the next months.
• The Conference Preparatory Meeting (CPM) will
  take place in February 2007.
• It will finalize the report on the results of the
  technical studies related to WRC-07.
• The WRC-07 Conference will take place from
  mid-October to mid-November 2007.

SFCG WRC-07 Objectives

• The main WRC-07 Agenda Items of concern for EO
  are
• 1.20. Regulatory measures to limit unwanted
  emissions in bands used by EO passive sensors
  (1.4, 24, 31 and 50 GHz). Essential for the
  future of atmospheric RF vertical sounding (last
  3 bands). Important for future salinity/soil
  moisture measurements by radiometers (1.4 GHz).
  Only explicit regulatory limits will protect
  these bands. Generic Recommendations will not
  really help.
• 1.2 Identify sharing criteria in the bands 10.6
  and 36 GHz. These bands are used by EO passive
  sensors (radiometers). The agreement on sharing
  criteria with terrestrial fixed and mobile links
  appears to be difficult in the 10.6 GHz band.
  Agenda Item 1.2 includes also the extension from
  200 to 300 MHz of the allocation to
  Meteorological satellites downlinks around 18
  GHz. This will be necessary to cover the high
  rate downlink requirements of future
  geostationary Meteorological satellites.

SFCG WRC-07 Objectives (cont.)

• 1.3 Extension of the 9 GHz active sensors
  allocation from 300 MHz to 500 MHz. Required for
  high-resolution SAR imaging (1 meter)
• 1.12 Modifications of the ITU filing regulations
  to allow a proper registration of the satellite
  active and passive RF sensors. Currently the
  mechanisms are suitable to register satellite
  data communication links only.

Other SFCG subjects of interest for CEOS

• A new Recommendation has been finalized in ITU.
  It establishes new rules on the use of the
  8025-8400 MHz for EO data downlink. It is based
  on a similar SFCG Recommendation that was
  finalized at SFCG-25 and then brought to ITU. The
  objective is to introduce some discipline in the
  use of the band in order to mitigate the effects
  of the expected overcrowding of this band in the
  next years.
• Studies are on-going in SFCG about how to best
  share between EO and space science missions the
  25.5-27 GHz band for very high-rate downlink.
  Future lunar exploration missions, Lagrangian
  points missions and large EO missions are likely
  to use this band in the future.
• In addition to the famous car radars at 24 GHz,
  many new Short Range Devices (SRD) are proposed
  at many frequencies. Continuous surveillance of
  these proposals is needed by everybody. SRDs are
  typically unlicensed devices, i.e. their number
  and location is not controllable by anybody, once
  they are authorized by a telecom authority.

Cooperation between CEOS and SFCG Status of
actions

• Lobbying actions from SFCG members on WRC-07
  issues are producing some results with some
  administrations. Results to be finalized in the
  next months leading to CPM. Any feedbacks on
  lobbying actions by CEOS?
• Providing ammunitions 1)ESA study on GMES
  socio-economical value. 2)GEO task AR-06-11 any
  output yet? 3) Others?
• Identifying the long-term needs BNSC Survey.
  Subject of a separate presentation

Next steps

• Increased lobbying activity needed at all
  levels. Now is the moment national
  administrations and regional groups are
  finalizing their positions for WRC-07. Some
  administrations currently have official or
  unofficial preliminary positions not in line with
  our objectives. There is where our lobbying
  action should concentrate.
• This lobbying action by CEOS and SFCG members can
  be helped by the WRC-07 Objectives document, but
  what is also required is an increased awareness
  by the regulators of the importance of the EO
  services and the impact on them of RF
  interference. Talking directly to people is
  essential!
• Will CEOS produce further outputs in the areas
  identifying the long-term needs and providing
  ammunitions?
