Preparation of WRC-2003

• Consolidation of the regulatory provisions for
  non-GSO satellite systems

2
Background

• Following European proposals, WRC-97 established
  power limits on non-geostationary satellite FSS
  systems in 7 GHz of spectrum
• To provide clear protection to geostationary
  satellite systems
• To provide a clear regulatory framework for
  non-GSO systems by quantifying No. S22.2
• WRC-2000 reviewed the levels of these limits,
  confirmed the approach taken, with
• Validation limits (to be met on each point of the
  Earth, for any direction towards the GSO,
  verified by the ITU )
• Operational limits (to be met into any
  operational GSO earth station antenna, not
  verified by the ITU, but committed to by the
  non-GSO administration)

Agenda Item 1.19

• Avoid misapplication of the regulatory provisions
  by splitting/combining non-GSO systems
• ITU-R studies have shown that this is not a new
  situation, hence, no specific provision is
  required.
• This is supported by Europe

4
Agenda Item 1.29 (1)

• Development of procedures in case the operational
  limits are exceeded (Resolution 78 (WRC-2000))
• ITU-R studies current or updated procedure
  under Article S15 (Procedure in case of harmful
  interference)
• An ITU-R recommendation is being developed for
  this purpose. Europe supports its incorporation
  by reference in the RR (in Article S22)

5
Agenda Item 1.29 (2)

• Achieving balanced sharing arrangements between
  GSO and non-GSO FSS systems at 37.5-50.2 GHz
  (Resolution 136 (WRC-2000)).
• ITU-R studies have not identified any specific
  arrangement, except for the possible use of
  opposite polarisations between GSO and non-GSO
  systems
• European position is to preserve long-term access
  to this spectrum by GSO networks
• No specific European proposal identified at this
  stage

6
Agenda Item 1.37

• Technical and regulatory provisions for satellite
  systems using highly elliptical orbits (HEO)
• Very wide scope, potentially covers all satellite
  services and all bands allocated to them.
• European preliminary position
• HEOs should continue to be considered as having
  the same regulatory standing as other non-GSO
  systems
• All bands that may be used by HEO systems should
  be covered, with particular attention to the
  protection of terrestrial services

7
Agenda Item 1.37 (2)

• Definition in ITU-R not yet clear
• European preliminary position for the various
  bands to be considered, in respect of GSO/non-GSO
  sharing
• MSS below 3 GHz NOC
• BSS below 1 GHz S9.12/12A/13 SUP S22.2
• BSS (sound) between 1 and 3 GHz idem
• BSS (other than sound) and FSS between 1 and 3
  GHz S22.2, quantified
• Above 3.4 GHz focus on bands where S9.11A does
  not apply and no limits are included in Article
  S22, and quantify S22.2.
