INTRODUCTION
Article 6 of the Constitution provides that
all administrations are bound to abide by the
provisions of Constitution/Convention and the
Radio Regulation when the radiocommunication
stations operated by it are capable of causing
harmful interference to radio services of other
countries.
5
International Rights and Obligations
No.8.1 The international rights and obligations
of administrations in respect of their own and
other administrations frequency assignments
shall be derived from the recording of those
assignments in the Master International Frequency
Register (MIFR) Such rights shall be
conditioned by the provisions of these
Regulations and those of any relevant frequency
allotment or assignment.

Procedure for Effecting Coordination
Article 9 Section II-Procedure for effecting
coordination No.9.6 Before an administration
notifies to the Bureau or brings into use a
frequency assignments in any of the cases listed
in No.9.7 to 9.21 it shall effect coordination,
as required, with other administrations
identified under No.9.27. Administrations may
seek the assistance of the Bureau under the
provisions of Articles 7,
Article 9 and Article 13 in applying the
coordination or notification procedures of
Article 9 and Article 11

Coordination Area of Mobile Earth Stations
For a mobile earth station, the periphery of the
service area is extended by the coordination
distance. The coordination distance may be a
predetermined coordination distance or it may be
calculated (No additional protection can be
assumed to be available from the earth station
horizon elevation angle for all azimuths)

Response to Request of Coordination by
Administration B

• Acknowledge receipt of the coordination request
• Collect data on existing and planned TS ES(ODT)
  to be brought into use in the next 3 years or to
  be operated prior to the date of bringing into
  use of earth station, falling within its
  coordination area.

B
A
52
Response to Request of Coordination by
Administration B

• Conduct Technical Examination
• Detailed technical examination is not required
  if the TS ES(ODT)
• Are not inside the coordination area or
• Has no frequency overlap or
• With lesser potential are not inside the
  Auxiliary contours
• Interference is within the acceptable level

53
Response to Request of Coordination by
Administration B
Conduct Detailed Technical Examination
Detailed technical examination is required if TS
ES(ODT) inside the coordination contour or
auxiliary contours could cause or receive
unacceptable interference. Exchange of
information like terrain profile, modulation
scheme, precise e.i.r.p and sensitivity may help
administrations to reach coordination agreement
54
Response to Request of Coordination by
Administration B
Coordination agreement is reached (9.52B)
Administration B may agree to the coordination
by requesting the inclusion of its TS ES(ODT)
not yet recorded in the MIFR but are to be
brought into use in the next three years and
sends complete characteristics (AP4 Annex 1A/1B
or 2A/2B) of these stations to Administration A
and the Bureau.
55
Response to Request of Coordination by
Administration B

• Coordination agreement is not reached (9.52)
• Administration B does not agree to the
  coordination request. It shall
• within four months of the date of dispatch of the
  coordination data, inform Administration A of its
  disagreement
• provide information concerning its own
  assignments upon which that disagreement is
  based and
• make such suggestions as it is able to offer with
  a view to satisfactory resolution of the matter.
• A copy of that information shall be sent to the
  Bureau.
• Only that information relating to existing
  radiocommunication stations or to those to be
  brought into use within the next three months for
  terrestrial stations, or three years for earth
  stations, shall be treated as notifications under
  Nos. 11.2 or 11.9.
