by recording frequency assignments and, as appropriate, orbital positions used or intended to
be used in the

COORDINATION means
Obligatory NEGOTIATION between Administrations
to
arrive at ” interference-free” operation
by
following the processes and Procedures described in Radio Regulations
Radio Regulations-a binding international treaty(No. 31 of the ITU Constitution)
We shall focus upon the: Coordination Approach
dhh
Coordination is central to the three stage process :
Advance Publication of Information
(API)
Coordination
Notification & Recording in the Master International
Frequency Register(MIFR)
Submission of advance informationthat is published by the BR
Exam. by BR to establish Findings, coordination Requirements and to publish . Coordination is then carried out by the responsible administration.
Examination of the Notification, checking of Coordordination Agreements & Recording in MIFR
Advance Publication of Information
(API)
Coordination
Notification & Recording in the Master International

Let us now focus on the process of coordination to establish Findings
and coordination Requirements
Coordination Examination comprises of two parts:
No. 9.35 (11.31)
Compliance with Table of Frequency Allocation
No. 9.36:
Identify any administration with which coordination may need to be effected
No. 9.35 (11.31)Compliance with Table of Frequency Allocation
refers to:
Conformity with
the `Table of Frequency Allocations’
(Article 5)Successful application
of No.9.21(when reqd.)
Conformity with
other procedures i.e. Rules of Procedure(RoP)
