2.4.1 Recognized services are subject to oversight
by IMSO according to the rules and arrangements set out in the public
services agreement (PSA) concluded between the service provider and
IMSO. No maritime satellite system should be used in the GMDSS unless
it has first been recognized by the Organization in accordance with
the above procedure and the service provider has signed a PSA with
IMSO.
2.4.2 IMSO should conduct its oversight of the
recognized services on a continuing basis.
2.4.3 Responsibility for ensuring compliance with
the standards established by this annex, other relevant mandatory
international instruments and, to the extent necessary, those recommendations,
resolutions and procedures of IMO and ITU which are of a recommendatory
nature insofar as they relate to the provision of GMDSS services,
rests with IMSO under the terms of the Public Services Agreement.
