Are SENC

though they’re on
the DVD?
Why do some
ECDIS use
IHO.PUB instead
of IHO.CRT?
Do the CDs
included the
IHO.CRT and
IHO.PUB?
Is there still a
need for the AIO
disc when using
the DVD?
Are there any
plans for a special
download tool, for
end users with
slower
broadband?
What size DVD is
used?
Yes they are. SENC service providers deliver ENCs in proprietary ECDIS
Manufacturer formats instead of S-63. However some ENC producer
nations do not allow their ENCs to be included in SENC services and
these ENCs have to be supplied using S-63. Therefore the format that the
S-63 ENCs are delivered in will need to be upgraded to S-63 Edition 1.1 by
the end of 2013.
New ENC base cells are released every week, as they become available.
These will be made available immediately on both the DVD and CD. The
current process of re-issuing the Base CDs every 8 weeks will not be
required for the DVD.
The IHO Public Key, which is used to authenticate the ENCs delivered in
S-63 1.1, is available in 2 equally valid forms:
> As an X509 digital certificate, called IHO.CRT
> As an ASCII text file, called IHO.PUB
Most ECDIS use the certificate file, IHO.CRT. However some ECDIS use
the text file, IHO.PUB, instead. Both allow S-63 Edition 1.1 to be
authenticated by the ECDIS.
Both files are available in the root folder of all AVCS S-63 1.1 media (CD
and DVD). The user simply needs to load the type of file that is requested
by the ECDIS.
Yes, the IHO.CRT and IHO.PUB files will be included in the root folder of
the AVCS DVD and 1.1 CDs until the transition is complete.
Yes, AIO will continue on a separate disc for technical reasons related to
exchange sets.
Disc images will continue to be on the FTP site which provides more
robust downloads. End users are expected to download smaller exchange
set related to their specific areas using e-Navigator Planning Station or the
AVCS Online Updating Service.
We are using the standard 4.7Gb DVD size.
