Warning!
This presentation is subject to modifications and updates along the migration process in Please, be sure that you are always consulting the last, updated version!
Only the date of the first phase of the migration is known. The migration dates for the other phases will be communicated by Inmarsat later on.
Please note that the first migration maybe subject to change as well.
For a better readability and a good understanding of the migration please, use the “slide show” mode of PowerPoint
Thank you!

Our commitment to You!
We would like to assure our customers and partners that a vast and long-term planning process has taken place with regards to the planned I4 Migration process by Inmarsat. A number of considerations, potential issues and technical aspects have been reported in advance to Inmarsat by our Engineers and Inmarsat C experts whilst we work in very close coordination, ultimately the migration process is under the control of Inmarsat. Therefore, despite Marlink’s efforts and specialist support to ensure a smooth a migration a 100% predictable outcome cannot be guaranteed. However, as always, Marlink’s dedicated support team will be available throughout the migration phases to support and help partners and end users and will continue to put professionalism and exceptional customer support at the forefront for our customers and partners!

Migration sequence
The migration will take place in 4 steps
Step 1: Change of coverage for AORW (54W, 3F5) moving to AMER (98W, 4F3).
Step 2: Change of coverage for POR (178E, 3F3) moving to APAC (143.5E, 4F1).
Step 3: Relocation of AORE from 15.5W, 3F2 to 54W, 3F5.
Step 4: Change of coverage for IOR (64E, 3F1) moving to EMEA (25E, AF1).
Coverage moves 40° westward
Original satellite’s identifiers (AORW/AORE/IOR/POR) will remain
The resulting network configuration will consist of:
Three I-4 satellites (4F1-APAC / 4F3-AMER and AF1 (EMEA)
One I-3 satellite (3F5-AORE)

New architecture
Initiated since January 2016 in close cooperation with Inmarsat and Cobham
The principle is to use NCS satellite interface as a virtual Remote Channel Unit
Terrestrial interface and host-computers remain at Marlink.
transparent for customers
Easy Roll back in case of implementation issue
Offer physical backup thanks to back-up NCS
antenna / network issue

11. Devices - Impacts Cobham/Sailor
JRC
- Mr Murata, from Japan Radio Co, LTD confirms that JRC Inmarsat-C will be able to use the Inmarsat-4
- JUE-80 series are for Land Mobile – Automatic Satellite search is inhibited
Waiting for Inmarsat & manufacturers report
Furuno
According to Furuno mother company, the migration should be transparent for all types of Furuno devices.
Trimble
This manufacturer stopped providing Inmarsat C devices for years. Expertise has been lost. No guarantee about the continuation of the service

12. MES impacts - Messaging
MES to Shore – Messaging:
The migration should be transparent for the MES
The MES selects the satellite it receives the best
The MES will always be under a satellite coverage
After the switch, the MES will scan and it will select the satellite it can view
It might face a short outage during the switch, nothing more expected
Shore to MES – Messaging:
The migration should be transparent for the user
The message will be received by the LES
The LES will be in charge of delivering it to the MES, whatever its location
The user might face delays, depending of the pending queue

13. Mobile Earth Station (MES) impacts - EGC
Enhanced Group Calling (EGC)
Safety Net – Fleet Net and System EGC
No change for:
The principle of EGC distribution
The logical denomination of the ocean regions
Commands used for the submission of EGC messages by customers
Change for:
The geographical coverage areas of the logical ocean regions
Approximate shift of 40 degrees westward of the coverage of a logical ocean region
Customers need to take care of
these changes in satellite footprints throughout the migration steps

Safety Net
Definition: Implementation of the EGC Broadcast service providing maritime safety-related information to the entire Inm-C mobile community
Metarea & Navarea zones – definition: Geographical sea regions for coordinating the transmission of meteorological information to mariners. They are part of GMDSS. Each region is identical to NAVAREAs
Geographical boundaries of NAVAREAs will not change
Change for:
The geographical coverage areas of the logical ocean regions
Approximate shift of 40 degrees westward of the coverage of a logical ocean region
No change for the end users

Distress calls - GMDSS
The migration has no impact on GMDSS operation
The Distress messages will be forwarded to the same and correct authorities
The Safety Net plan will be provided at a later stage

Impacts
Mobile login
Mobiles scan the sky  other/new coverage  automatic log-in (possible delay due to congestion)
Messaging
No concrete impacts on mobiles or shore-based users
Fleet Net (EGC)
No impact on an end-user perspective
Safety Net (EGC)
Polling
- Possible long pending queue at NCS level  delays
- Massive number of poll commands due to continuous transmissions generated by automatisms/robots creating long pending queue  delays
Data Reporting
- No DNID in the new coverage or no scheduling program  Mobiles stop reporting
- Delays in data transmission due to difficulties to send poll commands to the mobiles
