I-3 to I-4 migration: Update on the Inmarsat C migration date

[돌고래]

수고 많습니다

올해, 아래와 같이 단계적으로 INMARSAT 3세대 위성(INMARSAT-C & F77이 3세대 위성 사용)을 I-4 (FBB가 4세대 위성 사용) 및 I-3 F5(3세대 back up 위성)으로 Migration을 한다고 합니다

만약 이렇게 될 경우,

1. 현재 INMARSAT-C 기기에 해역별 위성을 선택하는 메뉴가 있는데 기기 Software upgrade 없이 사용하여도 되는지 확인 필요
   (예 : 현 INMARSAT-C 경우, 대서양West위성의 경우 기기에 “AOR-W”로 표시되어 있는데 이 위성이 “AMER” 위성으로 Migration 되고
   또한 위성 위치가 변경되는데 기기에는 계속 “AOR-W”로 표시된다면, 대서양 항해선박의 경우 사용자가 불편할 수도 있으며
   만약 “all ocean region”으로 설정되어 있지 않고 평상시와 같이 “AOR-W”로 특정 위성을 고정 설정하였다면 위성 위치 변동으로 인한
   수신감도 불량등 문제 발생 가능성 있음)

2. 각 NAVAREA 별 EGC(INMARSAT-C에 내장) 기능을 통한 MSI(해사안전정보) 수신에 문제가 없는지 확인 필요

3. SSAS 사용을 위하여 INMARSAT-C에 설정된 각 해역별 지구국 Code를 그대로 사용하여도 문제가 없는지 확인 필요

4. 육상 I-VMS에서 Data(Position) polling을 위하여 INMARSAT-C에 설정된 DNID등, I-VMS 시스템 사용에 문제가 없는지 확인 필요

5. 육상에서 사내 메일로 선박에 Telex 계정(INMARSAT-C)으로 보낼 수 있는데 이것도 문제가 없는지 확인 필요

6. 해역별 Migration이 되면 선박에, 위성의 위치 변동과 관련한 정보 및 참고사항등 제공 필요
   (3세대 위성 Coverage Map → 4세대 위성 Coverage Map & 3세대 back up 위성 Map 제공 필요)

• 상기 3세대 위성 Migration과 관련한 모든 정보는 같이 공유를 하면서, 각자 담당 항목에 대해서 확인해 보도록 해야 되겠네요.

  Update on the first migration dates

  Following our previous I-3 to I-4 migration notice issued in February, please find below an update on the dates for the first migration of services from the Atlantic Ocean Region West (AORW) I-3 satellite to the Americas (AMER) I-4 satellite.

  This migration will be performed in two stages:

• Migration of Fleet 77, Swift 64 and Classic Aero services is scheduled to take place on 30 April 2018 at 17:30 UTC (subject to final confirmation).
• Migration of Inmarsat C (to include Aero C and Mini C) services has been rescheduled to take place on 09 May 2018 at 14:00 UTC.

Our primary objective is to ensure that the transition process is as seamless as possible for our partners and customers.

The transition of services from the I-3 fleet onto our I-4 constellation will continue throughout 2018 and will take approximately nine months to complete. Our approach is to migrate all services (Inmarsat C, Fleet 77, Swift 64 and Classic Aero), satellite by satellite, as per the schedule shown in the table below.

I-3 to I-4 migration	Timing
Atlantic Ocean Region West (AORW) I-3 to Americas (AMER) I-4	Fleet 77, Swift 64 and Classic Aero services – 30 April 2018 at 17:30 UTC (subject to final confirmation) Inmarsat C (to include Aero C and Mini C) services – 09 May 2018 at 14:00 UTC
Pacific Ocean Region (POR) I-3 to Asia/Pacific (APAC) I-4	End Q2 2018
Atlantic Ocean Region East (AORE) I-3 moved from 15.5W to 54W (I-3 F5 satellite)	End Q3 2018
Indian Ocean Region (IOR) I-3 to Alphasat EMEA I-4	End Q4 2018

Due to the move from the I-3 to the I-4 satellites, the coverage areas will change and users will need to ensure that their devices are pointed to the relevant satellite. This process will generally be managed automatically by the terminal without the need for user intervention. However, in some instances, users will need to manually repoint their devices to the appropriate satellite.

• Inmarsat C users should ensure that their local applications (e.g. data reporting) will operate correctly if they are using a different Inmarsat satellite and are advised to contact their applications provider for any support.
• Classic Aero and Swift 64 users are advised to contact their equipment manufacturers to confirm‎ whether a configuration update will be required to support the migration.

Each migration step will cause a short outage while services are moved onto the I-4 satellites. Under supervision of the International Mobile Satellite Organisation (IMSO), the Global Maritime Distress Safety System (GMDSS) and Maritime Safety Services will be closely monitored during the migration, as will the Classic Aero Safety Service. These safety services will be restored first with the highest priority.

Final dates for the transfer of services of the POR, AORE and IOR will be confirmed approximately six weeks prior to the start of each migration to the corresponding satellite.

We will continue to communicate with you throughout the planning and execution phases of the migrations, providing additional details as and when necessary.

If you have any questions or concerns, please contact your Inmarsat representative, who will be able to assist.

Dear Inmarsat C Customers and Users

We are writing to advise you that the migration of Inmarsat C services from the Atlantic Ocean Region West (AORW) I-3 satellite to the Americas (AMER) I-4 satellite will now take place on 09 May 2018 at 14:00 UTC. 
 
We have taken the decision to reschedule the Inmarsat C services migration to allow additional time for customer readiness and further verification of the network infrastructure.
 
As you will appreciate, our primary objective is to ensure that the migration process is as smooth as possible with minimum disruption caused to our Inmarsat C customers and partners.
 
Please note that the migration of Fleet 77, Swift 64 and Classic Aero services remains on schedule to take place on 30 April 2018 at 17:30 UTC.
 
We thank you for your understanding and will continue to communicate with you throughout the planning and execution phases of the migration.

Additional information about the migration can be found on the Inmarsat website www.inmarsat.com/i3-i4-services-migration.
