Inmarsat C – I3 > I4 migration Jean-Marc Duc | Senior Product Manager | Jan-18

Connect smarter. Anywhere. Warning! This presentation is subject to modifications and updates along the migration process in 2018. 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! 17-Feb-19 Connect smarter. Anywhere.

Connect smarter. Anywhere. 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! 17-Feb-19 Connect smarter.

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) Timetable Step1: 04 April 2018 17-Feb-19 Connect smarter.

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 Others 17-Feb-19 Connect smarter. Anywhere.

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 17-Feb-19 Connect smarter.

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 17-Feb-19 Connect smarter.

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 17-Feb-19 Connect smarter.
