IMPORTANT ANNOUNCEMENT: Repointing BGAN Land Terminals #1

14. Juli 2023 - 13:07:02 CESTVERÖFFENTLICHTMailversand: 2023-07-14 13:05:07

We are writing to inform you of Inmarsat’s decision to accelerate the intro­duction of their Inmarsat‑6 F1 satellite across the East Asia and Pacific region which means you or your customers will need to take some action to repoint BGAN Fixed Land Terminals to ensure service conti­nuity from their current terminal location.

Inmarsat are now planning for services to begin migrating from I‑4 F2 (MEAS) to I‑6 F1.

Following the completion of service migration from I‑4 F2 (MEAS) to I‑6 F1, I‑4 F2 (MEAS) will be relocated to APAC: restoring full capability and resilience in that region. This decision follows the 16 April 2023 outage on Inmarsat’s I‑4 F1 (APAC) satellite, which provides L‑band safety and other services over the region. While Inmarsat had restored most services by 18 April, others are still affected. With this in mind, to continue to deliver the level of service customers expect, Inmarsat will now accelerate the intro­duction of I‑6 F1.

Target dates and milestone as below (all 2023)June

Service migration has already started to move from I‑4 F2 (MEAS) to I‑6 F1


Intro­duction of BGAN on I‑6 F1, with mirgration of services from I‑4 F2 (MEAS) to I‑6 F1Performance impro­vement and capacity upgrades for BGAN, Swift­Broadband and Fleet­Broadband services in various locations across the region.

Q4 2023

Additional capacity for BGAN, Swift­Broadband and Fleet­Broadband for additional regions in the footprint.Full global service recovery for Classic Aero / Swift­Broadband Co-operative mode terminals.Additional capacity for global IsatPhone (GSPS) service.All services on I‑4 F1 (APAC) will transition to I‑4 F2 (MEAS) after its relocation from EMEA to APAC region during September – October.

ACTION(S) REQUIRED BY YOUTer­minal repointing – Currently pointing at I‑4 F1 (APAC) and still experi­encing an outage BGAN Land Terminals currently not receiving signal that are pointing at I‑4 F1 (APAC) can take one of the three following actions: 

You can wait until I‑6 F1 comes into service in early July and re-point the antennas still impacted to restore service. You will need to undertake a firmware update before you can repoint. Firmware will be released shortly, and when available, this will be shared with customers along with infor­mation and instructions.You can wait until I‑4 F2 (MEAS) takes the previously held position of I‑4 F1 (APAC) which will restore service in this area without the manual re-point requi­rement. This is planned to be completed by Q4 2023.You can choose to manually re-point your terminals now from I‑4 F1 (APAC) to I‑4 F2 (MEAS) to ensure service conti­nuity. This can be done immediately, however, I‑4 F2 (MEAS) is only available until Mid- August 2023, and will require you to re-point a second time when I‑6 F1 comes into service.

Terminal repointing – Currently pointing at I‑4 F2 (MEAS); needs to re-point before mid-August 2023 Terminals currently pointing at I‑4 F2 (MEAS) can either re-point to Alphasat or I‑6 F1 dependent on location. 

If the terminal can re-point to Alphasat from I‑4 F2 (MEAS)

Terminals that can re-point their antenna to Alphasat should do so as soon as possible. This activity can be carried out immediately and should be completed before 18 August 2023 to ensure service continuity. 

Please note, this option is not available for those terminals still impacted by the I‑4 F1 (APAC) outage.

If the terminal cannot re-point to Alphasat (I‑4 F4). 

Firstly, we require you to update the Firmware on your terminals. This can be done remotely prior to the re-point. Infor­mation to help you do this will be provided in due course when available from the manufacturers.

If re-pointing the antenna from I‑4 F2 (MEAS) to Alphasat (I‑4 F4) is impos­sible because of geogra­phical location or for any other reason such as obstruction, then you will need to re-point to I‑6 F1 once it comes into service but before I‑4 F2 (MEAS) starts to drift, to ensure service continuity. 

If the terminal cannot re-point to either Alphasat (I‑4 F4) or I‑6 F1

If the terminal cannot repoint to either Alphasat (I‑4 F4) or I‑6 F1, then unfort­u­nately you will lose service conti­nuity until I‑4 F2 (MEAS) reaches its new location in Q4 2023, and you can then point to this. This scenario should be appli­cable to a very small minority of the terminals in scope for this change.

This window of oppor­tunity to re-point to ensure service conti­nuity will be from 20 July 2023 until 18 August 2023. We under­stand that you may be disap­pointed by the inter­ruption and Inmarsat apologise for the disruption. We will continue to work with you provide updated infor­mation on progress on this accele­rated programme of work as and when it is made available to us. 

We thank you in advance for your co-operation and apologise for any incon­ve­nience this may cause.
