IsatM2M Satellite Service Update

It has been announced that the IsatM2M satellite service covering the Pacific Ocean Region will be withdrawn as of 30 December 2020. However, the remaining service has been extended for an additional year, with the new end-of-life date set as 31 December 2021.

Inmarsat, with ORBCOMM (previously Skywave), had previously communicated that the IsatM2M satellite service would be withdrawn on December 31, 2020. But now, in consideration of the ongoing global pandemic situation, Inmarsat has extended this service for an additional year until December 31, 2021.

ORBCOMM have now provided further information stating that the IsatM2M service for the Pacific Ocean Region (POR) is excluded from this extension, and service for this region will end on 31 December 2020.

This means that the legacy units associated with the IsatM2M network, such as the DMR800 or DSAS Mk1, will no longer operate whilst the vessel / transceiver is located in the North Pacific Ocean, Bering Sea, Sea of Okhotsk, Philippine Sea, Coral Sea, Tasman Sea, and South Pacific Ocean (Inmarsat I3 Pacific Ocean Region).

ORBCOMM have stated that they will continue to support the service on a "best efforts basis", despite the risk of aging network elements. We have raised the concern that ORBCOMM's support may prove insufficient for critical position reporting services, even outside of the POR and we have been advised that the service may be subject to transmission gaps.

Therefore, we recommend continuing migration to new units as soon as is practical.
