IsatM2M Satellite Service Extension

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Inmarsat, with ORBCOMM (previously Skywave), had previously communicated that the IsatM2M satellite service would be withdrawn on 31 December 2020.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

Until then ORBCOMM have confirmed that they will continue to support the IsatM2M service on a "best efforts basis", “despite the inherent risk induced by certain aging network elements”.

In short, the legacy units associated with the IsatM2M network, such as the DMR800, will continue to function come January 2021. However, there remains a concern that “a best efforts basis” may prove insufficient to support the critical position reporting services that rely on it. Therefore, Pole Star recommends continuing the migration to new units as soon as is practical.

To ensure service continuity, all tracking and telemetry services including Ship Security Alert Systems using associated DMR-800 transceiver hardware must be replaced and upgraded to operate over the latest and higher-performance IsatData Pro satellite service before this date.

IsatData Pro is the fastest low-data rate satellite communications service specifically designed to connect people with equipment and enterprise applications—anytime, in the world’s most remote locations. IsatData Pro offers enhanced reliability and the ability to deliver more data then other satellite M2M services in the market.
