Telemetry beyond
the cell network.

Match the link to the message profile.

Satellite IoT is not one service. It splits into message-based transports — a modem wakes, transmits a discrete packet, and sleeps on a multi-year battery — and IP-based links that behave like a slow, always-available network connection for SCADA, cameras and firmware distribution.

The engineering questions decide the service: payload size per report (bytes or kilobytes), reporting interval, alert latency, available power, and whether the asset sits inside a geostationary footprint or needs the pole-to-pole coverage of Iridium's low-earth-orbit constellation.

IMT is Iridium's cloud-native successor to SBD: message payloads from 1 byte up to 100 KB, organised into publish/subscribe topics and delivered straight into your cloud environment through Iridium CloudConnect — the same event-driven pattern as terrestrial IoT stacks.

The dedicated module is the surface-mount Iridium Certus 9704; Iridium quotes an 83% reduction in idle power draw against the 9603 SBD generation. The Certus 9770 carries IMT alongside its Certus 100 IP capability.

Bare 9704 modules are developed under Iridium partner and certification programmes rather than sold off the shelf — a development kit exists for evaluation. Ready-built units based on the same modules are also available for direct integration with your application, with no board-level development required. Speak to our specialists to find out which route is best for you — bare module, development kit or ready-built unit — and we will map it with you.
