Iridium has introduced the Iridium Certus 9704 Module and Development Kit, powered by Iridium Messaging Transport (IMT) technology. This module, the smallest and most powerful from Iridium, is designed to support satellite IoT applications requiring real-time data analysis, analytics, and automated decision-making. It is ideal for use cases like predictive maintenance, diagnostics, telemetry monitoring, remote asset tracking, and command and control for aircraft, vehicles, and vessels.

The Iridium Certus 9704 simplifies data transfer with its IMT technology, which includes built-in topic-sorting to efficiently organize messages for delivery to the appropriate processing engine. This allows the module to handle various types of real-time data, including audio and images. IMT enables terminals to send and receive data over the Iridium network using standard terrestrial IoT/data transaction methods, streamlining the design, development, integration, and message management process.

Beyond IoT applications, IMT also supports machine-to-machine communications and over-the-top (OTT) services, such as email, group messaging, and weather forecasts, as well as other non-persistent data transactions. This makes the Iridium Certus 9704 a versatile solution for a broad range of satellite communication needs.
