Iridium Messaging Transport (IMT)
Iridium Messaging Transport® (IMT®) takes satellite IoT to new heights, providing customers with small- to moderate-sized IoT messaging through Iridium CloudConnect. Built for developers, it supports large-packet data, industry-standard protocols, and Pub/Sub capabilities through a wide range of Iridium Certus™ modules.
With IMT, scaling satellite-connected IoT apps is as simple as scaling any other cloud service.
Why IMT Stands Out
Cloud-Native
Designed for AWS workflows, serverless architectures, and automation tools like Terraform, CDK, and CloudFormation.
Flexible Message Sizes
Transfer packets from 1 to 100,000 bytes to support everything from small updates to complex data streams.
Topic-Based Messaging
Organize data by Topics with configurable priority, persistence, and queue size.
Pub/Sub Architecture
Familiar publish/subscribe model for event-driven, real-time communication.
End-to-End Security
Encrypted private connections between Iridium and AWS keep data fully protected.
Scalable by Design
Whether it’s 10 devices or 10,000, IMT grows with your deployment.
How it works
Connect
Devices communicate via Iridium Certus modules over our satellite network.
Transport
IMT manages data flow and converts it for AWS-native services.
Deliver
Messages arrive as JSON in Amazon SQS queues inside the customer’s AWS VPC.
Integrate
Work with Python, Node.js, Go, or any modern stack using familiar cloud patterns.
Real-world applications
Industrial IoT & Machine-to-Machine (M2M)
OTT Services
Edge Deployments
Resilient Workflows
