Iridium's Next‑Generation Hybrid IoT Module and Development Kit are Now Commercially Available

The Iridium 9604 Module and Development Kit streamline global IoT development with integrated satellite, cellular, and GNSS connectivity

MCLEAN, Va., June 23, 2026 /PRNewswire/ -- Iridium Communications Inc. (Nasdaq: IRDM), a leading provider of global voice, data, and positioning, navigation, and timing (PNT) satellite services, today announced commercial availability of the Iridium^® 9604 module and Development Kit, giving developers, OEMs, and solution providers a faster path to build and scale connected IoT solutions worldwide.

Combining Iridium Short Burst Data^® (SBD^®) satellite connectivity, LTE-M cellular, and GNSS positioning, the Iridium 9604 module delivers a compact, integrated solution for global IoT deployments. Alongside the Iridium 9604 Development Kit, developers can rapidly prototype, test, and validate hybrid satellite, cellular, and GNSS applications with resources that simplify integration and streamline deployment workflows.

Built on the u-blox SARA-R5 platform, the Iridium 9604 is designed to reduce hardware complexity, lower integration costs, and accelerate time to market for connected solutions operating across industrial, infrastructure, transportation, mobility, utilities, maritime, and remote monitoring applications. The integrated design helps reduce board space requirements by 60 percent or more while simplifying RF routing, power architecture, and firmware development.

"The Iridium 9604 module and Development Kit represent a major milestone in making truly global IoT connectivity more accessible and easier to deploy," said Tim Last, executive vice president, Iridium. "By replacing three separate components with one integrated solution, developers can simplify device design, reduce costs, and create smarter, location-aware products capable of staying connected far beyond terrestrial coverage."

Early developers and beta participants reported significant operational and economic benefits from the platform's integrated architecture.

"The Iridium 9604 has enabled us to develop a truly global asset tracking solution without relying on terrestrial network infrastructure. Its reliable coverage, compact form factor, and straightforward integration have significantly accelerated our development process and allowed us to focus on optimizing the end-user experience," said Askar Gabit, CEO, GPSOne. "For applications in remote and challenging environments, the Iridium network provides the confidence that critical data can be delivered when it matters most."

The Iridium 9604 gives developers independent control over satellite, LTE-M, and GNSS subsystems, enabling flexible implementation of failover logic, location-aware connectivity decisions, and application-specific routing strategies. A unified AT command set and comprehensive SDK resources further simplify development and integration.

Built for scalable and power-sensitive IoT applications, the Iridium 9604 features a compact 16 mm x 26 mm x 2.4 mm form factor optimized for deployments where size, resiliency, and efficiency are critical. The platform supports GPS, GLONASS, Galileo, and BeiDou GNSS services alongside LTE-M (Cat-M1) and Iridium's 100% global L-band satellite network.

The Iridium 9604 represents the next evolution of Iridium's broader IoT strategy, expanding beyond traditional satellite-only hardware to support unified, multi-mode connectivity architectures. The Iridium network now supports multiple IoT pathways, including dedicated Iridium SBD modules, Iridium NTN Direct^SM standards-based direct-to-device capabilities, and larger payload connectivity through the Iridium Certus^® 9704 module.

Operating on the world's only truly global mobile satellite network, the Iridium 9604 delivers reliable connectivity across remote land areas, oceans, airways, and polar regions where other networks are unavailable or unreliable.
