The Iridium 9604 IoT module integrates satellite, LTE-M (Cat-M1), and multi-constellation GNSS into a compact 16×26×2.4-mm form factor. Built on the u-blox SARA-R5 platform, it integrates Iridium Short Burst Data (SBD), cellular connectivity, and GPS in a single device, enabling cost-effective dual-mode IoT deployments for industrial, infrastructure, and mobility applications.

The module supports GPS, GLONASS, Galileo, and BeiDou, and operates across an industrial temperature range of −40°C to +85°C. Optimized sleep modes and a unified power architecture across all three subsystems support ultra-low-power IoT designs.

Independent control of the satellite, LTE-M, and GNSS radios allows application-defined, GNSS-informed connectivity decisions, from simple failover to advanced routing logic. A unified AT command set simplifies firmware development across all functions.

The 9604 features dual RF ports—one shared for Iridium SBD and GNSS and one dedicated for LTE-M—reducing board space and simplifying RF design. The beta program was oversubscribed, with participants reporting lower system cost and up to 60% PCB footprint reduction.

Commercial availability is scheduled for June 2026, with development kits available for evaluation. Reserve priority access on the product page linked below.
