Product Description

Iridium Core 9523 Transceiver

Iridium Core 9523 is Iridium's smallest, lightest and most advanced voice and data satellite transceiver module ever, enabling simplified global voice and data connectivity through the world's furthest reaching network.

Over 90% more compact than our previous model and featuring standardized connectors, it easily integrates into new partner products to reach previously under-served consumer and vertical markets - and drive global communications in ways never thought possible.

How It Works

New possibilities 

From single or multi channel communication platforms for maritime, aviation and land mobile markets to highly capable, feature-enhanced handheld smart devices and unattended sensors, the Iridium Core 9523 module delivers cost effective satellite voice and data communications.

Powerful capability

Iridium Core 9523 supports all Iridium voice and data services. It delivers the capability needed to develop innovative communications devices, and the technology backbone for applications such as GPS and location-based services, Wi-Fi and Bluetooth.

Simplified integration

Iridium Core 9523 features standardized connectors, simplified PCB integration and ultra compact form factor. Partners can easily mount Iridium Core 9523 directly onto their application board - enabling optimization through shared components and power sources.
