Iridium 9523 Core Transceiver Module

The new Iridium Core 9523 is a small, light, powerful state-of-the-art voice and data satellite transceiver module.

Its compact footprint and simple connection overlay offer our partners new communications opportunities to integrate Iridium directly on their printed circuit boards and develop products in order to meet the wants and needs of previously untapped consumer and vertical markets like never before.

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. 

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
