Iridium 9523N
Iridium’s smallest, lightest and most advanced voice and data transceiver module. Enables simplified global voice and data connectivity through the world’s furthest reaching satellite network.
Key Capabilities
Compact OEM satellite connectivity for embedded voice and data applications anywhere on Earth.
Global Iridium voice, Short Burst Data and Push-To-Talk services
Compact 32 g module for space-constrained OEM integration
Direct PCB integration using standardized board connectors
Low voltage operation with separate transmit power input
Supports single- and multi-channel communications designs
Compact Integration for Global Voice and Data
Iridium Core 9523 is designed for OEMs building satellite-connected equipment where space, weight and integration flexibility matter. The compact module mounts directly to the host application board and supports Iridium voice, Short Burst Data, Circuit Switched Data, RUDICS and Push-To-Talk services through a single transceiver.
Its standardized connectors and shared component design help simplify development of single- or multi-channel products for maritime, aviation and land mobile communications, as well as handheld terminals and unattended systems. With pole-to-pole Iridium coverage, the finished product can maintain voice and data communications far beyond terrestrial networks.
