1 Product Overview
1.1 Key Features
The Iridium Core 9523/9523N is a voice and data transceiver module for the Iridium global satellite
network. It is designed to be integrated with field application (FA) hardware and software to produce a
solution designed for a specific application or vertical market. These solutions drive a wide range of
applications in industries such as Oil and Gas, Rail, Maritime, Aeronautical, Utilities and
Government/Military.
The Iridium Core 9523/9523N is designed to meet the regulatory requirements for approval for FCC,
Canada, and CE assuming an antenna with a gain of ~3 dBi and adequate shielding.
The Iridium Core 9523/9523N supports all Iridium’s voice and data services. Applications can be built to
use one or multiple services using the voice and data interfaces. The product provides the core
transceiver module. All other functions and hardware such as SIM card reader, keypad, display, power
supply antenna etc. must be provided by the Product Developer. The Iridium Core 9523/9523N consists
of the following:
 Iridium radio transceiver with 8 watt transmitter and dual receivers
 Call Processor function that implements the Iridium L-Band AIS protocol
 Iridium speech Vocoder
 Coaxial RF connector for the antenna
 40-way inter-PCB connector with the following interfaces:
o Digital audio interfaces
o DPL serial asynchronous control port
o Serial asynchronous interface for SIM
o Data/Fax port – serial asynchronous data plus 6 control signals
o GPIO control signals
o Power
The Iridium Core 9523N is a second generation version of the Iridium Core 9523 and is identical in form
and function to the Iridium Core 9523. This document applies to both the Iridium Core 9523 and Iridium
Core 9523N as indicated by the term ‘Iridium Core 9523/9523N’. Where the contents of this document
apply specifically to either the Iridium Core 9523 or Iridium Core 9523N then this is indicated by the use of
the terms ‘Iridium Core 9523’ and ‘Iridium Core 9523N’ respectively.
The Iridium Core 9523/9523N is described within this document as “9523/9523N” and “ISU.” All of these
terms refer to the same product.
1.2 Iridium Core 9523/9523N Packaging and Regulatory
