OGi Modem - Hardware Guide
© ORBCOMM Proprietary 9 T401, Version .15
1 Overview
The OGi modem is an L-Band mobile device and provides either an AT interface or an
OG interface for command and control. Hardware using an AT interface operates on the
IsatData Pro gateway while hardware using an OG interface operates on the ORBCOMM
gateway. ORBCOMM’s turn-key OEM solutions are intended for early integration into
M2M applications.
An OGi modem contains a satellite transceiver and a GNSS receiver, and requires a
specific passive antenna. The modem accepts commands and returns responses via a
serial interface.
The modem is suitable for both industrial and fixed applications such as:
Transportation and Distribution
Fleet management and security
Asset tracking, monitoring and control
1.1 Overview of the Messaging System
The IsatData Pro service allows OEM Integrators to offer particular applications and/or
services to their clients. As shown in Figure 1, the OEM Integrator communicates with
the modem through a centralized gateway. The gateway is the communications hub of the
system, controlling access to the modem and routing traffic to the modem, regardless of
where it is deployed in the world.

Configuration and data retrieval from the modem can be easily accomplished through
Internet-based application services provided by OEM Integrators or by integrating
existing customer enterprise software to receive information from the Gateway.
