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.
Figure 1 Messaging Gateway
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.
IsatData Pro provides the following key features and benefits:
Two-way communication
Messaging to a host connected to the modem

Broadcast messages
Low latency messaging
Up to 6,400 bytes from-mobile messages for the AT Interface; up to 6,000 bytes
from-mobile messages for the OG Interface
Up to 10,000 bytes to-mobile messages for the AT Interface; to-mobile messages
for the OG Interface are truncated
Acknowledged messages
Global service
1.2 OGi Modem
The OGi modem provides easy integration and the highest level of EMI/EMC shielding
that reduces integration risk when the modem is co-located with other electronics.
Figure 2 OGi Modem
1.2.1 Remote Antennas
Two passive antenna types are available: a standard antenna (Figure 3) and a low
elevation antenna (Figure 3). The standard antenna has an elevation angle of 20 to 90°
and the low elevation antenna has an elevation angle of -15 to 90°. The OEM Integrator
is responsible for providing a specific RF cable to connect the antenna to the modem.
Both the standard and low elevation antennas are:
Available with a side or bottom connector
Sealed for operating in outdoor environments
Provide four mounting tabs for installation
Available with an SMA connector
Available packaged or unpackaged

1.2.2 Unpackaged Antennas
Both antenna types, standard and low elevation, are also available in an unpackaged
form. Both feature an IPX connector for connection to the modem and four mounting
holes for installation.

1.3 Key Features and Benefits
The OGi modem offers the following key features and benefits:
Designed to be incorporated into an OEM Integrator's solution
Built-in GNSS receiver to provide position, speed and heading information
Broad operational temperature range
IsatData Pro message payload and latency capabilities
1.4 Operating Modes
1.4.1 Satellite Modem
For the most part, the modem operates independently from the host application. The
modem operating modes are described in Table 1.
Table 1 Satellite Modem Operating Modes
Operating Mode
Description
Transmit Mode
In transmit mode the modem is transmitting a signal to the
gateway.
Receive Mode
In receive mode the modem is attempting or actively listening to
the satellite (listening on the bulletin board channel or on a traffic
channel).
1.4.2 GNSS Receiver
The GNSS receiver is a module peripheral that is either on or off.

2 Compliance
At this time, all certifications listed in this section are pending for the OGi modems.
Once approved, these certifications and test results will be available to OEM Integrators
for use as a baseline for the certification approval of their enclosure.
However, the OEM Integrator is responsible for ensuring that their final enclosure
complies with all local regulatory requirements, and electrical and safety codes wherever
the enclosures are sold or used. As the OEM Integrator’s enclosure contains the OEM
Integrator’s power supply and possibly other circuitry that affects the modem, the OEM
Integrator most likely needs to perform additional testing or repeat some of the tests listed
below.

3.8.1 1PPS Signal
The 1PPS signal is available in the modem. It outputs a pulse per second by default,
provided a valid GPS signal is present. If the GPS signal is blocked, the 1PPS stops.
By default the GPS is only on when requested by the application or the network. For
constant time updates, the GPS must be on at all times.
