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

modem operating modes are described in Table 1.
Table 1 Satellite Modem Operating Modes
1.4.2 GNSS Receiver
The GNSS receiver is a module peripheral that is either on or off.
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.

Mobile ID
Unpackaged Antenna
The unpackaged antenna met the following specifications when mounted to a rigid
structure. Note that the rigidity and strength of the mounting structure must be considered
to maintain or comply with these specifications.
3.12 Mobile Identification Number
Each modem has a mobile ID used to register it on the IsatData Pro network. The mobile
ID is a 15-digit alphanumeric identifier in the format NNNNNNNNSKYXXXX.
This section contains a number of guidelines to assist the OEM Integrator in building
their enclosure. It must be recognized that this section provides guidelines only and each
OEM Integrator must use their own discretion to finish the integration approach that
works for them.
4.1 Regulatory Guidelines
The OEM Integrator must recognize the importance of regulatory requirements for their
integrated design. These requirements can have a major impact on the product design
functioning and schedule. Further, as the regulatory requirements can be quite complex,
ORBCOMM recommends that OEM Integrators always seek the advice of a regulatory
expert prior to starting integration. This advice allows the OEM Integrator to properly
plan and schedule design and test requirements.
When the regulatory tests are defined, it is also important to identify authorized test labs
that are qualified to perform the required tests. Prior to a design, critical tests should be
identified. It is recommended that the OEM Integrator pretest any high risk critical
specifications early in the design stage.
4.2 Compliance
Refer to section 2 for compliance information.
4.2.1 Reference Power Supply
The internal power supply operates between 5.0 and 15.0 VDC. A full RF output requires
an input voltage above the minimum operating voltage.
4.2.2 Review Process
The OGi modem integration can be challenging as the modem is a sensitive receiver that
has stringent emission specifications.
To help minimize integration risk, ORBCOMM recommends that the OEM Integrator
consult with ORBCOMM and review the mechanical integration prior to starting a
detailed design.
4.3 EMI/EMC Guidelines
The modem and antenna form a highly sensitive receiver that can receive very weak
satellite or GNSS signals. The highly sensitive receiver can also pick up noise or other
interference. Components such as processors and support circuitry should be shielded
with good quality shielding. It is also recommended that RF coupling/bypass capacitors
be added to the power supply rail, as close as possible to the modem's power pin. Digital
interface devices should be shielded, and care must be taken to ensure the digital
interface cable does not run close to the antenna.
The modem is intended to be used in a larger system. The system must provide adequate
power (low noise and relatively high current) and must possess an electrical signaling
mechanism compatible with the modem. Ensure that the custom designed circuit board
does not create undesirable signals that can impact the performance of the modem. An
external antenna is required to complete the modem design.
Figure 21 Typical OEM Integrator Modem Design
4.3.2 Antenna Cable Guidelines
The OEM Integrator is responsible for designing a custom-made RF cable to connect
antenna and modem. The following recommendations provide some guidelines for RF
cable selection:
4.3.2.1 General Guidelines for Antenna Positioning
Antenna placement is important. When positioning the antenna consider EMI
performance of the integration product and visibility to the sky.
Depending on the EMI performance of the integration product, the satellite antenna may
need to be paced a distance away from the integration product.
The antenna must be positioned such that it has a good view of the sky and there is no
metal/circuit board nearby to interfere with or block the antenna.
4.3.3 Host Shielding
In a typical integration, the modem is controlled by microcontroller.
The microcontroller and supporting circuitry, such as memory, high speed data/address
bus, clock references and power supply sources are normally noisy and could potentially
affect the highly sensitive satellite or GPS receiver performance if the antenna is placed
too close to the circuitry.
The following guidelines are provided when building a microcontroller using the modem.
Microcontroller and circuitry should be fully shielded.
Digital interfaces such as serial ports, USBs and I2C along with their tracks
should be shielded.
Avoid running any digital interface connector and cable close to the antenna. Do
not route any metal or cable above the ground plane of the antenna card or above
the antenna.
4.3.4 Decoupling
The following are recommendations for the power supply and digital lines to reduce
emissions that could be picked up by the modem.
RF decoupling/bypass capacitors (22pF 0403 or 33pF 0603 typical) be added as
close as possible to the modem's power pin on the power supply rail of the
processor and high speed digital circuitry.
RF decoupling/bypass capacitors added on the interface power rails.
4.4 Maximum Current
It is recommended that the power supply be designed with a margin to supply the
maximum current required by the modem. Refer to sections 3.4.1 and 3.4.2 for maximum
current and inrush current requirements when designing a power supply.
4.5 Enclosure Design
The modem is not designed for outdoor environments. Consequently, the enclosure
typically requires a robust environmentally sealed enclosure that can house the modem.
The following guidelines are recommended for the enclosure design.
An IP67 rating5 or better for outdoor use.
Use enclosure materials that are transparent to L-Band (1-2 GHz) radio signals.
Lexan Resin EXL 9330 is a common recommended enclosure material, but there are
many other suitable materials.
The unpackaged standard antenna is supplied with a dielectric cap, a piece of plastic
over the ceramic patch antenna that helps to negate the effects of different enclosure
materials on the performance of the antenna. With the dielectric cap, the standard
unpackaged antenna can be placed as close as desired to the adjacent enclosure
material.
The unpackaged low elevation antenna is less sensitive to enclosure material
Do not use metallic paint or tinting that may be conductive.
4.5.1 Label Guidelines
The label on the modem includes its mobile ID. If the modem is placed inside of an
enclosure that is not intended to be opened, an exterior label must be affixed to the
enclosure, in a visible location.
When integrating the modem into an enclosure, you must do one of the following:
Provide visibility of the modem through a window.
Provide an easy way to get to the modem when an access panel or door is
removed.
Place a label on the outside of the final enclosure that contains the following
information:
A copy of the ORBCOMM logo
Text that indicates the enclosure contains a transmitter
The mobile ID
A list of all valid certifications (for example, ETSI, Industry Canada, etc.)
With this information on the enclosure, installers can readily identify the required
information.
4.5.2 Mating Connector Guidelines
Refer to section 3.1 for connector guidelines.
4.6 Modem Mounting Guidelines
As shown in Figure 22 the modem has a hole in each corner of the enclosure sized for
M2.5 hardware to secure the modem to an application card or other environmental
enclosure surface.
The modem inserts into the connector at an angle, and is held in place with screws and
standoffs that match the connector height. The standoffs and screws generally interface to
a ground connection on the host board. Mounting screws should be properly tightened to
0.80 N-m (7 pound-inches) of torque or as per the specifications of the connector
Manufacturer.
4.7 Unpackaged Antenna Mounting Guidelines
As shown in Figure 17 the unpackaged antenna has a set of four holes sized for M3.5
hardware to secure the antenna to an environmental enclosure surface. A second set of
holes at the corner of the card can be used for mounting with #4 hardware, but the holes
are tight fitting and tolerances need to be considered, so SkyWave recommends the larger
hole set for mounting.
The following section contains ORBCOMM's recommended installation guidelines for
installing the antenna. It is recommended that the OEM Integrator include these in the
installation guidelines for end users.
5.1 Antenna Mounting Guidelines
CAUTION Mount the antenna at
least 20 cm away from humans.
The following guidelines for mounting the remote antenna also apply to an OEM Product
that includes the unpackaged antenna where applicable.
For fixed installations ensure that the antenna is pointing toward the equator,
facing south if in the Northern Hemisphere and facing north if in the Southern
Hemisphere, and its line of sight to the sky (satellite) is clear of obstructions.
For a mobile installation, mount the antenna at the highest point on the vehicle or
vessel where it has a clear view of the sky (satellite) in all directions.
Do not mount the antenna near metal objects. The antenna can communicate with
the satellite through fiberglass, but not through metal. Metal causes interference
if it is above the antenna and within 10.2 cm from the top of the antenna. Respect
the 20° or -15° elevation angle requirement with metallic object. Ensure that the
antenna is at least 1.3 cm higher than the metallic surface in cases where it must
be mounted next to a vertical metallic surface.
Ensure that any paint above the antenna is non-metallic and non-metallic flake, if
the installation is under fiberglass or composite wind fairings.
Mount the antenna on a surface that does not exceed the antenna's maximum
operating temperature. Locating the antenna where temperatures exceed the
recommended range might compromise performance.
Do not mount the antenna close to an exhaust pipe due to the excessive heat and
the potential for the exhaust pipe causing satellite blockage.
Do not mount the antenna close to air horns or any tractor roof hardware
(for example, emergency lights) that could interfere with satellite
communications.
Mount the antenna on the driver's side of the vehicle, if possible, when there is a
possibility of strikes by overhanging tree branches.
Do not drill any holes before checking that you have room for the bend radius of
the low loss coax cable. For reliable operation, do not go below a bend radius of
1.3 cm. Measure the bend radius of the cable as shown in Figure 23.
Mount on a surface that is free from dirt, grime, water and grease to avoid
damaging the mounting surface or the vehicle’s paint.
Mount so that the cable end faces the rear of the vehicle.
5.2 Mount a Remote Antenna
Two mounting options are available for the remote packaged satellite antennas: screw
mount or silicone mount. OEM Integrators, who have included an unpackaged antenna
within their product, should apply any packaged antenna restrictions mentioned in this
section, to the mounting of their own product.
5.2.1 Screw Mount
If mounting a remote antenna the following tools and materials are required:
1. Find a location for the remote antenna following the guidelines provided in
Section 5.1.
2. Use the mounting template (APPENDIX A) or the antenna as a template, to mark the
location of the mounting holes.

incorporated in the installation. Secure the cable no more
than 15 cm from the antenna enclosure and at regular
intervals along its length as part of the installation to prevent
cable wear and eliminate strain on the terminal connector.
Damage to the terminal connector interface or cable might
otherwise result leading to hardware failure.
4. Apply waterproof sealing compound, such as RTV silicone, around the drill holes so
CAUTION Adhesive or silicone cannot block the air vent features shown
5. Secure the antenna in place with self-tapping screws or machine screws and nuts
depending on access to the mounting surface. The remote antenna might also be
mounted using adhesive or a high strength outdoor grade silicone when mounting
holes are not an option in the mounting surface.

Figure 24 Air Vent Feature
Note: The recommended torque specification is approximately finger tight plus a
45 degree rotation using an 8 mm wrench.
CAUTION Cable management and connector strain relief MUST be
5.2.2 Adhesive Mount
The remote antenna might also be mounted using adhesive or a high strength outdoor
grade silicone when mounting holes are not an option in the mounting surface.
Refer to the adhesive manufacturer's recommendations for application temperature,
application conditions, compatible bonding materials, and minimum curing times when
working with an adhesive. Failure to follow the manufacturer's guidelines could result in
the remote antenna separating from the mounting surface.
CAUTION Adhesive or silicone cannot block the air vent features shown
incorporated in the installation. Secure the cable no more
than 15 cm from the enclosure and at regular intervals along
its length as part of the installation to prevent cable wear and
eliminate strain on the terminal connector. Damage to the
connector interface or cable might otherwise result leading to
hardware failure.
5. Place some weight on the remote antenna while the silicone cures.
CAUTION Cable management and connector strain relief MUST be
incorporated in the installation. Secure the cable no more than
15 cm from the antenna enclosure and at regular intervals along
its length as part of the installation to prevent cable wear and
eliminate strain on the terminal connector. Damage to the
terminal connector interface or cable might otherwise result
leading to hardware failure.
5.2.2.2 Silicone Bottom Connector Mount
The following tools and materials are required if mounting a remote bottom connector
antenna with silicone.
Outdoor rated silicone adhesive sealant (GE RTV 108)
5/16” or 8 mm wrench
Drill
12 to 19 mm drill bit for a straight SMA cable connector
29 mm minimum drill bit (hole saw) for right angle SMA cable connector
Isopropyl alcohol or an equivalent
To mount the antenna:
1. Find a location for the remote antenna following the guidelines provided in
Section 5.1.
2. Drill a 12 to 19 mm hole in the asset surface (Figure 27) when using a straight
SMA cable connector. For a right angle SMA cable connector, drill a minimum
hole diameter of 29 mm.
Refer to the note in step 7 if the right angle hole is considered too large.
Figure 27 Drill Mounting Hole
3. Clean the asset surface with isopropyl alcohol or an equivalent product that does
not leave a residue.
4. Insert the cable through the hole, from inside the asset, and thread the cable
connector onto the antenna. Torque the connector finger tight plus a 45 degree
rotation using an 8 mm wrench.
5. Apply silicone around the hole in the asset and to the bottom surface of the
remote antenna.
Figure 29 Apply Silicone to Hole in Asset
6. Lower the remote antenna onto the mounting surface.
The straight SMA cable connector can be lowered straight down onto the
mounting surface.
The right angle SMA cable connector, not shown, must be pivoted down onto the
mounting surface to fit the right angle cable and connector through a larger
clearance hole. Additional care is required with this installation to ensure the
right angle cable and connector does not smear the silicone around the clearance
hole when attempting to pivot the antenna into position.
7. Apply a generous bead of silicone around the entire perimeter of the remote
antenna enclosure. The two vertical slots shown in Figure 26 are vent features
and must not be filled with silicone.
Note: If the large clearance hole required for the right angle SMA cable
connector is considered too large, you have the option to use a smaller
clearance hole in the mounting surface and install the cable from
inside the asset after the antenna has been adhered with silicone.
In this case, first confirm there is enough room from inside the asset to
thread the SMA cable connector by hand and clearance for the wrench
to apply the final torque.
Also note that the silicone used to mount the antenna must be fully
cured before the cable can be installed from the inside otherwise the
seal and mounting are compromised.
8. Place some weight on the remote antenna while the silicone cures.

CAUTION Cable management and connector strain relief MUST be
incorporated in the installation. Secure the cable no more than
15 cm from the antenna enclosure and at regular intervals along
its length as part of the installation to prevent cable wear and
eliminate strain on the terminal connector. Damage to the
terminal connector interface or cable might otherwise result
leading to hardware failure.
CAUTION Before drilling check the template against actual hardware for
dimensional accuracy. If it is not correct, DO NOT USE THIS
