2.0 DESCRIPTION AND OPERATION
2.1. Introduction and Overview
The Gogo Video Processing Unit (GVPU) enables the Gogo Universal Cabin System (UCS) to distribute
and control both standard and High Definition video as well as stereo and high definition audio to typical
business aviation cabin monitors and speakers. This functionality enables UCS Vision (movies, moving
maps, news clips, weather updates) to be displayed on a permanently mounted cabin monitor. The UCS
content server must be able to connect to the Internet externally for Digital Rights Management (DRM)
when playing movies or TV shows.
An installation comprises of the GVPU (P24486) LRU as seen in Figure 2.1.
Figure 2.1. GVPU
Figure 2.2 displays a diagram of the GVPU with an example of possible aircraft IFE configurations.
The GVPU receives power from the 28 volt aircraft bus via a dedicated circuit breaker or the cabin
monitor circuit breaker if this simplifies installation.
The GVPU outputs audio in S/PDIF format or analog format to the aircraft audio distribution system or
direct to the fixed cabin monitor depending on the aircraft configuration.
The video content is streamed from the UCS content server to the GVPU via a wired Ethernet port. The
GVPU outputs a composite video signal and/or an HDMI signal containing video data to the cabin monitor
based on user selection. The composite video signal exits via a D-sub connector. The HDMI link uses a
DVI-style connector which can be secured using the fixed jackscrews for use in a vibrating environment.

Figure 2.2. Sample GVPU Installation
The GVPU is mounted via holes in flanges at both ends of the enclosure.
The dimensions of the GVPU including mounting flanges are 3.23” W × 9.25” L × 1.33” H.
Description and Operation, Section 2 Page 2-3
Gogo Business Aviation confidential and proprietary D18340-A, May 2015
2.2. GVPU Indicators
The GVPU contains several internal LED indicators for power and general status. These are labeled on
the exterior of the GVPU and the location and function are shown on the Interface Control Drawing (ICD)
in Section 10 of this document.
2.3. GVPU Power
The GVPU must be installed within the aircraft pressure vessel. For an installation where the GVPU is
powered through a dedicated circuit breaker, a 1 Amp circuit breaker is recommended.
As the GVPU consumes very little power, installation may be simplified if the GVPU is powered by the
same circuit as the cabin monitor to which it will be connected. In this case, review the cabin monitor
power requirements and adjust the monitor circuit breaker size accordingly to accommodate the
incremental power draw of the GVPU.
2.4. Component Part Numbers

Refer to aircraft manufacturing guidelines and/or Advisory Circular 43.13-1B and 2B. Advisory Circular
43.13-1B (Acceptable Methods, Techniques, and Practices) Chapters 11 and 12, and Advisory Circular
43.13-2B (Acceptable Techniques, and Practices-Aircraft Alterations) Chapters 1 and 2, and SAE
AS83519 (Shield Termination, Solder Style, Insulate, Heat-Shrinkable, Environment Resistant, General
Specification For) and SAE ARP1870 (Aerospace Systems Electrical Bonding and Grounding for
Electromagnetic Compatibility) provide excellent guidelines to ensure a good installation.
A field-approved FAA Form 337, Supplemental Type Certificate (STC) or Type Certificate (TC) is the
usual required documentation path for the installation of this system.
3.2. Equipment Location
If this is a new installation of a GVPU, select cabling as specified in this manual to satisfy the approved
requirements of the system.
The GVPU must be located inside the pressure vessel. The LRU should be located near the cabin
monitor to which it will be connected to avoid long runs of HDMI cabling. The LRU can be mounted in
any orientation but be aware of any interference which may result between the electrical connectors and
surrounding cabling or aircraft structure. Refer to Section 7.0, System Specifications, for details
regarding the environmental requirements for this unit. Refer to Section 6.0 for mechanical installation
details.
3.3. Equipment Configuration
There are many variations in how the GVPU may be configured as part of the aircraft’s IFE system. The
configuration selected will be based on several factors which will include the customer’s requirements, the
type of cabin monitor(s) on the aircraft, the capabilities of the existing CMS and/or A/V Distribution
System, and how many existing audio/video resources are retained and need to be integrated with the
GVPU.
Installation Procedures, Section 3 Page 3-2
Gogo Business Aviation confidential and proprietary D18340-A, May 2015
3.3.1. Considerations Regarding Current System
Following is a list of questions to keep in mind when determining the optimal configuration for a specific
installation. They may be used as is or adapted to any particular situation based on the level of
complexity of the system.
Is there an A/V distribution System?
What type of Audio/Video Input does it have
Is there an available (unused) Audio/Video input.
Will the GVPU be connected directly to a monitor in the aircraft?
Is there more than one cabin monitor?
Is there an available HDMI or Composite input to the monitor?
How will audio from the monitor be distributed throughout the aircraft?
3.3.2. Sample Configurations
Following are some examples of possible installation configurations. These should only serve as
guidelines for actual installations as the final configuration will depend on numerous factors as described
above.
3.3.2.1. Single Digital Video Source
For an aircraft installation with no A/V distribution system, the GVPU will be installed directly to a cabin
monitor. Figure 3.1 shows a block diagram of this installation.
Installation Procedures, Section 3 Page 3-3
Gogo Business Aviation confidential and proprietary D18340-A, May 2015
Figure 3.1. Single Digital Video Source
3.3.2.2. GVPU as an Input Source to the CMS/A/V Distribution System
Many aircraft will have an existing CMS or A/V distribution system with a variety of audio and video
sources. In this case, the GVPU can be integrated to serve as an additional input to the existing system.
Figure 3.2 shows some examples of this configuration. Some aspects to consider when the GVPU is
integrated as in input source to the CMS or A/V distribution system:
If an aircraft is equipped with more than one cabin monitor and each is intended to display
individually controlled video, then more than one GVPU will need to be installed as input to the
CMS or A/V distribution system. In this case (more than one GVPU installed), each GVPU will
require a uniquely configured Internet Protocol (IP) address
If more than one GVPU is installed, each GVPU will need to be configured with a unique IP
address. See section 2.5 – General Purpose Input/Output for setting the IP address.
Installation Procedures, Section 3 Page 3-4
Gogo Business Aviation confidential and proprietary D18340-A, May 2015
Figure 3.2. Multiple Video Sources, GVPU Before CMS
3.3.2.3. Multiple Video Sources; GVPU after CMS
An alternative is to integrate the GVPU downstream or after the existing/upgraded CMS. This
configuration may be desirable if an HD capable cabin monitor is to be added solely to accommodate
digital video from the Gogo UCS system or other digital video content server. An additional application
provides the addition of HD video without changing the composite video source configuration and
connection to the CMS. Figure 3.3 shows some examples of this configuration.
Some aspects to consider when the GVPU is integrated after the CMS are:
Audio associated with HD video will only be available on cabin speakers unless the audio is
routed back into the CMS.
Audio volume control will be necessary at the amplifier unless audio is routed back into the CMS.
Installation Procedures, Section 3 Page 3-5

observe the following:
Installation Procedures, Section 3 Page 3-7
Gogo Business Aviation confidential and proprietary D18340-A, May 2015
1. Plan the GVPU cable routing so that it does not interfere with flight control cables or follow heavy
current-carrying cables, hydraulic lines, or fuel lines.
2. It is essential to use military specification connectors or connectors approved for use on aircraft.
3. This document, attached ICD and attached wiring instructions only show a suggested circuit
breaker size, wire size & type for a typical installation:
It is the responsibility of the installation agency to ensure proper wire type and size and the
use of a properly rated circuit protection device (circuit breaker). In addition, ensure that the
28 VDC equipment bus is connected so it can handle the additional electrical load.
Install circuit protection (circuit breaker) of the proper amperage to handle the power
requirements and protect the wiring.
Refer to aircraft manufacturing guidelines and/or refer to FAA Advisory Circular 43.13-1B,
Section 11 (Aircraft Electrical Systems) for the proper wire types and circuit protection
recommendations. All wiring and coax cabling shall conform to the flammability requirements
of FAR 25.869.
Single wire conductors shall conform to aircraft manufacturing guidelines and/or the
specification for Wire, Electrical, Fluoropolymer-Insulated, and Society of Automotive
Engineers (SAE)-AS22759, also known as Military (MIL)-W-22759.

Standard for Aerospace and Industrial Electrical Cable, National Electrical Manufacturers
Association (NEMA) WC 27500, also known as MIL-DTL-27500.
Size power wires and circuit protection to handle an operational voltage range 18.0 - 33.2
VDC with a nominal power draw of 7.6 watts @ 28 VDC and a maximum power draw of 14.0
watts @ 28 VDC.
The Wiring Diagrams in Section 10.0 provide manufacturing instructions for the wire harnesses. Notes on
the wiring diagrams provide essential instructions that will save you needless rework during installation.
NOTES
Component Bonding
As with any communication equipment, bonding the equipment to the airframe ground is essential
for optimum performance, compliance, and lightning protection. Ensure that the equipment
mounting provisions (tray or bulkhead mounting rails) are bonded to the shelf, and the shelf is
bonded to airframe ground. Properly bonded, there should be 2.5 milliohms or less between the
mounting tray and airframe ground. Care in bonding has been shown to eliminate erratic or poor
system performance.
Additional Shield Drain Information
As an option, up to four 22 American Wire Gauge (AWG) 7” drains may be combined on a single
grounding strap and then routed to airframe chassis. The ground strap should be as short as
possible, but may be realized with a maximum of 24” of insulated (18 AWG or larger).
4. To reduce EMI/RFI to an acceptable level, signal lines may require shielded cables. Refer to the
wiring instructions in Section 10.0.
Installation Procedures, Section 3 Page 3-8
Gogo Business Aviation confidential and proprietary D18340-A, May 2015
3.6. Antenna Mounting
The Wi-Fi antenna, used when the connection between the content server (UCS or other) is Wi-Fi instead
of hardwired Ethernet, must be installed such that 20 cm is maintained between the antenna and the
users under normal circumstances.
For optimal Wi-Fi performance, the Wi-Fi antenna should be mounted on a non-metallic surface and/or
secured with cable ties. The Wi-Fi antenna can be mounted to a metallic surface, but should have direct
line of sight (LOS) to the cabin in such a situation.
The Wi-Fi antenna is omni-directional but it is recommended to be mounted with the radome facing the
target area.
3.7. Remote Ground Maintenance Ethernet
Normally, the GVPU will be utilized in conjunction with the Gogo UCS system to display video content on
a cabin monitor or monitors. In this case, Ethernet access to the GVPU for configuration purposes can be
made through the aircraft network used by all the UCS system components. The UCS may be connected
through a Wi-Fi connection or the physical Ethernet jack on the GVPU. Instances where the GVPU is
installed in a location that is not easily accessible, and the Ethernet jack is not used for connecting to the
UCS system or other content server, it is recommended that the Ethernet port be wired to an easily
accessible bulkhead-mounted or panel-mounted RJ-45 connector. This will provide a hardwired Ethernet
connection to the GVPU for configuration and diagnostic purposes regardless of the status of the Wi-Fi
connection.

4.6. Maintenance
4.6.1. Inspection
The GVPU installation shall be periodically inspected as required by Title 14 of the Code of Federal
Regulations (14 CFR) Parts 43 and 91. The first inspection of the GVPU shall coincide with the first
scheduled aircraft inspection after its installation. Inspection task intervals shall follow inspection interval
tolerance guidance as outlined in the Aircraft Maintenance Manual (AMM). It is the responsibility of the
operator to ensure that the maintenance and inspection technicians have access to this guide as well as
the other previously noted documents.
The GVPU is to be maintained in an “on-condition” basis, however, it is recommended the system
components and wiring be monitored for general condition and structural installation integrity during their
respective area regular inspection intervals for the airframe. Consult the aircraft maintenance manual for
inspection criteria for areas where system components are located.
4.6.2. Mandatory Replacement Time
The GVPU allows for “on-condition” maintenance meaning that no periodic service requirements are
necessary to maintain continued airworthiness of the system. No maintenance is required until the
equipment does not perform its intended function. If component replacement is warranted, contact Gogo
Business Aviation Technical Support.
