TracVision G4-HP
Technical Manual Addendum
Sky Mexico Customers Only
(ECO #7247)
The following changes apply to Revision K of the
TracVision G4-HP Technical Manual (KVH Part Number 54-0147).
Installed Satellites
The Sky Mexico satellite TV service is broadcast via the PAS 9
satellite located at 58º West longitude. Therefore, the Sky Mexico-
configured antenna (KVH part number 01-0231-05HPT) is
programmed to track the following satellites:
If you choose, you can install any other satellite from the
antenna’s satellite library as Satellite B (following the procedure
in Section 2.9, “Installing Satellites Using the ADCU” on page 44).
However, please note that the antenna may not be able to find
your selected second satellite when you switch from PAS_9 to
Satellite B, since the satellite may not be viewable from your
location. For example, in Mexico, you can receive Sky Mexico signals
from PAS 9, but you cannot receive signals from DSS_101, which
provides DIRECTV service to the U.S.
Multiswitch Restrictions
If you need to connect more than two receivers to the antenna
system for PAS 9 service, you must use an active multiswitch
that generates a 22 KHz tone (for example, Spaun models
5602NF or 5802NF).

54-0147 Addendum to Rev. K
Satellite A Satellite B
PAS_9 NONE

LNB “Skew” Adjustment
Unlike most satellite TV signals in North America, which are
circularly polarized, the PAS 9 signal is linearly polarized, which
means it is transmitted in a certain orientation. Your Sky Mexico-
configured antenna is equipped with a special LNB that collects
these linear signals. To optimize reception, however, the LNB
must be oriented in the same way as the satellite signal. This
orientation adjustment is referred to as the LNB’s “skew.”
Figure 1 shows how skew determines the amount of signal the
LNB collects. The more signal it collects, the better the reception.
To set the skew, you simply need to rotate the LNB to the proper
angle, as shown in Figure 2.
The correct skew setting varies depending on your geographic
location, since the orientation of your antenna to the satellite
changes as you move. Follow the instructions on the following
pages to find the correct skew for your location and to adjust the
LNB’s skew setting.

Figure 1 How Skew Works
Figure 2 LNB Can Be Rotated to Adjust Skew

Finding the Correct Skew for Your Location
You can find the correct skew for your location by either:
A. Querying the antenna (by entering commands via
a laptop connection), or
B. Finding your location on the PAS 9 skew map.
Option A - Querying the Antenna
To find the correct skew, follow the steps below.
1. Turn on the antenna and allow the antenna to
initialize.
2. Press the center button on the ADCU until the
“Control Antenna?” screen appears.
3. Press the ENTER button to access the Control
Antenna Mode.
4. Press the NEXT button until the “Set Lat/Long?”
screen appears.
5. Follow the process shown in “Setting Latitude and
Longitude” on page 86 to enter your position into
the antenna.
6. After you’ve entered your position, press the
NEXT button until the “Restart Antenna?” screen
appears.
7. Press the YES button to restart the antenna.
8. Once the antenna has initialized, press the center
button on the ADCU until the “Get Antenna
Status?” screen appears.
9. Press the ENTER button to access the Antenna
Status Mode.
10. Press the NEXT button until the “Get Skew
Angle?” screen appears.
11. Press the YES button. The ADCU displays the
correct skew for the location you entered in Step 5.

Figure 3 ADCU Reports Skew Angle (Example)

Option B - Using the PAS 9 Skew Map
If you do not have a laptop, you can find the approximate skew
for your location using the map below.
When to Change the Skew
In general, if your LNB’s skew is set to within ± 8º of the ideal
skew for your location, the antenna should continue to provide
good satellite TV reception. However, if you travel to a location
in which your LNB’s skew differs by 9º or more, or if reception
degrades the further you travel, you should readjust the LNB’s
skew for your new location.
Example: If you traveled from El Salvador to Acapulco along the
coast, you wouldn’t need to change the skew, since the correct
skew is 66º for both locations. Even if you continued traveling
north to Cabo San Lucas, you should still have good satellite TV
reception, since the correct skew is 63º, a 3º difference. However,
if you traveled all the way to San Diego, where the correct skew
is 54º, a 12º difference, you might then need to readjust the skew
to enjoy satellite TV reception.

Setting the Skew
To set your LNB to the proper skew, follow the steps below.
1. Turn off the power to the antenna.
2. Remove the radome and set it aside in a safe place.
3. Loosen the two wing screws securing the LNB
within the choke feed, as shown in Figure 5.
4. Refer to the skew labels on the end of the LNB and
on the LNB choke feed (shown in Figure 6) and
adjust the LNB as necessary to match as closely as
possible the correct skew.
5. Retighten the wing screws.
6. Reinstall the radome.

TracVision G4-HP
Technical Manual Addendum
(ECO #7243)
The following changes apply to Revision K of the
TracVision G4-HP Technical Manual (KVH Part Number 54-0147).
“Instant On” Mode Default Setting Is OFF
The default setting for Instant On Mode is now OFF, not ON.
When Instant On is set to ON, the antenna skips the startup
process to immediately receive the TV signal, as long as the
vessel has not moved since the antenna was last shut off. See
Section 3.8, “Control Antenna Mode” for details.
Antenna Restarts After =CALGYRO Command
When the antenna receives an =CALGYRO command, it
calibrates the gyro then restarts. This eliminates the need to enter
a ZAP command following the calibration process.
If you need to calibrate the gyro, follow the updated procedure
below. This procedure replaces the “Calibrating the Antenna
Gyro” instructions in Section 5.6, “Replacing the Antenna Gyro
Assembly.”
1. With a PC connected to the ADCU’s maintenance
port, apply power to the antenna unit.
2. Type HALT<cr>>(<cr> = Press the ENTER key)
while the system is performing the limit switch
initialization routine.
3. Type DEBUGON<cr> to enter Debug mode.
4. Type =LSTEST<cr>.
5. Type EL,300<cr>.
6. Type =CALGYRO<cr>.Verify that the Antenna
Gyro Azimuth scale factor is between -0.00090 and
-0.00110 and the Antenna Gyro Elevation scale
factor is between 0.00090 and 0.00110.
The antenna restarts. The gyro calibration process is
complete!
1
54-0147 Addendum to Rev. K
If your vessel is moored in calm
waters, you might be able to turn
on your receiver while leaving the
antenna turned off. As long as the
vessel has not moved since you
last turned off the antenna, you
might still get good TV reception.
However, once the vessel moves
and reception is lost, you will then
need to turn the antenna back on to
reacquire the satellite and resume
active tracking.
Refer to Section 4.6, “Computer
Diagnostics” for details on
connecting a PC to the
maintenance port.

1.1 TracVision G4 System Overview
A complete satellite TV system, illustrated in Figure 1-1, includes
the TracVision G4 antenna unit connected to the GyroTrac digital
gyro-stabilized sensor, Advanced Digital Control Unit (ADCU),
an IRD (satellite TV receiver), and a television set. A desktop or
laptop computer is used to conduct diagnostics. System
specifications are provided in Appendix A on page 123.
System Compatibility
The TracVision G4 satellite antenna is fully compatible with
Digital Video Broadcasting (DVB®) satellites, as well as
DIRECTV®‘s Digital Satellite Service (DSS) satellites. The
system is also fully compatible with KVH’s TracNet™2.0 Mobile
High-speed Internet System (for more information about
TracNet 2.0, please visit our web site at www.kvh.com).
In-motion Tracking
The TracVision G4 uses a state-of-the-art actively stabilized
antenna system. Once the satellite is acquired, the antenna gyro
continuously measures the heading, pitch, and roll of your vessel
and sends commands to the antenna motors to keep the antenna
pointed at the satellite at all times.

Satellite Library
Your TracVision G4 includes a pre-programmed satellite library
of North American and European satellite services. When
configuring the TracVision G4, you may choose a pair of satellites
from the library to be active in the system and with your IRD.
For the antenna to track and receive signals from two satellites,
they must be within 10º longitude of each other in orbit. As a
result, certain satellites can be paired only with certain other
satellites. Tables 1-1 and 1-2 list the possible satellite pairs that
may be selected in North America and Europe. If the satellite
service you wish to receive is not listed in the satellite library, you may
add two additional satellites of your choice to the library.
TracVision G4’s default satellite
pairs are:
N. America (US DIRECTV):
DSS_101 & DSS_119
Europe: Astra 1 & Hotbird

1.2 TracVision G4 Components
Your TracVision G4 system includes the following components:
Antenna Unit
The antenna unit houses the antenna positioning mechanism, low
noise block (LNB), power supply, and control elements within a
molded ABS radome. Weathertight connectors on the bottom of
the baseplate join the power, signal, and control cabling from
belowdecks units.
GyroTrac
TracVision G4 includes KVH’s GyroTrac digital gyrocompass for
three-axis attitude/heading reference, ensuring superior open
water performance in any sea conditions. GyroTrac can also
operate as a fully functional, stand-alone heading sensor.
GyroTrac includes the following two components:
Sensor Module
The sensor module houses the system’s compass/yaw sensor,
inclinometer, rate gyros, and processing electronics and is
waterproof to a depth of one meter.
Advanced Digital Control Unit (ADCU)
The ADCU is the user interface, providing access to the system
and its functions through an LCD and three soft keys. The ADCU
also serves as the system’s junction box, allowing the system to
use ship’s power, interface with the sensor module, supply and
receive data to/from the TracVision G4 system, and supply and
receive data to/from other shipboard systems.
Integrated Receiver Decoder (IRD)
(Satellite TV Receiver)
The IRD (purchased separately) receives satellite signals from the
antenna unit for signal processing and channel selection, and
sends the signals to the TV set for viewing. Please refer to the
user’s manual provided with your selected IRD for complete
operating instructions.
