Pairing the Radio
Pairing the Radio
Your radio (HPTxxxBT) and the TRIUMPH-2 receiver come
from the factory already paired and ready to communicate
with each other out of the box. Once powered, both the
radio and receiver will show their blue LEDs lit indicating
their linked communications. Usually this only takes a few
seconds.
When you purchase a radio from Javad GNSS separately
from the purchase of the receiver, NetView is available to
establish their pairing. It can also be used in establishing a
pairing with multiple radios in the series which include: the
HPT901BT*, HPT401BT, HPT404BT and the HPT435BT.
* Note: The TRIUMPH-2 paired with the HPT901BT works as a UHF
base for the TRIUMPH-LS when the FH915 radio has been installed
at the factory on the TRIUMPH-LS.
Procedure
Step 1. Connect the TRIUMPH-2 to your PC using the USB ca-
ble: USB Cable, A / micro B, (3.3 ft / 1.0 m) [14-578156-01].
Power the TRIUMPH-2 on.
Step 2. Connect the HPTxxxBT to your PC via a serial port
or through a USB to serial adapter. Be sure to connect the
antenna before powering the radio on. Depending on your
radio, the following cable choices will then apply:

Step 3. If you have previously installed the USB drivers, Run
NetView and connect to the TRIUMPH‐2 before skipping
ahead to Step 4; otherwise proceed with the completion of
Step 3.
The very rst time that your TRIUMPH‐2 is connected to your
PC using a USB port and powered on, your Windows operat-
ing system will likely begin automatically searching for the
drivers and then prompt you indicating that the drivers will
need to be installed.
Click Close
Procedure for Driver Installation
Once installed, the drivers will allow your operating system
to create a virtual serial port whenever you’ve connected
your TRIUMPH‐2 to your PC via USB.
The USB drivers for the TRIUMPH‐2 can be downloaded from
our website: http://www.javad.com/jgnss/support/update.html;
scroll down the page and download jgnssusb.zip

Once the drivers have been successfully installed, power o
your triumph-2 and disconnect the USB cable from the PC.
Click Restart Now
Connect your TRIUMPH‐2 to your PC using a USB port (not a
USB hub) and power it on. Your Windows operating system
will now be able to automatically complete the installation
for the virtualization of that specic USB port.
Because virtualized serial ports are transitory and populat-
ed by Windows on-the-y as needed by a given device, their
names may not always be visible. You can conrm the iden-
tication of the virtualized port before launching NetView
through Device Manager.

Pairing the Radio
Make note which virtualized serial port your receiver is con-
nected to. In the example above, COM8 is shown, but your
system may show some other name. When your device is
turned o or unconnected, it will be removed from view. If
you use the same USB port the next time, the COM assign-
ment will be the same and once again visible.
That’s it - congratulations! Your GNSS USB drivers are in-
stalled and working. You’re now ready to launch NetView,
but you might want to review some basic concepts on pair-
ing Bluetooth devices.
HPTxxxBT Pairing Concepts
These concepts pertain to the HPT901BT, HPT401BT,
HPT404BT and to the HPT435BT. Many thanks to Vlad Zhu-
kov for his tutoring.
Each device has its own unique media access control (MAC) ad-
dress that allows network communications to take place. If a
device has more than one mode of communication, like the
TRIUMPH-2 does, there will be one unique MAC address for
the WiFi adapter and a second unique address for the Blue-
tooth adapter. The TRIUMPH-LS has a 3rd unique address for
its LAN adapter. Communications cannot take place if two
devices have the same MAC address.
Master Mode
The HPTxxxBT radio will automatically initiate a Bluetooth
connection to the TRIUMPH-2 provided that the Bluetooth
MAC address of the TRIUMPH-2 has previously been stored in
the memory of the radio. In this respect, the radio is said to
be in master mode.
Once paired, that specic TRIUMPH-2 will be the slave to that
specic radio and accordingly only accept the Bluetooth
connection from the master with its stored Bluetooth MAC
address.
If you have two, or more radios that are each congured in
master mode, avoid turning them on at the same time in
the presence of the TRIUMPH-2 as they will interfere with one
another.

To operate TRIUMPH-2 as RTK base station it could be equipped with Bluetooth® capable external radio like either
one of three UHF 406.1-470 MHz radio transceivers: 35W HPT435BT, 4W HPT404BT, 1W HPT401BT or license free
frequency hopping 902-928 MHz 1 W HPT901BT radio transceiver.
WARNING! To avoid serious damage of the equipment, do not use the radio without the antenna.
TRIUMPH-2 communicates with radio via Bluetooth wireless link. Up to 50 ft (~15 m) is the practicable range of
the communication between TRIUMPH-2 and HPT401BT/HPT404BT. Actually in the field they keep reliable con-
nection up to 130 ft (~40 m). TRIUMPH-2 and radio are paired at the factory, so they automatically connect together
after power applied.
To turn ON the radio without the internal battery, connect the external power using the cable included to the kit.
To turn ON the radio with the internal battery, either connect the external power or press and hold the power but-
ton for more than 5 seconds to operate from the battery. To charge the internal battery, connect the external power.

PREFACE
ARPs
During its rst year in existence, the TRIUMPH-2 had a special
distinction made by NGS, specically in regards to its an-
tenna calibration data. During the year 2014, NGS had two
dierent antenna models: one with the 25mm x 1/4” x 20
threaded adapter [10-590293-01] included and one without
it. The net result related only to the Antenna Reference Point
(ARP).
Beginning in January 2015, and in accordance with the
standardized denition that the ARP is the lowest non-re-
movable part of the antenna, NGS has removed the an-
tenna type model that had included the 25 mm x 1/4” x 20
threaded adapter in its ARP. Accordingly, as of January 2015,
NGS is listing only one model antenna type for the internal
antenna of the TRIUMPH-2; the JAVTRIUMPH_2A. This is the
rst distinction that users need to pay very close attention
to; specically, their HIs (ARPs) if they have recorded obser-
vations using the TRIUMPH-2 during the calendar year 2014
and then process those data after 2014.
PCOs and PCVs
Additionally, the second distinction that users need to be
aware of is the antenna calibration data for the internal an-
tenna has been updated. This separate distinction relates to
both Phase Center Oset and Phase Center Variation values
for the internal antenna of the TRIUMPH-2.
The original PCOs and PCVs that the NGS Antenna Cali-
bration team had initially determined in March 2014 have
been superseded by the highly precise values produced
after recalibration on a Geo++ robot. These so-called near-
eld calibrations included the use of the 25mm x 1/4” x 20
threaded adapter [10-590293-01] and is reected by the
sux Aattached at the end of the antenna model’s name:
JAVTRIUMPH_2A. Finalization was coordinated through the
International GNSS Service (IGS) in December 2014.
If survey work has been performed with the TRIUMPH-2 and
processed using the superseded NGS values and which had
critical elevation determinations, users are advised to reex-
amine those projects and to reprocess their data using the
superior antenna model published in January 2015.
Dierences in the elevation of surveyed points have been
reported to be as much as 7 cm as improper Phase Center
Variations will cause errors most notably in the vertical com-
ponent in precise GPS surveys.

For further reading on this general subject, please see the
excellent National Research Institute of Astronomy and
Geophysics (NRIAG) article: Inuence of GPS antenna phase
center variation on precise positioning, by Dr. Ahmed I. EL-Hat-
tab which appeared in NRIAG Volume 2, Issue 2, December
2013, Pages 272-277.
Measuring your HI
Beginning with the new standardized
ARP denition, all antenna heights are
to be measured to the lowest non-re-
movable part of the antenna. This
means that, for example, using a 2-me-
ter xed-height GPS pole, the correct
HI will reect the addition of the 25 mm adapter; i.e., 2.025
m. If the TRIUMPH-2 is setup on a standard tripod, measure
the slant height from the mark to the green triangle on the
side.
OPUS kindly reminds users of non-conforming antennas
like the TRIUMPH-2 and the TRIUMPH-LS that the adapter must
be added.
Please refer to the NGS Antenna Calibration webpage for addi-
tional information.

TRIUMPH-LS shown above with its slant height measurement
point (SHMP). The green triangle is also printed on the op-
posite side of the unit.
The display screen is the antenna’s north reference; that is,
the direction the antenna should be facing when doing pre-
cise surveying. Because the Phase Center Oset values for
both L1 and L2 are less than 1 mm in northing and easting
from the central vertical axis, there is negligible impact due
to improper orientation.
PREFACE
ARPs
The TRIUMPH-LS requires the 25 mm x 1/4” x 20 threaded
adapter [10-590293-01] to be used whenever the unit is
attached to a 5/8” x 11 threaded tting. The Antenna Ref-
erence Point (ARP) is the bottom of the TRIUMPH-LS. Accord-
ingly, always be sure to remember to add that 25 mm when
using a 2-meter xed-height GPS pole.
PCOs and PCVs
Beginning in January 2015, NGS is listing the model anten-
na type for the internal antenna of the TRIUMPH-LS as the
JAVTRIUMPH_LSA. Additionally, the antenna calibration
data for the internal antenna has been updated. This sep-
arate distinction relates to both Phase Center Oset and
Phase Center Variation values for the internal antenna of
the TRIUMPH-LS.
The original PCOs and PCVs that the NGS Antenna Calibra-
tion team had initially determined in October 2013 have
been superseded by the highly precise values produced
after recalibration on a Geo++ robot. These so-called near-
eld calibrations included the use of the 25mm x 1/4” x 20
threaded adapter [10-590293-01] and is reected by the
sux Aattached at the end of the antenna model’s name:
JAVTRIUMPH_LSA. Finalization was coordinated through the
International GNSS Service (IGS) in December 2014.
If survey work has been performed with the TRIUMPH-LS and
processed using the superseded NGS values and which had
critical elevation determinations, users are advised to reex-
amine those projects and to reprocess their data using the
superior antenna model published in January 2015.
Dierences in the elevation of surveyed points have been
reported to be as much as 2 to 3 cm as improper Phase Cen-
ter Variations will cause errors most notably in the vertical
component in precise GPS surveys1.
