Introduction
TRIUMPH-3 is the most advanced GNSS receiver
with an integrated antenna. It is based on our latest
generation 864 channel chip and capable to track
all existing and future GNSS signals. Additionally
TRIUMPH-3 is equipped with the Wi-Fi and Bluetooth
modules, the internal 4G/LTE/3G card (optional), UHF
transceiver (optional), easy accessible microSD and
microSIM cards, USB and Ethernet ports.

TRIUMPH-3 can receive and processes multiple sig-
nal types (including the latest GPS C/A, P1, P2, L2C
(L+M); GLONASS C/A, L2C, P1, P2; SBAS L1) improv-

ing the accuracy and reliability of your survey points
and positions, especially under difficult jobsite con-
ditions.
Several other features, including multipath miti-
gation and common tracking, provide under-canopy
and low signal strength reception. The TRIUMPH-3
receiver provides the functionality, accuracy, avail-
ability, and integrity needed for fast and easy data
collection .
When calculating an absolute position, a stationary
or moving receiver determines its three-dimensional
position with respect to the origin of an Earth-Center
Earth-Fixed coordinate system. To calculate this po-
sition, the receiver measures the distance (called
pseudoranges) between it and at least four satellites.
The measured pseudoranges are corrected for clock
differences (receiver and satellites) and signal prop-
agation delays due to atmospheric effects. The posi-
tions of the satellites are computed from the ephem-
eris data transmitted to the receiver in navigation
messages. When using a single satellite system, the
minimum number of satellites needed to compute
a position is four. In a mixed satellite scenario (GPS,
GLONASS, Galileo), the receiver must lock onto five or
more satellites to account for the different time scales
used in these systems and to obtain an absolute po-
sition.
Achieving quality position results requires the fol-
lowing elements:
