EPOCH 50 GNSS Receiver

Day after day, rugged and reliable

EPOCH 50 GNSS
Receiver

Spectra Precision® EPOCH® 50 GNSS,
Survey Pro, and Survey Ofce make a
complete, integrated system for precision
eldwork including cadastral, control,
location, and construction stakeout.

Multi-Constellation
GNSS Support

The Spectra Precision EPOCH 50 GNSS
system, with its 220 channels, makes
effective use of the GPS L1/L2/L2C/
L5, GLONASS L1/L2 and BeiDou B1/B2
signals for outstanding satellite coverage
and precise positioning. The EPOCH
50 GNSS receiver and antenna use
proven technologies to provide both an
extremely stable phase center and the
tracking of the new stronger L2C and
L5 signals. The overall combination of
these new signals, multi-constellation
support, and receiver processing power
provides consistent accuracy and
condence in results.

Integrated transmit/
receive UHF radio

The EPOCH 50 GNSS receiver has an
internal Transmit and Receive radio
modem so that any receiver may be used
as a base or rover. Use the internal radio
on a construction site for a quick and
easy setup. Plug in an external battery for
all-day operations. The EPOCH 50 GNSS
also supports external radio and cellular
modems for added exibility and range.
All receivers include Bluetooth
to communicate cable free with your
choice of world class Spectra Precision
data collectors.

Proven Technology

Designed with greater than 99.9%
reliability initializations, the EPOCH 50
GNSS provides fast, high quality results
in all supported survey modes including
RTK, Postprocessed Kinematic and
Static. Consistent accurate results, quality
construction, and affordable pricing make
the EPOCH 50 GNSS the ideal choice for a
productive business.

Survey Pro Field Software

The key to getting the most out of your
crews and your equipment is your eld
software. Spectra Precision Survey Pro
eld software is specically tailored for
your new EPOCH 50 GNSS, as well as all
other Spectra Precision survey equipment.
Choose from three different data collectors,
add the level of Survey Pro you need, and
go to work. Survey Pro is easy to use, yet
it still unlocks the full power of EPOCH 50
GNSS so you can concentrate on getting
the work done.

Manage Your Data

Spectra Precision Survey Ofce software
provides a complete ofce solution for
postprocessing GNSS data and adjusting
terrestrial survey data. Download or import
eld and reference data from a variety
of sources including the entire family
of EPOCH GNSS receivers, Survey Pro
and permanent reference stations via
the internet. Export your processed and
completed results directly back to the
eld or design software packages using a
variety of le formats.

Network Rover Capable

The EPOCH 50 GNSS rover solution
supports the numerous real time GNSS
reference networks now installed all over
the world. A real time network improves
productivity while at the same time
reduces costs, by eliminating the need
to set up a base station. The networking
process supported by Survey Pro eld
software and GSM/GPRS capable
Spectra Precision data collectors
ensures the best quality, location
independent correction data.

EPOCH 50 GNSS system is best

described as Simply Reliable.

The lightweight, ergonomic and

cable-free system combines the

ease of use of a rugged integrated

1 Accuracy and reliability may be subject to anomalies due to

multipath, obstructions, satellite geometry, and atmospheric
conditions. The specifications stated recommend the use of stable
mounts in an open sky view, EMI and multipath clean environment,
optimal GNSS constellation configurations, along with the use of
survey practices that are generally accepted for performing the
highest-order surveys for the applicable application including
occupation times appropriate for baseline length. Baselines longer
than 30 km require precise ephemeris and occupations up to 24 hr
may be required to achieve the high accuracy static specification.

2 May be affected by atmospheric conditions, signal

multimath,obstruction, and satellite geometry.Initialization reliabilityis

continuously monitored to ensure the highest quality.
3 Depends on SBAS (WAAS/EGNOS) system performance.
4 Below –20°C, external power must be used.
5 Three batteries supplied standard.
6 When used with Survey Pro, only 1 Hz and 5 Hz modes are

supported.
7 Not all protocols will work with all radio baud rates and channel

spacing.
