§1.3 Main Features
Intelligent Platform
New generation of embedded Linux operating system platform improves RTK performance and
work efficiency. Its operating efficiency is higher; a unique core processing mechanism which can
respond to more than one command at one time; it starts faster and more responsive in real time.
While the stability of system is much higher, it can be adapted to the job of longer uninterrupted
power.
Internal Web UI management
Embedded Web UI management platform supports WIFI and USB mode connection. Users can
monitor the receiver status and configure it via the internal Web UI management platform.
Bluetooth
Galaxy G2 is equipped with dual-mode Bluetooth v4.0 standard which is able to connect the other
smart devices and compatible with Bluetooth v2.1 standard. It not only enlarges the work range
but also makes the data communication become more stable.
WiFi
As the new feature and technology adopted on Galaxy G2, it not only can be used as data link to
access to internet, but also can be as a hotspot which can be accessed by any other smart devices
to configure the receiver.
Advanced InBuilt UHF module
Galaxy G2 adopts new and excellent datalink system, which is compatible with current radio
protocols in the market, and realizes the random switching of the radio range 410MHZ-470MHZ
and the power level as well. And the new protocol—“Farlink” is able to achieve the working
range as 8km.
Upgraded network module
Standard 4G module is integrated which supports TDD-LTE/FDD-LTE 4G network and
downward compatible with 3G and 2G network. Also supports all kinds of network types to
access CORS seamlessly.

Speed Dial
Smart PPP dialing technology can auto dial which makes the Galaxy G2 keeping online
continuously during the survey.
Intelligent Interaction
Support to access the internal web UI manage page of receiver with WiFi and USB connection,
monitor host state real-time, configure receiver freely.
Full Constellations Tracking
Equipped with most advanced GNSS boards, Galaxy G2 system can track most signal from all
kinds of running satellite constellation, especially support B1, B2 and B3 signal from BeiDou,
also get position result with only BeiDou signal.
Electronic Bubble & Tilt Compensation
Galaxy G2 is integrated with a new generation IMU module which makes tilt measurement more
stable, accurate and fast that without strict leveling the receiver to measure the point at will, it
helps surveyors boost productivity by 30 percent.
Worry-free surveying
The new generation of SoC platform gives RTK more stable performance and lower power
consumption. The built-in 6800mAh high-performance battery can support 15 hours of
continuous operation. G2 adopts Type-C charging interface which supports PD rapid charging, the
battery can be full charged in 3 hours that lasts full-day work.
Intelligent Storage
The raw data including STH, Rinex2.01 and Rinex3.02 not only can be saved in the internal
memory (8G SSD), but also can be stored into an external USB device (OTG). The configurable
sample frequency is really up to 20Hz.
Amazing Housing
With highly integrated and layered design, Galaxy G2 is smaller than typical Galaxy series
receivers. And coupled with the magnesium alloy body shell, the weight of G2 is only 850g
including internal battery, extremely light and convenient to carry.
NFC Function
The internal NFC module can make the complicated Bluetooth communication easier and more
simple.

ChapterⅢ Hardware Operation
§3.1 Power on/off
Power on
Press the power button for once, all the indicators glow in red, after few seconds (around 10
seconds), the instrument completes initializing along with voice prompt about the working mode
(for example, “Rover, internal radio mode”). After a while, instrument starts to track satellites.
Power off
Press the power button and hold for a while, after 3 beeps and the “Power off” voice prompt at the
third beeping, release power button, the instrument will switch off.
§3.2 Check working mode

ChapterⅣ Web UI Management
§4.1 Overview
Because of using the smart embedded Linux operating system and SOUTH intelligent cloud
technology, the web UI allows users to configure and monitor the status of Galaxy G2 in real-time.
The accessing way is not only by WiFi connection, but also can be USB mode.
§4.2 Access by WiFi
The WIFI hotspot is default broadcasted by Galaxy G2, search the WIFI hotspot which named
with SOUTH_xxxx using smartphone, tablet or laptop, then establish the WIFI connection, input
the default IP (10.1.1.1) into broswer, on the login interface, apply “admin” for the username and
password.
For example, search the WIFI hotspot broadcasted by a Galaxy G2 receiver using a laptop PC,
choose the WIFI hotspot and click on connect button to establish the connection without
password.

Galaxy G2

Run IE broswer on computer and input the default IP (10.1.1.1) into address bar, after a while, the
system login interface is refreshed, then apply “admin” for username and password to login.
§4.3 Access by USB
On this mode, the Type-C USB port of Galaxy G2 must work as an Ethernet port, then internal
web UI shall be accessed via USB cable connection with computer.
First of all, a corresponding driver is required to install to the computer, then this function could
be activated.
Due to different operating system is installed on computer, the drivers should be applied to a
suitable one. The file bugvista64.inf is applied to 64bit operating system, and linux.inf is for 32bit
operating system.
Make sure that the USB port (Type-C) is switched into USB network interface (please refer to
section 3.5, USB mode setting).
IP Address: 10.1.1.1

Choose the folder which contains the drivers

Galaxy G2
- 18 -
NOTE: The driver can be downloaded from official website automatically or please contact with
us for more supports.
If the driver has been successfully installed, the USB port of Galaxy G2 will be recognized as
Linux USB Ethernet/RNDIS Gadget, and a local area connection will generate in Network
Connections on the computer. For example, Local Area Connection 138 generates after
connecting Galaxy G2 receiver to computer via USB network interface.
However, sometimes the computer cannot detect the receiver by USB network interface because
there is something wrong with acquiring IP automatically, therefore, we need to do something to
avoid such problem, that is to set a fixed LAN IP for the connection:
Right click on the local area connection which newly generates, choose properties to call out the
local area connection properties window.

Galaxy G2

Then double click on Internet Protocol Version 4 (TCP/IPv4) option or click on properties button
to call out Internet Protocol Version 4 (TCP/IPv4) properties window, set the fixed LAN IP
address as shown in following, then click OK button and confirm the settings, return to the IE
browser and use the IP address 192.168.155.155 to access the internal web UI.
Run IE broswer on computer and input the default IP (192.168.155.155) into address bar, after a
while, the system login interface is refreshed, then apply “admin” for username and password to
login.

Remote Login
If users would like to remote login the web UI of Galaxy G2, then Galaxy G2 has to connect to
the internet and forward its 80 port to the public network. For example, if the IP address
222.196.35.76 is the public network IP which Galaxy G2 has connected, and the 80 port of
Galaxy G2 has been bounded with 8000 in public network, then users can input the public
network IP address into IE explorer along with the forwarding port for login. (http://
222.196.35.76:8000)
NOTE: The IE explorer is recommended to use for the Web UI login.
