§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 G7 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 G7, 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 UHF module
GALAXY G7 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.

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, G7 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
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.
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.
Ultimate portability
Highly integrated GNSS antenna, Bluetooth module and WIFI module, leading the design trend of
miniaturization, light weight, and portable RTK to a new height. Magnesium alloy housing, tough

ChapterⅢHardware 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
Press the power button for once in the state of power-on, the instrument will prompt with voice
message about current working mode (for example, “Rover, internal radio mode”).
§3.3 Charging
Insert the connector of G7 charger into 5-pin LEMO interface on G7, and plug the adapter to the
power socket, while the power indicator glows in blue, that means the inbuilt battery is being
charged.

ChapterⅣWeb 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 G7 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 G7, 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 G7 receiver using a laptop PC,
choose the WIFI hotspot and click on connect button to establish the connection without
password.
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 7-pins USB port of GALAXY G7 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 is switched into USB network interface (please refer to section 3.5,
USB mode setting).

Choose the folder which contains the drivers
NOTE: The driver can be downloaded from official website automatically or please contact with
us for more supports.

GALAXY G7

If the driver has been successfully installed, the USB port ofGALAXY G7 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
connectingGALAXY G7 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.
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.
