Chapter2 Basic operations of G6
In this section, we highlight the basic operations of G6. It includes the installation of
bas and rover, the operation of keys, switching working mode and datalink, self-test.
All of these basic operations are simple and easy. But they are very important.
2.1 The installation of base and rover
The installation of base
1. Install the tripod on the chosen position, level it and attach the receiver into
tribrach.
2. Attach the transmitting radio antenna into the port “UHF” if the data link is radio.
3. Switch on the receiver and select the base working mode. If it is not correct,
please see next paragraph 2.3 for understanding how to select the correct
working mode or you can change it later using the handheld software.
4. Switch on the handheld and start the software for the radio channel
configuration and inserting the base coordinates, otherwise it is possible to make
the settings by Web UI function.
The installation of rover
1. Fix the bracket on the pole, fix the handheld to the bracket, put the rover on the
pole and attach receiving antenna into the port “UHF”, depending on the
connection used.
2. Power on the receiver and select the rover working mode. If it is not correct,
please see next paragraph 2.3 for understanding how to select the correct working
mode or you can change it later using the handheld software.
3. Switch on the handheld and start the software, then you can do the advanced
setting of the instrument and finally start the survey.
Note: If you want to take very accurate measures (around or below cm accuracy), we
recommend you to use another tripod also for the rover.

2.2 The operation of keys
There is a power key in the receiver, the operations are as follows.
Power key
The main function of power key is power on/off and confirm button.
Power on: when the Receiver is in the OFF status (no light), press the power key
for 2 seconds and release it, and then the receiver will enter the initialization
status. Then you will listen beep for three times and the voice broadcast the
current receiver status, it means the receiver powered on successful.
Power off: when the G6 receiver is in the ON status (power supply light ON),
press and hold power key for 3 seconds until all lights blink, then release the
power key and there will be a voice broadcast “power off”. Press the power key
to confirm, then G6 will be turned off.
2.3 Self-checking
If the indicators are abnormal or the receiver can’t work normally, for example the
Bluetooth can’t be connected, the radio mode can’t work, it can’t connect to the
CORS. Then you can use the automatic detection function, which is Receiver
self-checking. Self-checking will check GPS, radio, GSM, Bluetooth, WIFI and sensor.
During this procession, it has voice guide tell you whether it’s normal or not.
1. When the receiver is in powered on status, keep press the power key for 3
seconds until a voice broadcast “if you want to turn off the device”, then release
the power key. Keep press the power key again for 3 seconds until you hear a
beep, then there will be voice broadcast “self-check” and you could release the
power key (The new device should be self-checked once).
2. In the process of device self-checking, there will be voice broadcast the test
results. For example, if the wifi self-check is successful, voice broadcast “WIFI
self- check OK” and the led always on until the self-checking is completed. For
example, if the WIFI self-check fails, voice broadcast “wifi self-check error”, the
led will continue blink and the buzzer beeps until you restart G6. Self-checking

12
procedure lasts about 1 minute.
3. If each module led are ON (not blinking) and voice broadcast the self-checking
success (for example “self-check GPS OK” it means the modules could work
normally.
Note: After self-checking, built-in radio frequency will return to factory settings. If
necessary, please contact your local dealer to change the frequency to match your
usage.
2.4 Measure the antenna height
When we use G6 collect static data or set G6 on a known point as a base station,
the antenna height should be measured. Antenna height is actually the vertical
height of the phase center to ground measurement point. But there are differences
between different measure methods.
Base and Static mode antenna height measurement: You can measure from the
ground to the altimetry piece of the receiver, you can measure from the ground
(known point) to altimetry piece. In this situation you should select “Height to
altimetry piece”.
Rover mode antenna height measurement: Measure methods of rover mode
includes pole height, straight height and slant height.
(1) Pole height, the height of the carbon pole, we can read it from the pole, then
input to the software.
(2) Straight height, straight height it’s the antenna phase center height. Straight
height = the height from ground to bottom of Receiver + antenna phase
center to the bottom of receiver.
(3) Slant height, measure from ground to the altimetry piece of the receiver.
Select slant height in the software, then input the height you measured.
2.5 Sensor Calibrate
Activate tilt survey function is the first step, then it’s “Sensor Calibrate”. Some times
when you check “Sensor Calibrate”, it can’t be used. You should check
Configure—System Setting, make sure tilt survey function is opened.“Sensor
Calibrate” contains “Horizontal, Azimuth and Declination”, now describe them.

13
Tips: 1. In order to make sure the accuracy, don’t replace battery during
calibration
2. The pole should be set on the same point during all of the steps.
(1) Horizontal Calibration
Horizontal calibration is actually calibrating the E-bubble. Click “Adjust—Sensor
Calibrate—Horizontal”.
Figure 2-1
Enter horizontal calibration interface, you will see an electrical bubble in the
screen. Center the carbon pole, make sure the physical bubble of the pole is in center
place, then click “Adjust” in the screen. It has a prompt tone which means the
horizontal calibrate is finished.
Tip: Before calibrate, when physical bubble is in center, the E-bubble may be not,
it’s normal. Because the sensor has deviation before calibrate. But after calibration,
the physical bubble and E-bubble will be in center together.

Figure 2-2 Before celebration (left) after celebration (right)
(2) Azimuth Calibration
Click “Adjust—Sensor Calibrate—Azimuth”, then it will show the “Azimuth
calibration” interface.
Figure 2-3
As it shows in the interface, there are three steps to do, “Record Vertical, Record
Horizontal, Calibrate”. Record vertical and horizontal data is order to get enough
data to do the Azimuth Calibrate.
First step is “Record Vertical”, install the receiver to mini rotary table, as picture
shows. Then click “Record Vertical”, at the same time set the carbon pole on a point,
rotate the pole in a circle, the carbon pole is the center of rotation. The speed can’t
exceed 25°/s. Software will show a circle when you rotate the pole. Usually, when

15
you finish a circle, the software will show the picture and have a beep sound.
But sometimes, you had finished the circle and the software show the circle,
software doesn’t transmit a beep sound and it doesn’t show “Record Horizontal” is
successful. It means some place of the circle doesn’t have enough data (You can
check it from the software), you should rotate it again in the place without enough
data.
Figure 2-4
Second step is “Record Horizontal”. It’s almost same as step 1. The only difference
is this time the receiver is installed to the pole directly, just as the figure shows.
Others are same.

16
Figure 2-5
The last step is “Calibrate”. After step one and two, it will show 2 circles on the
screen. Then click “Calibrate”, it will calculate the parameter and ask you “Make sure
using the parameter?” Click “Yes”, the parameter will be applied.
Figure 2-6
(3) Declination Calibration
After “Horizontal Calibration” and “Azimuth Calibration”, now it’s the last
step—“Declination Calibration”. Click “Adjust—Sensor Calibrate—Declination” to
enter the interface. Declination Calibration also contains three steps, “Records Center,
Records Tilt and Calibrate”
Figure 2-7
(a) The first step is “Records center”. Keep the pole on the same point, make sure
the bubble is in center, click “Record center”, it will collect 10 center points.

17
Figure 2-8
(b) The second step is “Records Tilt”. In this step, you should collect tilt points in
4 direction, and in every direction you should collect 10 tilt points. There are some
conditions to do this step.
①The pole should set on the same points during all of the steps when you are
collecting tilt points.
②The tilt angle should be between 25° to 35°. This angle will show in the
controller screen, so you can check it directly.
③When you do this step, the controller should be fixed solution.
④Collect tilt points in 4 directions, East, South, West and North. It also has a
angle to show the direction. 90° is for East, 180° is for South, 270° is for West, 0° is
for North. When you do this step, the angle should be closed to those angles. In each
direction, the receiver should be stable station.

18
Figure 2-9
Follow these four principles, then you can collect tilt points in four different
directions. Each direction should has 10 points. As the picture shows, set the pole on
one point, when you do this step. The tilt angle is 25°~30°, and make sure the
receiver is stable to collect points.
Collect tilt points in four different directions:
Figure 2-10 East Figure 2-11 South

19
Figure 2-12 West Figure 2-13 North
After success record centers and tilts, then we should apply this parameter to
project. Click “Correction” to calculate the parameters, if it exceed the limit, we
should do the Sensor Calibrate again. If it doesn’t we can apply it. The software will
give message on the screen.
Click “Correction” to apply. Input the Antenna height, if you use the quick release
adapter, the height should be pole height + 0.04m. For example, the pole height is
1.8m, if you use quick release adapter, the height will be 1.84m. Then click “OK” to
use.

20
Figure 2-14
Then all steps of Sensor Calibrate are finished. You can collect points with this
function. It will make field work more convenient and reliable.
