2.3 Wi-Fi Password Setting

NeoRTK receiver can be used as Wi-Fi access point, supports user-defined password (Factory default
password: 12345678)

Cautions:
If you forget your password, you can reset your password by "GNSS Receiver Manager V1.0.3"??

2.4 Static data collecting

NeoRTK GNSS Receiver can collect static data. The steps are given below:

1. Set up receiver on a control point, centering and leveling strictly.

2. Measure the height of the receiver for three times, on condition that the difference of each

measuring is less than 3mm and the final height of the receiver should be the average height. Below

is the schematic.

Figure 19 Wi-Fi password

Figure 20 Static data collecting

24

Notice:

1. Instrument height should be measured from control point to the upper of measurement bench
marker.

2. The height of phase center is 0.1018 meter.

3. The measurement bench marker radius is 0.130 meter.

Below is the schematic:

4. Record point name, receiver S/N, receiver height, beginning time.

5. Press power button to power on and double click power button to set static collecting mode; then

single click power button to confirm it.

Notice: The satellite lamp flashing means the receiver is searching the satellites. The satellites

are fixed once the satellite lamp stays lit on. Status lamp flashes due to your collection interval

set, which means an epoch will be collected every flashes.

6. Turn off the receiver after static data collected is finished and save the turn off time.

7. Download and post-process static data.

Caution：Don’t move the tripod or change the collecting set when the receiver is collecting data.

25

NeoRTK default settings will not record Rinex format data. Users can change settings by GNSS

Receiver Manager Software. Below is the GNSS Receiver Manager Software page.

3. Tersus-Survery software

Tersus-survey is the first measure software with high accuracy on Android system in 2017.

Tersus-survey software should run on Android 2.3.3 or above, can run on Tersus professional measurement
controller, general phone, pad and some other Android devices. Just copy the Tersus-survey APK to the
Android device and install it or do it by third party assistance software

6. Accessory

The chapter will introduce the appearance and application of main interface of receiver and

accessories. The following equipment does not represent all users purchased NeoRTK. According to

different configurations, the specific configuration shall be subject to the delivery order upon

purchasing.

6.1 Different Antennas

UHF base mode and UHF rover mode shall use difference antenna. The difference antenna of UHF

base mode is used to transmit UHF difference signal. The difference antenna of UHF rover mode is

used to receive UHF difference signal. 3G mode shall use 3G short antenna as right.

Difference antenna installation:

Grasp the fixed nut in bottom of different antenna with hand to install clockwise. On the contrary,

dismantle difference antenna anticlockwise.

41

Warning: when installing difference antenna, it shall rotate the fixed nut in bottom of difference

antenna with hand rather that grasping the upper side of difference antenna, or it will break off the

difference antenna.

Data Cable

Five-pin plug

Series interface

Five-pin plug: connect Five-pin socket of receiver

Serial interface: it is used to connect with computer serial port, update receiver firmware, set the

receiver, manage static data and set the radio.

Warning: 1. when connecting various plugs of receiver, it shall align the red point in line joint at

the red point in receiver socket, or it will damage the receiver socket and plugs of various lines.

2. When plug out the plug, directly grasp the sliding collar and pull out the plug with effort. It shall
not rotate the plug.

3. After using the cable, it shall place the cable in the place difficult for extrusion, in order to

prevent damaging the plug. When installing the difference antenna, it shall rotate the fixed nut

in bottom of difference antenna with hand, rather than grasping the upper side to rotate, or the

difference antenna will be in bad contact and influence the operating range.

4. This cable is not standard, it’s optional, please contact saels if you need it.

6.2 DDTHPB External Radio

DDTHPB external radio is a type of radio improving the performance of relay radio UH-3000.

DDTHPB radio has all functions of URS relay radio. Compared to other radios, it is also

functional in power transposition protection. Even though the external power is connected

wrongly, DDTHPB radio will not be burn out.

1. Field intensity/power voltage indicator D1

2. Dibit nixie tube indicator D2

3. Send-receive indicator light D3

4. Power/warning indicator D4

5. Key K4 (power on-off key)

6. Key K4 (channel increasing key)

7. Key K3 (channel decreasing key)

8. Key K2 (electric quantity checking key)

9. Key K1 (power toggle key)

10. Power indicator light D5

43

DDTHPB radio interface:

1. Base host to radio cable interface

2. External power interface

3. Transmitting antenna interface

As for the specific operations of DDTHPB external radio, please refer to its manual.
