1.3 Use and precautions

Although the VNet series (ground-based) GNSS receiver is based on

military standard design, it is anodized with an aluminum alloy, but the

precision instruments require careful use and maintenance.

WARNING: The receiver must be used and stored within

the specified environment. Please refer to the Appendix:

VNet product technical performance parameters table.

Avoid using the receiver in extreme environments.

The VNet6 Plus (ground-reinforced) GNSS receiver uses anodized

aluminum alloy for the shell, but should also be kept as dry as possible.

And in order to improve the stability of the receiver and extend the service

life, please avoid the receiver exposed to extreme environments, such as:

1. Damp

2. The temperature is higher than 75 ℃

3. The temperature is less than -40℃

4. Corrosive liquid or gas

Surveying the world,Mapping the future.

ADD: Building13, Tian’An Technology Zone HQ center, No.555, the North of Panyu RD, Panyu District 511400, Guangzhou,

China.

Do not place the GNSS antenna near sources of electricity and strong

interfering signals:

1. Oil (spark plug)

2. TV and computer monitors

3. Generator

4. Electric motorcycle

5. DC - AC power conversion equipment

6. Fluorescent light

7. Power switch

When selecting the position of the GNSS reference station for continuous

operation, notice the following:

The site should be easy to place the receiving device and have a wide field

of vision. Field height above 10 degrees should not have obstacles, so as

not to absorb or block the GNSS signal, as shown in Figure 1-1:

Figure 1-1

1.Near the site should avoid the large area of water or strong interference

with the satellite signal, to reduce the impact of multi-path effect.

2.The site should be away from high-power radio transmission sources

(such as television stations, microwave stations, etc.,) it's better to keep a

distance more than 200m; away from high-voltage transmission lines, the

distance should more than 50m to avoid electromagnetic interference on

the GNSS signal.

3.To provide a stable device to fix the antenna.

4.To provide reliable and stable power supply and communication network.

5. Suitable placement and protection of GNSS reference station equipment.

6.Select the traffic developed place, easy to arrive for inspection and

Note：1. Make sure set right baud rate, data bits, stop bits and check bits,

otherwise, would reveal wrong message.

2. ‘Correction data’ is in connection with reference station working mode.

In base station mode, the correction data is the correction received by

receivers whereas GGA data outputted from receivers in rover mode.

Comms transmission (Network transmission)

Transmission table consists of:

Serial number: the order code for online transmission.

Utilization: showing the status of chosen online transmission (on/off).

Status: this status contains ‘connecting’ and ‘connected’ two options.

‘connecting’ indicates this transmission is trying to connect or cannot

connect. While ‘connected’ means the transmission is connected.

Network type: consists of cable line, Wi-Fi, 2G/3G.

Protocol: the network protocol adopted, consists of Ntrip Client、TCP/IP

Client、ZHD Client、UDP Client、SG Client、Ntrip Server、TCP/IP Server

and UDP in which Server ZHD Client and SG Client are Hi-Target

protocols.

1.LAN network connection

You can use the cable to connect the GNSS receiver with the LAN, input GNSS

receiver wired network IP address (default: 192.168.0.200) in the browser, then

enter the VNet series Web management system login interface.

Notice: GNSS receiver default wired local IP is 192.168.0.200. If

the local area network segment is 192.168.0. ×, and the LAN does

not use 192.168.0.200IP, the GNSS receiver can be directly

connected to the LAN, LAN access through the IP 192.168.0.200 login; if the

local network segment is not 192.168.0. ×, such as LAN network segment

192.168.1. × or other (that is, GNSS receiver IP different from network segment),

you must add the network which segment is 192.168.0.x.

At present, often use optical fiber or ADSL to connect the network. Optical fiber

is usually with a fixed IP, and ADSL is usually a dynamic IP. Please refer to the

local telecommunications department for specific charges for optical fiber or

ADSL Internet access.

GNSS receiver and INTERNET can be directly accessed, you can also map

through the LAN external network IP to access.

Directly access method is relatively simple, in the local connection under the

Internet protocol, click 【Advanced】, in the pop-up interface, input the IP address
and gateway into WAN IP and gateway, as shown in Figure 4-5 below.

Diagnosis analysis and troubleshooting of common faults

5.1 The system starts normally, while lock star light SV is off

1.Check the environment of GNSS external antenna, GNSS external antenna

installation is downward, whether reference to the instructions in the overview

and precaution for distribution and installation;

Surveying the world,Mapping the future.

ADD: Building13, Tian’An Technology Zone HQ center, No.555, the North of Panyu RD, Panyu District 511400, Guangzhou, China.

2.Check the registration code is expired or not, such as the validity of WEB

management system and if the body number become red, means the registration

code has expired, please contact related staff of HI-TARGET to apply for

registration code, and log VNet series Web management system registered

receiver;

3.Check the GNSS antenna cable at both ends and check the connection between

GNSS receiver and GNSS antenna is tight or not, if loose please tighten, and wait

for about 30 seconds;

4. Monitor whether the GNSS antenna cable is connected to the GNSS ANT port,

not the WIFI ANT port.

5.2 The GNSS receiver is working properly and the terminal software has been

deployed, but the network transmission status is connecting

1.Check the connected network mode, network protocol and IP address and port

is correct;

2.Such as the network mode for the 3G, check the network parameters of the 3G

network is open; and make sure the local network environment is right, you can

use your mobile phone to check it. Make sure the SIM card is Unicom 3G / 2G or

mobile 2G card, and the data traffic is normal, that is activated and no arrears.

5.3. GNSS receiver is working properly, network transmission is connected, but

the raw data output frequency is incorrect

Use the network debugging assistant to receive data to check the data output

frequency is correct or not, such as the output frequency is less than the seted

frequency，make sure whether to open a record of a data record, and record the

frequency is greater than or equal to the network transmission of raw data

frequency, and open the automatic removal function.

Establish several data records, at the beginning the recording is normal, but

become not normal later

1. The late record is intermittent; make sure whether the power supply is normal,

if the battery is 12V power supply, the battery voltage should not less than 10.5V;

if use switching power supply , make sure the output power is greater than 15W.

2. No record later; check whether the registration is expired, if not, check whether

the GNSS receiver lock satellites, if so check the space of storage capacity.

5.4 Network cable connection is normal, but can not log on and visit the VNet

series (ground enhancement) Web management system;

1.Make sure whether the computer settings are set according to the network

settings and wired network settings in the manual.

2. The computer can ping the GNSS receiver, but can not access; turn off the

firewall and anti-virus software.

3.Make sure the IP inputted is correct. If can't just double-click the [power button]

to see the current IP address.
