non-xed position is called the rover. Relative to the
GNSS satellite signal of the rover, the data transmitted by
the base is called differential data, and the data transmission
method is called data link. The rover mode setting is to set
the GNSS as a rover, congure certain parameters to
transmit the GNSS satellite signal of the base station to the
GNSS device in a certain way, so that the GNSS device can
obtain a high-precision positioning.
In addition to differential data transmission
conguration, you can also set the GNSS cutoff angle,
differential delay, and whether to enable PPK and other
basic information, as shown in Figure 3.4-1. Adjust the
altitude angle to not receive the satellite signal when it is
lower than a certain value. In the case of poor satellite signals
at low angles, it is benecial to precision calculation. The
PPK parameter records the original GNSS observation data
to the GNSS receiver and uses the post-processing
algorithm to calculate high-precision coordinates.
The differential data parameter setting is mainly to set a
way to transmit the differential data of the base station to
the current device, so as to provide the necessary solution
conditions for the device to solve high-precision
coordinates. The data link methods mainly include Phone
Internet, Device Internet, Internal Radio and other methods.
1. Phone Internet: As shown in Figure 3.4-1, it refers to
obtaining differential data from the specied server address
through the network of the device where the software is
located according to a certain protocol, and then sending it
to the device through the communication connection
between the software and the GNSS device for
high-precision solution. Click on the right side of CORS
3. 4 Rover Mode Setting
Click [Device] [Rover], as shown in Figure 3.4-1.
GNSS positioning equipment can calculate positioning
coordinates by receiving satellite signals. In the absence of
other interferences, the positioning equipment can only
obtain the coordinate position of a single point solution due
to the interferences of the atmosphere on the signal, and the
accuracy is low. In order to ensure that GNSS devices can
obtain high-precision positions, in addition to the GNSS
device itself receiving satellite signals to calculate the
position, it is also necessary to receive the signal of another
nearby xed-position GNSS device, and use the signal of the
other device as the reference signal. Since the inuence of
the atmosphere on the signal is basically the same within a
certain area, when the coordinate position of the reference
signal is known, the two sets of GNSS can calculate the
high-precision position. The GNSS device with a xed
position is called the base, and the GNSS device with a
31 32
settings to enter the CORS server management interface,
as shown in Figure 3.4-2. You can directly select, edit, and
delete existing CORS servers, or manually add CORS server
parameters, as shown in Figure 3.4-3. After correctly
conguring the server address, obtain the access point list,
as shown in Figure 3.4-4, and select the corresponding
access point to obtain differential data. Click [Start], if the
conguration is correct, the data reception progress bar will
move. If there is no data in the progress bar, you need to
conrm whether the parameter conguration is correct.
2. Device Internet: As shown in Figure 3.4-5, it refers to
obtaining differential data from a specied server address
through the SIM card network of the GNSS device according
to a certain protocol for high-precision solution. The
connection mode is the transmission protocol of differential
data, usually by NRTIP, TCP client, etc., enter the server IP,
port, username and password and other connection
parameters. The SIM network is a dedicated network and
needs to congure APN parameters, as shown in Figure
3.4-6. The CORS setting is similar to the Phone Internet.
After correctly conguring the server address, obtain the
access point list and select the corresponding access point
to obtain differential data. In addition to obtaining access
points through the Device Internet, it can also be obtained
through the network corresponding to the mobile phone if
there is a mobile phone with a network.
3. Internal Radio: As shown in Figure 3.4-7, it means
receiving the differential data of the radio station according
to a certain protocol and frequency through the internal
radio of the GNSS device, and performing high-precision
calculation. At this time, it is necessary to ensure that the
protocol and frequency of the built-in radio station are
consistent with the protocol and frequency of the
transmitting radio station, so that the radio station data can
be received normally. If the frequency corresponding to the
channel is inconsistent with the channel frequency of the
transmitting radio station, you can click [Set Radio
Frequency] to modify the frequency corresponding to each
channel of the radio station, as shown in Figure 3.4-8.
4. XLINK: As shown in Figure 3.4-9, it is a differential
forwarding system built based on the CORS network of
Qianxun/ Liufen/ China Mobile. After conguring the Xlink
data link, the host can access the differential normally if it
can access the Internet, without the need for the customer
to manually ll in the CORS account.
Note: Each data link has the base coordinate change
alert turned on by default, because if the wrong base station
signal is received, the coordinates may be inaccurate,
reminding the user to check and conrm.

3.5 Base Mode Setting
Click [Device] [ Base], as shown in Figure 3.5-1. This
function is that the GNSS device acts as a base to send
satellite information data in a certain way and provide it to
the rover to receive it, providing it with high-precision
solution conditions. The host needs to set the startup
condition parameters, startup mode and data broadcast
parameters as a base.
Note: During the startup of the base station, the device
is not allowed to move, otherwise the coordinates calculated
by the rover will be wrong.
The start-up conditions include Base ID, Diff Mode,
cut-off angle, PDOP limit and other parameters. Click
[Advanced], as shown in Figure 3.5-2, to congure cut-off
angle, PDOP limit and other parameters. The differential
data format includes CMR, RTD, RTCM23, RTCM30,
RTCM32, RTCM33 and other commonly used differential
data encoding formats;
The startup mode includes using Current coordinates,
inputting Base coordinates, etc., among which:
1. Use Current coordinates: This means that the GNSS
device outputs differential broadcast data for the startup
coordinates based on the current positioning value (with low
accuracy);
2. Input Base Coordinates: refers to the location where
the user sets up the equipment. The user knows the
coordinates of this location in advance and uses this
coordinate value as the starting coordinate to output
differential broadcast data. Click [ Specify Base Station
Coordinates] to enter the interface for setting base station
coordinates, as shown in Figure 3.5-3. You can click the
35 36
measurement icon to measure a point in real time, or
click to select a coordinate value from the coordinate
point library.
The data broadcast parameters are mainly the
differential data output by the device after starting the base
station, which is transmitted through a certain method and
received and used by the rover. The main methods include
device Internet, built-in radio, external radio, etc. The
parameter settings are similar to those of the rover, with the
following differences:
1. The internal radio has a transmission power. The
higher the transmission power, the longer the effective
distance, and the greater the power consumption;
2. Device Internet NTRIP protocol, the base station is
the base station access point that sets the start of
transmission, as shown in Figure 3.5-1, and the rover obtains
the access point list and selects the corresponding base
station access point to connect;
3. The base station uses an external radio to broadcast
differential data, as shown in Figure 3.5-4. The baud rate
must be consistent with the connected external radio;
4. For CORS settings, refer to the rover data link for
corresponding conguration.

3.12 Localization
Click [Project][Localization], as shown in Figure
3.12-1, you can import control point parameters in various
formats, or export control point data into les by third-party
software. The high-precision position obtained by the
software from the GNSS device is the latitude and longitude
coordinates of satellite positioning, but in actual project
operations, the plane coordinates on the ground are
ultimately required for survey and application. If the
customer has coordinates conversion parameters, the
coordinate system parameter values can be set directly in
the coordinate system (details 2.3). If the customer does not
have specic coordinate system parameters, but has
corresponding latitude and longitude coordinates and plane
coordinates, we call them control points. In the case of
control point data, this function can be used to calculate the
conversion parameters and apply them to project
operations.
Click [Add], as shown in Figure 3.12-2, you can manually
enter the control point, or choose to import it from the
coordinate point library, as shown in Figure 3.12-3. In the
control point list, select the data item to modify, edit and
delete the control point parameters, as shown in Figure
3.12-4.

3.13 Calibrate Point
Click [Project] [Calibrate Point], as shown in Figure
3.13-1. In actual application, GNSS equipment obtains
high-precision position by combining differential data of
base station with solution. Here we know the coordinate
position of base station. In fact, the high-precision position
output by GNSS equipment is the relative position of base
station. In actual application, some users using differential
data of CORS reference station, there are also quite a few
users using differential data of base station transmitted by
their own GNSS equipment. When transmitting differential
data by building their own stations, a project may involve
starting base station multiple times. When initiating the
base station, the starting position and starting coordinates
of base station may change, and the starting coordinates
may not be correct. In the absence of calibration, the
coordinates of rover obtained by using these base station
corresponding accuracy is achieved within the accuracy
range, the calculated conversion parameters are considered
to be available. The plane correction model includes four
parameters and horizontal adjustment. The elevation tting
method includes weighted average, plane tting, surface
tting and vertical adjustment. Usually, if the operating
range is very wide, seven parameters are needed to meet
the accuracy requirements of all control points. If the
operating range is relatively small, plane correction can
usually achieve the corresponding accuracy.
After conguring the calculation conditions, click
[Calculate] to display the calculation results of the
conversion parameters and the residuals of each control
point, as shown in Figure 3.12-6. After calculating the
conversion parameters, you can export the calculation
report for project review. If the conversion parameters are
qualied, apply the parameters to the project and you can
perform the surveying work normally.
3.10 Point Stakeout
Click [Survey] [Point Stakeout] to enter the point
stakeout library interface, as shown in Figure 3.10-1. Point
stakeout means nding the location of a point through
coordinate points in the eld when the coordinates of the
point are known. Points that have not been staked out and
those have been staked out will be displayed. Click the
stakeout point to edit, view details, stake out, and delete the
stakeout point, as shown in Figure 3.10-2. The points to be
staked out are part of the coordinate point library. The
operations of adding, removing, importing, and exporting
stakeout points are the same as those in the coordinate
point library. Removing points from the points to be staked
out does not actually delete points in the point library. You
can also select points from the coordinate points (all points
in the coordinate point library) for stakeout. After selecting
points for stakeout, enter the point stakeout interface, as
shown in Figure 3.10-3.

coordinates;
Click [Import], as shown in Figure 3.14- 4, select the le
format of the point data to be imported, and then select the
data le to complete the data import.
Select the coordinate point and click [Edit], as shown in
Figure 3.14-5, you can edit and modify the name and code of
the coordinate point;
differentials may be wrong (at the same location, the
coordinates measured by previous differential data are
different from the coordinates obtained by new differential
data). Therefore, when the rover receives new base station
differential data for surveying, it needs to perform points
calibration so that the coordinates obtained by software
match the coordinates obtained by connecting to the last
base station. After the starting coordinates or starting
position of the base station changes, a known position needs
to be used to calibrate the coordinates correctly.
Click [Base Point Calibration], as shown in Figure 3.13-2,
and click to select a known point in the coordinate point
library (use the coordinates measured by the base station at
a certain location last time). Then click [Calculate] and
apply.
Click [ Marker Point Calibration], as shown in Figure
3.13-3, and click select a known point in the coordinate
point library (use the coordinates measured by the base
station at a certain location last time), then place the GNSS
device at the location of the known point. Click to measure
a new positioning point, and calculate the deviation value.
Click [Apply], and the coordinates received by the software
will match the coordinates measured last time.
The base station coordinates change and remind you
whether to recalibrate. If the base station coordinates
change when receiving the differential signal from the
self-built base station, it means that the points calibration of
base station is required and needs to be re-calibrated.
Note: The CORS reference station is a long-term
operating reference station whose position and startup
coordinates will not change. If the differential data of the
CORS reference station is used, the received coordinates
may change, the obtained coordinates are still correct and
no translation calibration is required.
Click the icon to enter the layout setting interface,
as shown in Figure 3.10-4, where you can set the prompt
range, layout tolerance, etc. You can also set the reference
