After the SMART antenna is installed and powered on, determine whether it is
in a normal working status through the LED indicator. When the power is just
turned on, the LED indicator blinks red and green alternatively, and then the
indicator is steady on red, indicating that the power supply is normal. After
a period of time, the LED indicator is steady on green (a little yellow),
indicating that the satellite signal receiving is normal.
3. HX-TS122 Operation Instructions
Before operating the receiver for the first time, see Chapter 2 “Assembly and Installation” for HX-TS122 installation instructions.
3.1 Receiver Communication
The receiver can communicate with the data terminal or computer in the
following ways:
● Bluetooth
● Serial port
After you connect the data terminal or computer to the receiver, you can enter commands directly on the terminal or using the terminal simulation software on the computer. For example:
HX-TS122 Configuration Tool is a software application used to debug and configure the HX-TS122 receiver. For more information about the HX-TS122 Configuration Tool, see the Help provided by the application.
3.1.1 Bluetooth Communication
By default, the receiver that supports the Bluetooth function adopts Classic
Bluetooth V2.0.
You can use a laptop computer, tablet computer, or smartphone that supports the Bluetooth function to search for the Bluetooth device of HX-TS122 receiver and establish a Bluetooth connection.
After the connection is established, read and configure the receiver parameters using the app configuration tool provided by the Android system.
In addition, Bluetooth can be used as a data communication interface to implement data communication between the terminal and the receiver. You can configure the Bluetooth port of the receiver as the output port of positioning information, and enable the function by configuring the command $CFG ROVER OUTPORT BT\r\n.
3.1.2 Serial Communication
The receiver can communicate with a computer or terminal through a serial
port. In order to communicate with each other, both the receiver and the
operating interface must have the same serial port configuration. The default
port configuration of the receiver is as follows:
115200 bps
No parity
8 data bits
1 stop bit
The communication baud rate of serial port 1 and serial port 2 can be modified by the configuration commands $CFG HOST BAUD Rate\r\n and $CFG EXTERN Rate\r\n respectively. The baud rate can be set to 9600, 19200, 38400, 57600, and 115200.
Serial port 1 and serial port 2 can be used for reading and setting received parameters. They can also be used for outputting positioning information, with the command $CFG ROVER OUTPORT COM1\r\n or $CFG ROVER OUTPORT COM2\r\n.
3.2 Startup
HX-TS122 receiver can save and record the parameters configured last time, and
output its basic information through serial port 1 according to the saved
information after it is powered on. After parameters are configured, some
parameter updates may not take effect immediately, and they will only take
effect after you run the $CFG DEBUG QUIT\r\n configuration command.
3.2.1 Communication with the Receiver
The communication between the HX-TS122 receiver and the user can be
implemented through two serial ports and the Bluetooth port. The above ports
can be configured to respond to configuration commands. For specific commands,
see the product command manual.
3.3 Terrain Compensation
When the ground is not flat, the receiver will have a tilt. When there is a
tilt, the coordinates measured by the SMART antenna are different from the
actual ground coordinates, resulting in an error in the measurement. Terrain
compensation can correct the ground coordinate error caused by the tilt. By
tracking the change of the 3D attitude angle (pitch, roll, and yaw) measured
by the sensor on the SMART antenna and using the height of the SMART antenna
from the ground, the system can obtain the ground coordinates and adaptively
make compensation to the ground coordinates to eliminate the problem of
trajectory offset in complex terrain movement.
Procedure for terrain compensation
-
Install the SMART antenna at a flat place.
-
Measure the height of the SMART antenna from the ground and configure the height to the SMART antenna.
For example, if the measured height is 2.0 meters, run the $CFG TERRAIN HEIGHT 2.0\r\n command to configure the height. If the antenna returns OK, the configuration is successful. -
Implement horizontal calibration.
Run the $CFG IMU TILTZERO\r\n command to implement horizontal calibration. If the antenna returns OK, the configuration is successful.
The following information provides location information for terrain compensation:
● GGA
Figure 7 SMART antenna height measurement
3.4 Slide Technology
The slide technology integrates the IMU to predict the positioning location
and adaptively filters and smoothens the predicted location and the measured
position. When the satellite signals are interrupted, the system can still
output correct location coordinates to avoid the issue of discontinuous motion
trajectory coordinates due to signal interruption. In addition, adaptive
filtering reduces positioning errors, smoothens trajectories, and further
improves relative positioning accuracy, which is suitable for pass-to-pass
applications.
The slide function is configured as follows:
Run the $CFG SLIDE ON\r\n or $CFG SLIDE OFF\r\n command to enable or disable
the slide function.
3.5 Enabling the SBAS Positioning
HX-TS122 receiver can receive multiple SBAS signals simultaneously, even from
different SBAS systems (such as WAAS, EGNOS, and MSAS). Run the $CFG GNSS SBAS
ON\r\n or $CFG GNSS SBAS OFF\r\n command to enable or disable the SBAS
positioning function.
