Grindel F9P-RTK module, integrated high-precision board (ZED-F9P) can receive GPS, Beidou, GALILEO, GLONASS satellite system L1, L2 frequency points at the same time, combined with high-precision antenna integrated design, small size, light weight, Only need an external 5V power supply and an external NTRIP DTU network differential radio station to quickly complete RTK high-precision centimeter-level positioning. Through the configuration software, you can configure the ZED-F9P to connect to the Chihiro service, CORS station and self-built station to easily build a network RTK high-precision positioning system. Widely used in high-precision driving test, unmanned patrol car, unmanned logistics robot, drone formation flying base station, automatic driving test, high-precision slope monitoring, smart port, smart agriculture, high-precision data collection, high-precision navigation High-precision positioning applications such as positioning.
The following will introduce how ublox ZED-F9P is configured and combined with NTRIP DTU network differential radio to connect to the Chihiro service/self-built station to achieve high-precision network RTK positioning.
Preparation stage
1. ublox ZED-F9P module
2. RS232 serial port module
3. U-center configuration software
4. Grinding NTRIP DTU Internet radio
5. Qianxun account (need to purchase from Qianxun)
(1) Configure ublox ZED-F9P as a mobile station,
connect RS232 to ublox ZED-F9P module serial port 1, open the U-Center configuration software,
| Serial number | Instructions |
|---|---|
| 1 | Select the corresponding serial port, open the serial port |
| 2 | Select the baud rate, the module defaults to 38400 |
Continue configuration
| Serial number | Instructions |
|---|---|
| 3 | Open the toolbar View option, select Message View |
| 4 | Select UBX-CFG-PRT on the leftmost side of the pop-up interface, click PRT option |
| 5 | In the pop-up box on the right, Target selects UART2 and configures the serial port 2 of the module |
| 6 | In the right pop-up box, select 5-RTCM3 in Protocol in, enter RTCM3 protocol data |
| 7 | In the right box, the baud rate is 115200 (user can set it, it needs to be consistent with NTRIP DTU output baud rate) |
| 8 | Select Send, sending is complete |
Continue configuration
| Serial number | Instructions |
|---|---|
| 9 | Continue in UBX-CFG, select CFG |
| 10 | Select the save parameter option |
| 11 | Select send, the sending is completed, the mobile station is set successfully |
(2) Configure Grindel NTRIP DTU Internet radio to connect to Chihiro
| Serial number | Instructions |
|---|---|
| 1 | Select the serial port communication baud rate, set 115200, consistent with the F9P setting |
| 2 | Enter the IP address of Chihiro website 203.107.45.154 |
| 3 | Fill in the port number assigned by Chihiro |
| 4 | Fill in the mount point |
| 5 | Fill in the Qianxun account |
| 6 | Fill in the password |
| 7 | Save the parameters, NTRIP DTU setting is complete |
Remarks: It can be connected to Qianxun, or to the service platform built by Grindel.
(3) The actual connection diagram
configures ZED-F9P and NTRIP DTU, after which, connect NTRIP DTU serial port 2 to ZED-F9P serial port 2, The connection diagram is as follows:
After the correct connection, there is an indicator light indicating that the green light indicates that the DTU is working normally, the yellow light flashes quickly to indicate that it is connected to the Qianxun server, and the red light indicates that the power supply is normal.
The RTK indicator of ZED-F9P, the green light is always on, it means the solution has been fixed, and the green light flashes slowly, it means the floating solution. The network RTK positioning effect is as follows:
