How to connect to the Base station and see the Rover’s position in real time with the Base+Rover Kit
Would you like to be connected with your PC to the Base station, and in addition of seeing the Base´s position, also see real time the Rover’s position?
In this tutorial we will show you step by step how to do it.
Required hardware:
Required software:
- u-center (for F9 / M9 products)
How to connect to the Base station and see the Rover’s position in real time?
Firstly, configure your Rover.
- Connect your Rover receiver to your PC with the USB port labeled as POWER+GPS.
- Open u-center. Connect your receiver to u-center via COM port.
- Download the configuration file named as “Rover 1Hz with 4G NTRIP Client (sending NMEA-GGA)” from our Configuration Files page. Upload it to your Rover. Make sure you download the configuration file compatible with the firmware version of your receiver .
If you don´t know how to do this, have a look at this tutorial.
Secondly, now go to your Base.
- Connect the GNSS antennas to both your Base and Rover receivers. Place the antennas in a location with good view of the sky, or near a window for testing the functionality
- If you connect your Base through the USB port labeled as POWER+GPS, you will see the position of the Base station as before.
- Connect your Base receiver through the USB port labeled as POWER+XBEE.
- Connect your Base receiver with u-center. Set baudrate to 115’200. You will see the position of your rover.
- If you have an Arduino project, you will have the Rover’s position available in the TX2, RX2 pins of your Base station of simpleRTK2B series boards!
- You will notice that only the position and fix status information is available, and there’s no information about satellite data. This is because the radio link has a limited bandwidth and we can only transmit one message from the base to the rover. We selected the GGA message which is a good trade-off between length and content. Moreover it is easy to read.
- Important note: This configuration only works with Rover working at 1Hz. If you want to increase the Rover navigation rate, make sure you reduce the GGA sening rate (UBX–>CFG–>MSG) with the same amount, so it’s only sent once per second.
Now you can track the location of your Rover on your Base in real time!
