Did you know… with the LR kit you can connect to the base station and see real time the rover’s position?

With our simpleRTK2B – Starter Kit LR IP67, you will receive a pre-configured base and a pre-configured rover.
Would you like to be connected with your PC to the base station, and in addition of seeing the base position, also see real time the rover’s position? It’s possible! Just follow this guide, it’s only 2 steps:
1. Take your rover, connect to POWER+GPS USB port, and load the configuration file “srtk2b_rover_sends_back_GGA_to_base_FW_HPG112.txt” from our Configuration Files page.
2. Now go to your base:
- If you connect to POWER+GPS USB port, you will see, as before, the position of the base station.
- But if you now connect to the POWER+XBEE USB port, you will see the position of the rover, real time! And for your Arduino project, you also have the rover’s position available in the TX2,RX2 pins of your base station simpleRTK2B!
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 tradeoff between lenght, content and easy to read.
Important note: This configuration only works with rover working at 1Hz. If you then increase the rover navigation rate, make sure you reduce the GGA send rate (UBX-MSG-CFG) with the same amount, so it’s only sent once per second.
