Deploy! You're ready to start testing with RTK. Head out into the world.

It’s time to go into the field. If you’ve configured your modules and saved the settings to BBR/Flash they should be able to be powered up and autonomously begin the RTK link. Once the base has completed its survey-in process it should begin transmitting RTCM over the radio link. After receiving only a few seconds worth of RTCM over the radio link the rover's ZED-F9P receiver should enter RTK Float, then RTK Fix, and begin outputting high accuracy positional data. You also have the option of using a microcontroller on one or both receivers to tailor the configuration based on conditions, location, etc. The microcontroller, in conjunction with the SparkFun u-blox GNSS Arduino Library can configure the module for custom setups in the field.

We recommend experimenting with the basic radio-linked RTK setup to get used to the process. In our next tutorial we will show you how to use NTRIP to connect a rover to your correction data over a cellular link.
