Auto conf (QGControl / MP)

The RTK modules can easily be configured automatically using the QGroundControl or Mission Planner softwares, which will set up your module as you want without having to go deep into the configuration processes for the U-blox chip.

QGroundControl

In order to configure the base, you will need:

• 1 Computer, used as ground control station

• 1 Micro USB cable

• Latest version of QGroundControl Software (available here)

PX4 advise to use the MAVLink 2 protocol within your telemetry link in order to use the channel efficiently. It should be the default parameter, but if it isn't, you will find out how to toggle it at the bottom of this page.

Begin with plugging your base module through USB to the computer with QGroundControl installed and open. The module should be recognized automatically.

Keep in mind that the base must be installed in an accessible place, have an unobstructed view of the sky and be the most stable possible.

The software will initiate the Survey-in procedure with default parameters. You should see the monitoring box next to the top hotbar, giving details on the surveying time, current accuracy and satellites the base is connected with.

You can set the values for the surveying time and a minimum accuracy in the general settings menu of the QGroundControl software, it's button located on the top left corner of the main window.

Once the survey-in procedure is complete, the satellites icon in the top hotbar will turn white, and the base module will start sending data to the rover module (if it is set up) through the telemetry link. The RTK will be active and ready to use as soon as the rover module will have been set up!

Mission Planner

In order to configure the base, you need:

• 1 Computer, used as ground control station

• 1 Micro USB cable

• Latest version of Missiono Planner Software (available here)

First, connect your base module to the computer with Mission Planner installed. Open the software, and click the Initial Setup button on the top hotbar. In the left panel, click the Optional Hardware section, and open the RTK/GPS Inject menu.

You have reached the RTK configuration page. Begin with connecting to your base module, by selecting the COM port corresponding to it, and clicking Connect. You won't need to change the baudrate as the connection is using USB protocol, but if necessary, enter 57600.

Once connected, you'll be provided with informations on the behavior of your base module. After checking the M8P Autoconfig box, you will need to use the survey-in method in order to obtain a location for your base. You can set the necessary accuracy and minimum survey-in time in order to get a position for your base. After setting your own parameters, you can click Restart to operate a new survey-in that will store it's obtained position in the list beneath the parameters box.

Mission Planner allows the user to store and use previous locations for your base setup. You will find all useful information on this page.

From now on, your base is set up, and only requires you to set up your rover module!
