Precis RTK board can be integrated with autopilots. We use the connection to Pixhawk flight control as an example. A cable is used to connect the COM1 port of Precis RTK board and the GPS port of the Pixhawk (see Figure 1). It is noticed that the GPS port need a 6pin PicoBlade connector while the COM1 port is a 5pin PicoBlade connector. The pin definition of the Pixhawk GPS port is listed in Table 1. With regarding to the power consumption, we recommend using external power sources. Please also pay attention to the baud rate setting of Pixhawk. Then you need to mount the GNSS antenna and tether the board on your vehicle.
Please beware of following instructions when you mount the GNSS antenna to your drone.
■ Place the module on the outside of your vehicle (in an elevated position if appropriate) with a clear view of the sky
■ Distance the module from DC power wiring and the batteries by at least 10cm
Next step is setting up the Pixhawk with mission planner. Open Mission planner software and choose the right COM port on the top right corner. Choose 115200 as baud rate (default baud rate of Precis RTK board COM1 port). Then click ‘connect button’ on the right. Then it is recognized by mission planner if the GPS status becomes ‘3D Fix’ (see Figure 2).
