Thank you for purchasing SIYI product.

SIYI F9P RTK User Manual v1.0

F9P RTK module is a high-accuracy centimeter-level four-satellite multi- frequency navigation and position system developed for autopilot systems. Through real-time kinematic position technology, the 3D position accuracy is improved from meter level to centimeter level. It integrates position, altitude detection and dual-module direction finding functions. RTK technology makes up for the shortcomings of traditional GPS, barometer, and magnetic compass, enables UAVs to adapt to complex magnetic field environments, and provides accurate and reliable systematic solutions for high-accuracy applications.

To ensure you a good experience of the product, please read this manual carefully. If you encounter any issue using the product, please consult the manual or check the online pages of this product on SIYI official website (https://siyi.biz/en). You can also write an email to SIYI official A/S center (support@siyi.biz).

Negative means the antenna is on the back side of the flight controller. GPS_POS1_Z = The distance between GPS1 antenna’s Z axis and flight controller: Positive means the antenna is on the upside of the flight controller. Negative means the antenna is on the downside of the flight controller. GPS_POS2_Y = The distance between GPS1 antenna’s Y axis and flight controller: Positive means the antenna is on the right side of the flight controller. Negative means the antenna is on the left side of the flight controller. GPS_POS2_X = The distance between GPS1 antenna’s X axis and flight controller: Positive means the antenna is on the front side of the flight controller. Negative means the antenna is on the back side of the flight controller. GPS_POS2_Z = The distance between GPS1 antenna’s Z axis and flight controller: Positive means the antenna is on the upside of the flight controller. Negative means the antenna is on the downside of the flight controller.
Mark The horizontal distance between GPS1 antenna and GPS2 antenna must be at least 30 cm to guarantee the direction-finding accuracy. The RTK mobile module connected to SERIAL3 port is GPS1 in default. The RTK mobile module connected to SERIAL4 port is GPS2 in default.

Confirm Dual Module Direction Finding

SIYI F9P RTK User Manual v1.0

Run Mission Planner GCS, check if the orientation of “GPS_YAW” aligns with the

actual orientation. If yes, dual module direction finding configuration is successful.

If not, “GPS_POS” configuration is wrong.

GCS messages say “EKF3 IMUx yaw aligned”, dual module direction-finding is successful.
