The SIYI F9P RTK Combo is a high-precision RTK GNSS solution designed for professional UAVs, autonomous drones, and robotic platforms. Available in both Base Station Combo and Mobile Station Combo versions, it provides centimeter-level positioning accuracy for demanding navigation, mapping, surveying, inspection, and precision agriculture applications.
Built around the SIYI F9P RTK module, the system supports multi-frequency GNSS positioning, fast RTK convergence, and reliable integration with professional autopilot systems.
High-Precision RTK Positioning
The SIYI F9P RTK system provides centimeter-level positioning accuracy.
With RTK technology, it improves 3D positioning accuracy from meter level to centimeter level, making it suitable for professional UAV operations requiring precise navigation and reliable positioning.
Available in Base Station & Mobile Station Versions
The SIYI F9P RTK is available in two combo versions depending on the application.
The Base Station Combo is designed to provide RTK correction data from the ground station setup.
The Mobile Station Combo is designed to be installed on the UAV, receiving correction data for accurate aircraft-side positioning.
Base Station Combo
The Base Station Combo includes the F9P RTK base module, a high-gain mushroom head RTK antenna, antenna cable, and USB-C cable.
It is designed for fixed ground station use and provides correction data to the mobile RTK unit through the flight controller and datalink system.
The base station antenna offers 5.5 dBi gain for strong signal reception and reliable RTK correction workflows.
Mobile Station Combo
The Mobile Station Combo includes the F9P RTK mobile module, four-arm spiral antenna, antenna bracket, and connection cables for autopilot integration.
It is designed for aircraft-side installation and provides high-precision positioning data during UAV operation.
The mobile antenna offers 2 dBi gain and is optimized for UAV mounting and RTK rover applications.
Dual-Module Direction Finding
The SIYI F9P RTK system supports dual-module direction finding when using two mobile station modules.
This allows heading information to be generated through RTK positioning, helping replace compass-based heading in complex magnetic environments.
Fast RTK Convergence
The system supports fast RTK positioning, with RTK survey time under 55 seconds.
GPS acquisition is also fast, with cold start under 23 seconds and hot start under 1 second, helping reduce setup time during field operations.
Flexible Connectivity
The SIYI F9P RTK module includes 2 UART interfaces and 1 USB Type-C port.
The antenna connection uses an MMCX interface, allowing connection to the included base station or mobile station antenna depending on the selected combo.
Professional UAV Applications
The SIYI F9P RTK Combo is suitable for UAV mapping, surveying, precision agriculture, inspection, autonomous navigation, and professional drone operations.
It is designed to work with compatible autopilot systems and professional UAV platforms requiring high-accuracy RTK positioning.
