CUAV C-RTK Positioning Module 9P | High Precision GPS RTK for Pixhawk

C-RTK 9P Positioning Module C-RTK 9P is a centimeter-level RTK module. Using two C-RTK 9P modules, one installed on the base and the other installed on the UAV, a real-time RTK system is designed. Compatible with open-source autopilots like PX4 or Ardupilot, this RTK module is an ideal choice for aerial performance and agricultural applications. You can have high-precision take-off, landing, and missions. A ublox F9P module is used inside to support multiple frequencies as well as the reception from different satellite systems — GPS/QZSS, Beidou, Glonass, Galileo. Due to using multiple satellites and multiple frequencies, and with the help of advanced RTK algorithms, the position of the base station converges and provides centimeter-level differential data in less than half a minute. The update rate of the RTK algorithm is at 20Hz. The base and rover units are the same modules with different configuration parameters and different antennas. That just makes it easy to use them in place of each other by just changing a few parameters. The modules are only 21g, and can work in harsh environments and temperatures from –40°C to +85°C.

What is the C-RTK 9P used for? It is a high-precision RTK GNSS (satellite navigation) module designed to provide centimetre-level positioning accuracy for UAVs and other unmanned systems. 2. What measurement accuracy and satellite capabilities does it support? It delivers RTK precision of approximately 0.01 m + 1 ppm (horizontal) and supports multiple GNSS constellations (GPS, GLONASS, Galileo, BeiDou) across multiple frequency bands. 3. What are some of its key hardware and interface specifications? It uses a u-blox ZED-F9P receiver, includes built-in anti-jamming and anti-spoofing features, has update rates up to ~20 Hz in RTK mode, and communicates via UART/USB/I²C interfaces. 4. What are the power, size, environmental and operational specs? It operates on ~4.5-6 V input, supports temperatures from about -40 °C to +85 °C, and its module size is roughly 31.5 × 48 × 12 mm with a weight of ~21 g. 5. What installation or usage considerations should be followed? To get optimal performance you must mount the antenna with a clear view of the sky, minimize obstructions / multipath, and for yaw/heading applications you may use two of these modules spaced apart to replace a magnetic compass in high-interference environments. 6. Is this module suitable for professional or industrial UAV deployments? Yes — because of its high-precision GNSS performance, multi-band/multi-constellation support, industrial-grade specs and compatibility with open-source autopilots, it is well suited for advanced aerial survey, inspection, mapping or other industrial UAV applications.
