Description

The C-RTK 9Ps is engineered around the u-blox ZED-F9P module, providing robust 184-channel reception across GPS, GLONASS, Galileo, and BeiDou constellations on multiple frequency bands. This multi-star, multi-frequency architecture ensures reliable satellite acquisition and maintains high-precision positioning even in challenging environments. The module’s dual RTK capability allows one unit to function as a rover on the aircraft while another serves as a ground base station, enabling real-time kinematic corrections.

Its design specifically supports using dual GPS/RTK modules for yaw heading determination, effectively replacing the UAV’s magnetic compass. This makes the system immune to local magnetic interference, a critical advantage for operations near power lines, steel structures, or in agricultural settings. The C-RTK 9Ps achieves performance comparable to higher-cost units through an efficient dual-end switchover architecture, offering a high-value solution for precision navigation applications.

Frequently Asked Questions

What is the difference between the C-RTK 9Ps and the C-RTK 9P?

The C-RTK 9Ps utilizes a dual-end switchover design to achieve similar centimeter-level RTK performance as the C-RTK 9P but at a reduced cost. It maintains core functionality, including multi-constellation support and dual-module yaw calculation, making it a more cost-effective solution for high-precision applications.

How does the dual RTK for yaw feature work?

By using two C-RTK 9Ps modules—one as a rover on the drone and one as a base station—the system calculates the vehicle's yaw (heading) from the relative position between the two GPS antennas. This eliminates reliance on a magnetic compass, making the UAV immune to local magnetic interference from motors, wiring, or ferrous structures.

What flight controllers is the C-RTK 9Ps compatible with?

The module is fully compatible with open-source flight controllers running PX4 or ArduPilot firmware, such as Pixhawk-series autopilots. It communicates via UART using standard NMEA, UBX, and RTCM protocols for seamless integration into automated navigation stacks.

What power supply does the C-RTK 9Ps require?

The module operates on a voltage range of 4.5V to 6V, making it directly compatible with standard 5V regulated power sources commonly available on drone power distribution boards or flight controller BEC outputs.
