Bid Farewell to the Compass: Flawless GNSS-Based Heading Determination
The SIYI RTK Positioning and Heading Module calculates not only your precise location but also the exact direction your vehicle is facing (heading) with millimeter accuracy. Thanks to Dual-Antenna technology, heading information is derived from the phase difference between two antennas instead of a magnetic compass. This feature completely prevents the drone from deviating from its course in environments that interfere with a compass, such as high-voltage power lines, mining sites, or ship decks.
Key Technical Specifications
-
Centimeter-Level RTK Accuracy: Achieves 1cm + 1ppm horizontal positioning accuracy when operating with an RTK ground station. Guarantees the highest accuracy for mapping and autonomous missions.
-
Immunity to Magnetic Interference: Unlike traditional magnetometers (compasses), it is not affected by magnetic fields. Offers unwavering stability in industrial areas with high electromagnetic noise.
-
Multi-Constellation and Dual-Frequency: Simultaneously tracks GPS, GLONASS, Galileo, and BeiDou systems. With dual-frequency support, it achieves an RTK fixed solution in seconds, even in "urban canyon" environments with buildings or obstacles.
-
High Update Rate: With a data refresh rate of up to 20Hz, it transmits the real-time position of high-speed UAVs and autonomously maneuvering vehicles to the flight controller.
-
Full Integration with SIYI Ecosystem: Plug-and-play compatible with SIYI MK15, HM30, and FM30 systems. It also communicates with Pixhawk (V6X, Cube Orange) based autopilots via standard protocols.
