K827N GNSS Board
The K827N GNSS board is designed to monitor all existing and future GNSS constellations, accommodating both L-Band and S-Band signal types. It incorporates advanced Dual-Engine RTK technology, which provides centimeter-level positioning accuracy and precise heading information in both stationary and moving scenarios. With standard dimensions of 46mm × 71mm × 10mm, it can be seamlessly integrated into a wide range of systems. This board is particularly well-suited for applications including land surveying, autonomous vehicle navigation, precision agriculture, machine control, robotics, and unmanned aerial vehicles (UAVs).

The integration of Dual-Engine RTK technology allows for the transmission of data from both the primary and secondary antennas to two separate processors, where the RTK calculations are performed independently. This approach enhances the system's robustness and increases positioning availability, particularly in challenging environments.
• Full-constellation & Multi-frequency
K827N integrates Global Navigation Satellite System (GNSS) and Inertial Measurement Unit (IMU) technologies to provide accurate positioning in difficult environments, including urban canyons, beneath tree canopies, or under bridges. In instances where the GNSS signal is lost, it is capable of maintaining centimeter-level accuracy for up to 3 seconds and meter-level accuracy for up to 10 seconds.
• Strong Compatibility
The K827N has been engineered with standardized input/output and pin configurations, making it compatible with widely used GNSS boards across both physical and data formats. This design guarantees a smooth transition for customers utilizing boards that conform to the global standard of 20 to 28 pins.
