Data collected from the primary and secondary antennas are transmitted to two separate processors, allowing for independent computation of Real-Time Kinematic (RTK) positioning, thereby enhancing the overall robustness of the system.
• Full-constellation & Multi-frequency
The K827 integrates Global Navigation Satellite System (GNSS) technology with Inertial Measurement Unit (IMU) capabilities to provide accurate positioning even in difficult environments. It is capable of maintaining centimeter-level accuracy for a duration of 3 seconds and meter-level accuracy for up to 10 seconds during periods of signal loss.
• Strong Compatibility
K827 is designed to be compatible with widely used GNSS boards, accommodating both physical and data formats. This ensures a smooth transition for customers utilizing boards that conform to the global standard of 20 to 28 pins.
