KDR732E-RTK/P

The KDR732E-RTK/P is a professional-grade GNSS positioning module that employs RTK (Real-Time Kinematic) technology to achieve centimeter-level positioning. Engineers report stable horizontal positioning accuracy within 2cm in open areas. This module supports joint positioning across four systems: GPS, GLONASS, Galileo, and BeiDou, significantly improving reliability and availability in complex environments.

Internally, it integrates a high-performance ceramic antenna and RF front-end, making it particularly suitable for mobile platforms such as drones, agricultural machinery, and surveying equipment. The core of the module consists of a multi-band GNSS receiver chip, RF front-end, ARM processor, and RTK algorithm unit. Its operation involves receiving satellite signals and simultaneously acquiring differential correction data from nearby base stations.

Key features include a horizontal positioning accuracy of 1cm + 1ppm, maintaining stability within 2cm over a 10km baseline. The data update rate can reach up to 20Hz, catering to high-speed mobile platforms. It incorporates an anti-interference design with adaptive filtering to suppress radio frequency interference. Power consumption is kept below 1.5W, and it supports a wide voltage input range of 9-36V, suitable for vehicle-mounted and battery-powered applications. The operating temperature range is -40℃ to 85℃, allowing it to function in harsh environments.

Primary application areas include precision agriculture for navigation in autonomous tractors, variable rate fertilizer applicators, and harvesters, ensuring inter-row operation deviations do not exceed 3cm. In surveying, it is used for mobile mapping systems and construction layout, offering over 5 times the efficiency of traditional total stations. For drones, it is applied in aerial surveying and power line inspection, enabling centimeter-level flight path control when paired with a gimbal.
