Unicore has introduced the UM981 series, a high-precision positioning module that integrates RTK and inertial navigation system (INS) technologies. The solution leverages GNSS and INS navigation to cater to applications in precision agriculture, surveying and mapping.
<p>The module is compatible with all major navigation systems and frequencies, tracking signals from multiple systems simultaneously for enhanced performance even in challenging environments. Additionally, the UM981 series supports open Precise Point Positioning (PPP) services such as BDS-3 PPP-B2b, Galileo E6 HAS and QZSS L6 MADOCA-PPP, achieving 10 cm positioning accuracy with a convergence time of under 10 minutes, according to Unicore. </p> <p>The UM981 series processes high-frequency GNSS and IMU data streams efficiently, offering RTCM data transmission at up to 20 Hz, single-point positioning and RTK at up to 50 Hz and integrated navigation data and IMU raw data at up to 100 Hz. These capabilities make it suitable for dynamic scenarios requiring high precision.</p> <p>In precision agriculture, the UM981 module simplifies machinery auto-steering systems by enabling single-antenna positioning and attitude determination through advanced MEMS technology. At speeds above 1 km/h, it achieves heading accuracy better than 0.3° and roll/pitch measurements better than 0.2°, with accuracy improving as speed increases. The module supports CAN Bus communication and can be customized to work with the ISOBUS Protocol, eliminating the need for switching between interfaces during serial port communication. </p> <p>For surveying and mapping applications, the UM981S variant delivers high-accuracy positioning and tilt measurement using GNSS and INS fusion algorithms. It eliminates traditional shake-to-start requirements with a walk-and-go feature that allows users to initialize tilt measurement simply by walking with the measurement pole. The module provides 2.5 cm accuracy within a 30° tilt range and supports measurements at larger angles up to 120°, making it suitable for complex environments such as building corners or areas under tree canopies.</p> <p></p> <p><p>The post <a target="_blank" rel="nofollow" href="https://www.gpsworld.com/new-unicore-module-advances-precision-ag-surveying-and-mapping/">New Unicore module advances precision ag, surveying and mapping</a> first appeared on <a target="_blank" rel="nofollow" href="https://www.gpsworld.com">GPS World</a>.</p></p>
