Introduction
The Leica GS18 T is a high-precision GNSS RTK rover that integrates GNSS and Inertial Measurement Unit (IMU) technology. This allows for automatic pole tilt compensation, enhancing productivity and user experience in surveying tasks.
Key Advantages
- IMU-based tilt compensation: Immune to magnetic disturbances and free from on-site calibrations.
- Increased productivity: Eliminates the need for manual pole levelling, saving time.
- Enhanced applicability: Enables measurements at large tilt angles and in challenging environments like urban canyons or near buildings.
- Advanced signal tracking: Robust performance even with low-elevation satellites and multipath interference.
- Heading-aided 3D visualization: Improves user orientation and navigation in the field.
- Traceable measurements: Attitude information is stored for quality assurance.
Technology Overview
The GS18 T utilizes a customized Inertial Navigation System (INS) integrated with GNSS. This IMU-based approach offers superior accuracy and reliability compared to traditional magnetometer-based tilt compensation systems, especially in environments with magnetic interference.
Advanced antenna design and a high-performance measurement engine ensure reliable tracking of multiple satellite constellations and correction signals, even under difficult conditions.
Performance and Reliability
Test results demonstrate significant improvements in productivity (up to 33% more points measured) and accuracy, particularly in challenging environments with multipath interference or when measuring obstructed points.
The system maintains high accuracy and reliability even at large tilt angles (over 30 degrees), offering a robust solution for demanding surveying tasks.
