Centimeter-Level RTK Accuracy
High-Precision GNSS Engine
At the core of this system is a powerful 1408-channel GNSS engine that supports multiple satellite constellations. This ensures reliable positioning even in environments where signal interference is common.
The ability to track GPS, GLONASS, Galileo, BDS, QZSS, and SBAS provides global coverage and enhances accuracy. This multi-constellation support is crucial for maintaining consistent performance in both urban and remote locations.
Fast Initialization
The system achieves initialization in approximately five seconds, allowing users to begin work almost immediately. This reduces downtime and improves productivity, especially in time-sensitive projects.
Reliable Performance in Challenging Environments
One of the standout features is its ability to maintain centimeter-level accuracy under trees and in urban canyons. This makes it suitable for a wide range of applications, from dense forests to city construction sites.
Augmented Reality Stakeout Technology
Visual Guidance for Faster Layout
The AR stakeout feature is one of the most innovative aspects of the L1-AR system. It overlays virtual points directly onto the real-world camera view, providing intuitive guidance for field layout.
This eliminates the need for complex calculations and manual interpretation, allowing users to position points quickly and accurately.
Enhanced Workflow Efficiency
By combining AR visualization with GNSS data, the system streamlines the stakeout process. Users can see exactly where to place points, reducing errors and improving efficiency.
Integration with Handheld Collectors
The AR functionality is also supported by handheld collectors, providing flexibility and ensuring that users can adapt the system to their preferred workflow.
Camera and Visual Capabilities
2 MP Starlight Camera
The integrated 2 MP starlight camera enhances the AR experience by providing clear visuals even in low-light conditions. This ensures that users can continue working effectively during early mornings, late evenings, or in shaded environments.
Wide Field of View
With a 75-degree field of view, the camera captures a broad perspective, making it easier to align virtual points with real-world objects.
Improved Accuracy with Visual Feedback
The bottom camera ensures precise positioning as users approach target points. This visual feedback reduces the margin of error and enhances overall accuracy.
CAD Integration and Workflow Simplification
Seamless CAD Compatibility
The L1-AR system supports DWG and DXF file formats, allowing users to integrate CAD drawings directly into their workflow. This feature bridges the gap between design and execution.
Real-Time Visualization
By overlaying CAD data onto the real-world environment, users can visualize project layouts in real time. This improves decision-making and reduces the likelihood of errors.
Faster Project Completion
The ability to work directly with CAD files eliminates the need for manual data conversion, saving time and simplifying the workflow.
Tilt Compensation and IMU Technology
Advanced Tilt Compensation
The system features a high-grade IMU that supports tilt compensation of up to ±60 degrees. This allows users to take accurate measurements without needing to keep the pole perfectly vertical.
Increased Efficiency in Fieldwork
Tilt compensation significantly speeds up the surveying process, as users can capture points more quickly without adjusting their position constantly.
High Accuracy at Maximum Tilt
Even at maximum tilt, the system maintains an accuracy of up to 2 centimeters. This ensures reliable results in all conditions.
