This feature not only speeds up workflows but also makes it easier to capture points that are otherwise hard to access, increasing overall productivity.
    • The tilt compensation is calibration-free and immune to magnetic interference, ensuring that measurements remain accurate even in proximity to metallic structures.
  2. Comprehensive GNSS Compatibility
    • The Leica GS18 T supports GPS, GLONASS, Galileo, BeiDou, QZSS, and NavIC, providing global coverage and the ability to work in any location. This multi-frequency RTK GNSS system enables quick fixes and reliable accuracy under diverse conditions, making it an exceptional GNSS RTK rover.
    • With 555 channels, the GS18 T provides robust signal tracking and high sensitivity, ensuring stable and precise data collection.
  3. Leica Captivate Integration
    • Paired with Leica Captivate field software, the GS18 T offers an intuitive interface for managing GNSS RTK data, enhancing the workflow for applications like topographic mapping, construction layout, and boundary surveys. Leica Captivate simplifies data collection and analysis, providing a streamlined experience for surveyors.
  4. Reliable Real-Time Communication
    • Equipped with 4G LTE, UHF, Bluetooth, and WLAN capabilities, the Leica GS18 T offers seamless communication for real-time RTK corrections. This makes it compatible with Network RTK, DGPS/RTCM, and other communication protocols, ensuring fast, accurate, and consistent measurements.
    • The rover also supports RTK bridging, allowing up to 10 minutes of continuous operation in the event of RTK signal loss, ideal for remote or signal-challenged environments.
  5. Robust and Durable for Field Use
    • With an IP68 rating, the GS18 T is dust- and water-resistant, built to withstand the demands of fieldwork in harsh environments. Operating in temperatures as low as -40°C and as high as +65°C, this Leica RTK rover ensures durability and reliability for extended projects.
    • Designed for portability, the Leica GS18 T is compact and lightweight at just 1.23 kg, making it easy to carry and deploy in various locations.
