Leica GS18 tilt‑compensated GNSS antenna with IMU, offering calibration‑free, magnetic‑interference‑immune measurements.
The Leica GS18 tilt machine combines a high‑precision inertial measurement unit (IMU) with a GNSS antenna to provide automatic tilt compensation without any calibration. It works in challenging environments such as urban sites, power‑line corridors, and remote offshore locations, delivering fast, accurate positioning even under strong electromagnetic interference.
Key features include 555‑channel multi‑constellation tracking, SmartLink satellite‑based augmentation for global 24‑hour centimeter‑level accuracy, an integrated 4G LTE communications module, and rugged IP68 protection. The system is supported by Leica Infinity software and the Leica Smartlink app for seamless data processing and reporting. This manual is written in Chinese.

No, the GS18 provides automatic tilt compensation and does not need any calibration.
It can track up to 555 channels covering all major GNSS constellations.
No, its IMU‑based tilt compensation makes it immune to magnetic field interference.
