Main Features:

Dual-axis Compensation

The GTS-320/R is configured with advanced dual-axis compensator for auto error elimination and auto accuracy compensation.

Absolute Encoding

The absolute encoding disk ensures high accuracy, efficiency and stable performance. Intialization is needless but to measure the angle immediately as the GTS-320/R is turned on. The azimuth information won’t be missed even the GTS-320/R is power-off unexpectedly.

High-performance MCU SMT32

The SMT32 MCU based on ARM Cortexᵗᵐ-M processor enables the ZTS-320/R has extra high processing speed and low-power consumption.

Bluetooth

The bluetooth wireless technology makes GTS-320/R accessible to any data collector for real-time communication. The third party field software such as Carlson SurvCE is fully compatible with the GTS-320/R.

Data storage

Diversified data transfer options such as SD card, USB pen drive, mini-B interface.

Backlight

The display and keyboard with backlight for working in the dark.

Diagonal eyepiece

Support diagonal eyepiece for observation at steep line of sight.

Calibration Software

The proprietary calibration software is accessible for real-time diagnosis to ensure trouble-free operation.

Data transfer software

The proprietary data transfer software supports different type of output data format, which can be used in auto-CAD or other brands post processing software.
