The STEC AXIS SP streamlines surveys and stakeouts with high precision, automatic tracking, and one-person operation.
What makes it unique
Single-Person Operation
Its compact and portable design facilitates transport, installation, and operation by a single person on demanding or hard-to-reach terrain.
xTrak at 180°/s
The Torque Drive 2.0 motorization enables fast and stable rotations, speeding up searches, face changes, and tracking on site.
Automatic Recognition
The Auto Prism Recognize system automatically recognizes and measures the prism up to 1000 m, reducing manual aiming and operation times.
Torque Drive 2.0
Helps perform fast and stable turns during station changes, target searches, or repetitive measurement cycles on terrain.
Automatic Recognition
Allows automatic prism recognition and measurement up to 1000 m, useful when working with distant references or on extensive projects.
Prism Search and Tracking
The prism search covers 360° horizontal and 20° vertical up to 300 m; once locked, it can track a moving prism at 20°/s.
TERRA MASTER
Integrates data collection, staking, CAD, COGO, roads, multi-angle resection, and surface scanning in a visual work environment.

The station combines automatic prism recognition up to 1,000 m, search up to 300 m, xTrak tracking, and long-range Bluetooth of 600 m. These functions allow controlling and orienting the equipment remotely. The actual range depends on the line of sight, the environment, the prism, and the configuration used.
The station has selectable angular accuracy of 1″ or 2″ and distance accuracy of 1 + 1 ppm. The range with reflector is 3,500 m and can reach 5,000 m in Enhanced Mode. Automatic prism recognition works between 1.5 and 1,000 m; the 5,000 m mode must be validated according to configuration.
Yes. The AXIS SP declares a reflectorless range of up to 1,000 m. For distances less than 500 m, the indicated accuracy is 3 + 2 ppm; over 500 m, 5 + 2 ppm. The reported measurement time ranges from 0.4 to 3 s. Performance may vary depending on surface, lighting, and atmospheric conditions.
The automatic search works between 1.5 and 300 m, covers 360° horizontally and the technical brochure indicates 20° vertically. Once located, xTrak can track a moving prism at 20°/s.
Data collection, traverses, CAD staking, COGO, roads, multi-angle resection and surface scanning. It also integrates capture, staking and CAD in a single map, plus a multi-turn program for monitoring.
It includes Bluetooth 5.1 BLE of 10 m, long-range Bluetooth up to 600 m, WLAN of 2.4 and 5 GHz, mobile connectivity via SIM, RS232 and USB Type-C. These interfaces support remote control, data transfer and coordination between devices; regional SIM compatibility must be confirmed.
