Alpha 40 Laser AR GNSS RTK Receiver

The Alpha 40 Laser AR GNSS RTK Receiver is an optic-electric surveying receiver that combines GNSS RTK positioning, laser measurement, optical calibration, inertial navigation and dual-camera AR guidance in one compact unit.

Its laser measurement capability allows surveyors to collect points that are difficult or unsafe to occupy directly. The integrated inertial navigation system supports tilt compensation up to 60°, while the AR camera system provides visual assistance for surveying and stakeout workflows.

The Alpha 40 is also designed to support drone and unmanned-system positioning workflows, making it suitable for professional survey teams working across construction, infrastructure and mapping projects.

RTKSurvey.com supplies the Alpha 40 for professional surveying and non-contact measurement applications.
