The SatLab Eyr GNSS Receiver is an advanced high-precision GNSS RTK receiver designed to support modern surveying and geospatial data collection. This receiver introduces innovative dual-camera visual positioning technology, allowing surveyors to perform image-based measurement and AR visual stakeout for more intuitive and efficient field operations.
Equipped with a powerful GNSS chipset and multi-constellation satellite tracking capability, the Eyr delivers stable centimeter-level positioning accuracy even in challenging environments. The receiver supports up to 1408–1760 GNSS channels, ensuring strong signal tracking and improved resistance to interference.
The integrated HD dual cameras allow contact-free measurement and visual stakeout directly in the field. The rear 5 MP camera enables real-time coordinate capture at distances between 2–15 meters with an accuracy of approximately 2–4 cm, while the bottom camera supports AR-based live-view stakeout with around 2 cm accuracy, making stakeout faster and easier.
The receiver is also equipped with an upgraded IMU tilt compensation system, enabling accurate measurements even when the survey pole is tilted. With its compact and lightweight design, built-in radio communication, and long battery life, the Eyr GNSS receiver provides an efficient and reliable solution for professional surveying tasks.
