Stonex S999 GNSS Receiver

Stonex S999 GNSS Receiver

The S999 is Stonex's most capable all-in-one GNSS receiver, combining every feature a modern surveyor needs into a single, compact, and rugged unit. Tracking all satellite constellations across 1408 channels at 50Hz, it delivers rock-solid centimeter-level positioning in every environment. Its advanced IMU tilt compensation handles pole inclinations up to 60°, boosting field productivity by up to 40% by eliminating the need to perfectly level the pole on every shot. The S999's dual-camera system is a true standout, with a front camera for real-time visual stakeout guidance that automatically switches to a precision lower camera as you close in on the target, and a second camera dedicated to photogrammetric 3D modeling via Cube-3D software. A dual-frequency UHF radio and integrated 4G modem ensure seamless connectivity for both base-rover and network RTK workflows across any distance. Rated IP68 and built to operate from -40°C to +65°C, the S999 is the ultimate all-terrain, all-condition surveying solution.
