Product Feature And Application
Field Staking-Get It Right the First Time
·A combination of satellite navigation, inertial navigation, and visual positioning algorithms significantly reduces the impact of electromagnetic interference, ensuringprecise staking.
·By integrating RTK with imagery, staking points are marked directly on the image, allowing for quick point identification and getting the job done right the first time.
·Dual AR imagery on both the handheld device and the main unit provides intelligent guidance throughout the entire staking process,
doubling efficiency.
Inertial Navigation Surveying · Tilt-Free
· Sitolli's fourth-generation inertial navigation tilt measurement technology is immune to electromagnetic interference and requires no bubble leveling-simply raise the pole to start measuring and perform stakeout while walking.
