The X12IMU-RTK GNSS Series is designed to dramatically increase GNSS real-time kinematic (RTK) availability and reliability.The X12 is powered by the company's latest inertial measurement unit (IMU) and RTK technology to provide robust and accurate GNSS positioning in any circumstances.Unlike standard micro-electro-mechanical (MEMS)-based GNSS receivers, the X12GNSS IMU-RTK combines a high-end calibration and interference-free IMU sensor with a state-of-the-art GNSS RTK engine and advanced GNSS tracking capabilities.The X12is designed to increase productivity and reliability of survey projects. No complicated calibration process, rotation, leveling or accessories are necessary with the X12 GNSS Series. Just a few meters' walk will initialize the X12 internal IMU sensor and enable RTK survey in difficult field environments. The X12 GNSS automatic pole-tilt compensation boosts survey and stakeout speed by up to 20%."Our new X12 IMU-RTK GNSS Series is pushing the boundaries of conventional GNSS survey by extending RTK positioning availability and reliability," said George Zhao, CEO of CHC Navigation. "CHCNAV is the GNSS technology enabler, making high-end GNSS solutions available for every surveyor."
