The i90 Pro GNSS receiver combines the latest CHCNAV’s IMU-RTK technology and the compatibility with L-Band corrections services to extend RTK positioning, in any locations.

Unlike the standard MEMS-based GNSS receivers, the i90 Pro GNSS IMU-RTK combines state-of-the-art GNSS RTK engine, a high-end calibration-free IMU sensor and advanced GNSS tracking capabilities to dramatically increase RTK availability and reliability.

The i90 automatic pole-tilt compensation boosts survey and stakeout speed by up to 20%. Construction and land surveying projects are achieved with high productivity and reliability pushing the boundaries of conventional GNSS RTK survey.
