Product Description
Product Description
CHC 1408 channels GNSS RTK i73 with Best-in-class Signal Tracking
The i73+ GNSS is an extremely compact, powerful and versatile GNSS receiver with an integrated UHF Tx/ Rx modem which can be used either as a base station or as a rover. Powered by CHCNAV iStar technology that optimally tracks satellite signals from all constellations, the i73+ GNSS achieves survey-grade, fixed RTK centimeter positioning within 30 seconds after power-up. In addition, its automatic pole tilt compensation increases the efficiency of point measurements by up to 20% and stakeout surveys by up to 30%. Easy to carry in one hand, the i73+ GNSS is an effective, lightweight GNSS solution that adapts to various job sites configurations, making intensive field surveys more convenient and less tiring for the operator.
