CHCNav i73+

Description

A compact GNSS receiver that supports high-precision positioning, the CHCNav i73+ marks the next step in RTK positioning and base station technology. With built-in IMU-RTK technology to support satellite tracking and GPS accuracy at tilts of up to 30 degrees, the CHCNav i73+ is a versatile piece of surveying equipment that sets a new standard in GIS data collection.

CHCNav i73+ Key Features

• Compact & Lightweight – weighing only 0.73 kg, the CHCNav i73+ is hyper-portable, allowing for easy transportation and operation in the field.

• Survey-Grade Accuracy – using iStar technology, the CHCNav i73+ achieves survey-grade, fixed RTK centimetre positioning within just 30 seconds after power-up, making it suitable for surveying applications.

• Integrated UHF Modem – the CHCNav i73+’s built-in UHF Tx/Rx modem allows the uni to be used as both a base station and a rover.

• Advanced GNSS Tracking – the CHCNav i73+ utilises 1408 channels to optimally track signals from all 5 GPS, GLONASS, Galileo, QZSS, and BeiDou constellations to provide superior RTK positioning accuracy.

• IMU-RTK Technology – using industry-leading IMU-RTK technology, the CHCNav i73+ provides 3 cm accuracy with pole tilt compensation up to 30 degrees, improving efficiency and safety in measurements.

• Rugged Design – the durable magnesium alloy construction and IP67 dust and waterproof rating of the CHCNav i73+ allows it to perform optimally in even the harshest environments and weather conditions.
