Pocket Design Surveying Instrument Rover CHCNAV i73 GNSS GPS RTK Receiver

Short Description:

The i73 GNSS is an extremely compact, powerful and versatile GNSS receiver. 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.

Full GNSS with 1408 Channels Advanced Tracking

The integrated advanced 1408-channel GNSS technology takes advantage of GPS, Glonass, Galileo and BeiDou, in particular the latest BeiDou III signal, and provides robust data quality at all times. The i73+ extends GNSS surveying capabilities while maintaining centimeter-level survey-grade accuracy. GNSS surveying has never been more efficient.

The Power of GNSS +IMU RTK Technology

Even in a complex electromagnetic environment, the i73 initializes its IMU in 3 seconds, with no need for repeated re-initialization. It delivers 3 cm accuracy up to a 30-degree pole tilt, increasing the efficiency of point measurement by 20% and stakeout by 30%. The i73 GNSS eliminates the challenge of measuring hidden or dangerous points while making the work of survey crews safer and more efficient. GNSS surveys are made easier by removing the need for the operator to focus on the perfect leveling of its surveying pole.

The Ultimate Pocket GNSS IMU Receiver

The i73 benefits from the ultra-compact magnesium alloy design of the i73 series, making it one of the lightest receivers in its class, weighing only 0.73 kg, including battery. The i73 is more than 40% lighter than a traditional GNSS receiver, making it more convenient to carry, use and operate without fatigue. The i73 GNSS is packed with technology, fits in your hands, and offers maximum productivity for GNSS surveys.
