The CHCNAV i73+ is a compact, high‑performance GNSS RTK receiver designed for maximum field productivity. Powered by a 1408‑channel GNSS engine, it tracks all major satellite constellations to deliver robust, high‑quality positioning in demanding environments. Its built‑in UHF modem allows the i73+ to operate seamlessly as either a base or rover, while LandStar software enables efficient NTRIP workflows.

Weighing only 0.73 kg, the magnesium‑alloy i73+ is exceptionally portable and reduces operator fatigue during long field sessions. Its automatic pole tilt compensation—up to 60°—boosts point measurement efficiency by 20% and stakeout productivity by 30%, eliminating the need for precise pole leveling.

With an IP67‑rated rugged design, extended 6800 mAh battery, and up to 24 hours of RTK rover operation, the i73+ is built for reliability in harsh field conditions. Whether used for construction layout, topographic surveys, or cadastral mapping, the i73+ delivers professional‑grade performance in a compact, flexible package.
