The i73 is an inexpensive CHCNAV GPS system. The system IS easy to setup and the results are accurate.
This product is a good fit for companies to expand into these technologies or add to their existing grade control infrastructure at a reduced price.

The i83 GNSS smart antenna delivers centimeter precision in seconds and maintains reliable fixed RTK accuracy even in typically challenging environments. Its quick-start feature gets you up and running within 30 seconds of powering up the receiver, making point collection faster than ever as you move from place to place. The third-generation high-gain antenna increases GNSS satellite signals tracking efficiency by up to 30% and provides accurate, survey-grade positioning when using GPS, Glonass, BeiDou, Galileo, and QZSS constellations. The integrated iStar technology ensures optimal GNSS RTK surveying in all GNSS survey applications.

The i93 is a highly versatile receiver that combines cutting-edge GNSS, Auto-IMU, RTK, and dual-camera technologies. It utilizes the iStar GNSS RTK algorithm, multi-band GNSS channels, and a hybrid engine to achieve precise positioning and surveying under challenging environments.
