i73+ IMU RTK GNSS

Product catalog summary

Overview: The i73+ GNSS is a compact and versatile GNSS receiver with an integrated UHF modem, suitable for use as a base station or rover. It utilizes CHCNAV iStar technology for optimal satellite signal tracking, achieving survey-grade RTK centimeter positioning within 30 seconds of power-up. The device features automatic pole tilt compensation, enhancing measurement efficiency by up to 30%.

Signal Tracking: The i73+ supports full GNSS with 1408 channels, leveraging signals from GPS, Glonass, Galileo, and BeiDou, including the latest BeiDou III. This ensures robust data quality and maintains centimeter-level accuracy.

GNSS+IMU RTK Technology: The built-in IMU initializes in 3 seconds, providing 3 cm accuracy up to a 30-degree pole tilt. This technology improves point measurement efficiency by 20% and stakeout by 30%, facilitating safer and more efficient surveys.

Design and Portability: Weighing only 0.73 kg, the i73+ is over 40% lighter than traditional receivers, featuring a rugged magnesium alloy design. It is easy to carry and operate, enhancing productivity in field surveys.

UHF Base and Rover: The integrated UHF modem supports major radio protocols, making the i73+ ideal for portable base and rover setups. It functions effectively as an NTRIP rover when connected to a GNSS RTK network via CHCNAV LandStar software.

Specifications: The i73+ includes Wi-Fi, NFC, and Bluetooth connectivity, with a 1408-channel capacity. It supports various GNSS signals and data formats, with a UHF radio range of up to 8 km under optimal conditions. The device is IP67 rated for water and dust resistance and operates in temperatures from -40°C to +65°C.

Performance: The i73+ offers high precision in RTK and static modes, with horizontal and vertical accuracies of 8 mm + 1 ppm RMS and 15 mm + 1 ppm RMS, respectively. It features a fast initialization time and high reliability, with a built-in battery providing up to 24 hours of operation in RTK rover mode.
