Overview

About the G970II Pro

Full Support for BeiDou-3 Full Signal System

Compared to the previous-generation G970II, the G970II PRO upgrades the OEM board from the P328 to the high-precision BeiDou/GNSS positioning OEM board P40. The P40 is backward compatible with the P328 board, measures 6*10 cm, and doubles the channel count.

Enhanced Anti-Jamming Performance

The G970II PRO features chip-level anti-jamming technology to detect and suppress in-band and out-of-band GNSS interference signals, ensuring performance and accuracy in complex electromagnetic environments and improving operational availability.

Inherited Advanced IMU Tilt Compensation Technology

The G970II PRO inherits the superior integrated positioning technology of the previous generation, featuring a built-in high-precision IMU module and utilizing an integrated IMU tilt compensation and GNSS algorithm to deliver a new experience in RTK tilt surveying. In addition, it offers ultra-simple initialization, range pole calibration support for improved accuracy, and precise, reliable tilt measurement results (2 cm accuracy at up to 60° tilt), among other cutting-edge capabilities.

Low Power Consumption and Long Battery Life

The G970II PRO incorporates two highly integrated chips—Lyra II and Aquila—greatly simplifying circuit design. Combined with advanced power management and comprehensive algorithm engine optimization, overall power consumption is reduced by 30%, delivering extended operating life. The device comes with two hot-swappable, removable smart lithium batteries equipped with dedicated buttons and LED power indicators, allowing easy battery level checks without powering on. The symmetrical dual-battery, dual-compartment design with dual latches provides double security, while a recessed TNC antenna connector protects against drop impacts, setting a new standard in industrial design.

Additional G970II PRO Features

Data Controller Quick Pairing: Fast proximity pairing technology without requiring NFC hardware; Voice Shutdown Safety Lock: Real-time status alerts and shutdown confirmation via an intuitive voice assistant; Smart Base Station: Instant voice alerts on the rover upon any slight movement of the base station, with real-time base battery level and satellite tracking monitoring on the rover, keeping you fully informed even at long distances; Full UHF Radio Protocol Compatibility: Protecting the value of your equipment investments; Integrated Combination Antenna: 4-in-1 antenna reduces internal crosstalk, boosting the overall signal-to-noise ratio by more than 30%...
