South G9

The G9 rover integrates advanced technologies, including Intelligent Base signal locking, RTK integration, and Farlink protocol, enhancing the convenience of field surveying. Its UHF module with Farlink communication enables an impressive 10km working range. The Smart ROS system optimizes hardware components, ensuring efficient and reliable tilt measurement with a wide angle range. The built-in high-performance IMU compensator improves accuracy and productivity, allowing users to continue surveying even after a fixed solution is lost. The dual-battery system design provides a 15-hour working time in Rover+Bluetooth mode, with hot replaceable batteries for uninterrupted field work.

    Features

    High integration creates convenient field work

    Carrying a new RTK integration technology, Bluetooth, WIFI, GSM antennas are highly integrated into GNSS antenna, that brings you an unprecedented experience of field surveying, making the field work more convenient and easier.

    Advantageous SoC (System-on-Chip) platform

    The GNSS board of G9 is upgraded to the most advanced SoC which is a high integration chip that has 1598 channels for multi-constellation and multi-frequency tracking, efficiently suppresses the interference signals, and obtains higher quality observation data from GNSS constellations.

    Intelligent Base signal locking technology

    Using one-to-one signal tracking and locking technology, and the independent frequency under Farlink protocol, the G9 rover can continuously lock and capture the target base station signal to reduce cross-frequency interference even though other base stations are working nearby with the same channel.

    The ultimate internal UHF performance

    The G9 breaks through the constraints on wavelengths based on a SOUTH high-performance UHF module with Farlink communication technology, which increases signal sensitivity and transmission efficiency, and really achieves the goal of 10km ultra-long-distance working range.

    Powerful system management

    G9 is integrated with the ROS system, which comes with intelligent deployment of multi-mode hardware components, strong computing power and an intelligent scheduling mechanism, and coupling with an ultra-fine memory management mechanism, making the fluency and running speed of the receiver comprehensively improved.

    Efficient and reliable tilt measurement

    Built-in high-performance IMU automatic compensator co rects the coordinates to the pole tip, assisting users to quickly and accurately measure or stake out points at will without strict leveling the receiver. The tilt angle range can achieve up to 60°

    Furthermore, the compensation is still available even tho gh the fixed solution is lost for a short time. Users can continue the survey after the fixed solution recovers without initializing the IMU module again, which helps surveyors boost productivity by 30 percent.

    Super long working hours

    G9 also adopts a dual-battery system design so that it can achieve longer battery life while maintaining strong performance. The hot replaceable function allows you to change the battery one by one when power is low. You can continue with work without switching off the receiver.

    The G9 receiver is able to continuously work for about 15 hours in Rover+Bluetooth mode with 2 batteries. Power volume is visible synchronously on the control panel.
