South Galaxy G7Q Product Review

Supercharged by SoC technology

The Galaxy G7Q, powered by the SOUTH SoC platform, is designed with most of its components—such as the GNSS module, Wi-Fi, and Bluetooth—consolidated on a single circuit board. This efficient integration results in reduced power consumption and enhanced satellite signal reception quality. Equipped with the latest SoC GNSS board, next-generation high-sensitivity satellite antenna, updated ROS platform, and advanced GNSS RTK engine, the G7Q can track GPS, GLONASS, BDS, GALILEO, and QZSS to achieve centimeter-level accuracy within seconds. The G7Q now also supports BeiDou-3 B2b L-band BDS-PPP corrections, providing real-time centimeter-level positioning services. Additionally, the new “RTK Keep” feature allows the G7Q to maintain centimeter-level accuracy for a few minutes, even when RTK corrections are temporarily unavailable.

Ultimate goals of full signals tracking

The Galaxy G7Q features an integrated high- and low-frequency antenna design, utilizing low-profile technology to minimize physical disparities between frequency bands and improve phase center consistency. With a frequency-selective radiation mechanism, this design also enhances the antenna’s anti-interference capabilities. Paired with a high-performance GNSS board, the G7Q fully supports all active satellite constellations, with a special emphasis on the BeiDou III global satellite signals.

Moving ahead into the future

The Galaxy G7Q is powered by an advanced SoC chip that offers high integration and low power consumption. This setup effectively suppresses interference signals, allowing for higher-quality observation data from satellite constellations. The G7Q delivers a significant leap in RTK performance, enhancing the user experience.

Worry-free surveying

The new SoC platform generation enhances RTK stability while reducing power consumption. With a built-in 6800mAh high-performance battery, the G7Q supports up to 15 hours of continuous use. Its Type-C charging interface enables PD fast charging, allowing the battery to fully recharge in just 3 hours—ideal for all-day operation.

Measure whatever you want

The Galaxy G7Q incorporates a next-generation Inertial Measurement Unit (IMU) for improved stability and accuracy in tilt measurements. The coordinates are automatically adjusted based on the pole’s inclination direction and angle, allowing surveyors to measure points without needing to level the receiver precisely. This feature enhances productivity by up to 30 percent.

Smart reminder of base station attitude

The South Galaxy G7Q includes a built-in high-precision tilt attitude module that tracks the receiver’s orientation. If the base station shifts or tips over, the module accurately detects this change and provides an immediate alert.

 Longer Battery Life

With SOC technology, the G7Q achieves higher performance while consuming less power. Its built-in 6800mAh Li-ion battery enables up to 15 hours of continuous use in Rover Bluetooth mode. The G7Q also features a Type-C charging interface with PD fast-charging support, fully recharging the battery in just 3 hours for all-day operation. Additionally, it now supports an external portable phone battery, allowing work to continue even when the internal battery is depleted.

IMU for Tilt Survey

The Galaxy G7Q is equipped with the latest Inertial Measurement Unit (IMU) featuring anti-magnetic properties, allowing tilt surveys to start anywhere. Simply shake to initialize the IMU sensor—no calibration required. With an IMU data output rate of up to 200Hz, it significantly enhances fieldwork efficiency.
