South Galaxy G7Q RTK Base and Rover Set with IMU

South Galaxy G7Q RTK Base and Rover Set with IMU

The South Galaxy G7Q RTK Base and Rover Set with IMU is a complete two-receiver GNSS surveying package for professionals who need reliable centimetre-level positioning in the field. It is designed for surveyors, construction teams, civil engineers, GIS users and drone mapping professionals who want the flexibility of a local base-rover setup, while still having support for network RTK correction workflows.

The set includes two South Galaxy G7Q RTK GNSS receivers, a South H9 data collector, SurvStar surveying software, survey pole, controller bracket, tripod, tribrach and adapter. One receiver can be used as the base station and the other as the rover, allowing crews to work with their own correction source on construction sites, road projects, land surveys, utility jobs and remote locations.

Complete base and rover package for independent RTK work

A base and rover set is useful when you want to work independently from public RTK networks or when mobile internet coverage is not reliable on site. The base receiver is placed on a known point, tripod or site control position and sends correction data to the rover. The rover is then used to collect points, stake out designs and measure features across the project area.

This workflow is practical for construction layout, topographic surveying, road and infrastructure projects, cadastral work, earthworks, GIS mapping and drone ground control point measurement. It gives field crews more control over their correction source and is especially useful on private sites or in remote areas where network RTK access is limited.

1598-channel GNSS performance

Each South Galaxy G7Q receiver uses a 1598-channel GNSS engine and tracks GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS signals. In real fieldwork, multi-constellation tracking helps improve satellite availability when working near buildings, trees, machinery, slopes or other obstructions that can reduce sky visibility.

For RTK work, the G7Q is specified at 8 mm + 1 ppm horizontal accuracy and 15 mm + 1 ppm vertical accuracy. This makes the set suitable for common centimetre-level tasks such as topographic surveys, stake-out, site control, road alignment work, utility mapping, volume surveys and ground control point measurement.

60° IMU tilt compensation for faster point measurement

The built-in IMU tilt compensation helps the rover measure points without requiring the pole to be perfectly vertical for every observation. This is useful when measuring close to walls, fences, trenches, curbs, stockpiles, slopes, trees, parked machinery or construction materials.

The IMU supports tilt angles from 0° to 60° and corrects the measured position to the pole tip. For surveyors and construction workers, this can make point collection and stake-out faster, especially in places where levelling the pole is difficult or unsafe. The calibration-free IMU also keeps the workflow simple for field teams that need reliable results without complicated setup steps.

Integrated UHF radio for local base-rover surveying

The G7Q includes an internal 2 W UHF radio for sending and receiving correction data between the base and rover. It supports the 410 MHz to 470 MHz frequency range and communication protocols including Farlink, Trimtalk450s, SOUTH, HUACE, Hi-target and Satel.

With Farlink protocol, the typical radio working range is up to 8 km, depending on terrain, antenna setup, interference and local site conditions. This makes the set suitable for local RTK jobs where a dedicated base station is preferred over internet-based correction services.

Internet and network correction support

The South Galaxy G7Q also supports network correction workflows. The receiver specification includes WiFi hotspot access for the web interface, WiFi datalink for transmitting and receiving correction data, USB Type-C with Ethernet support, FTP/HTTP data download and support for NTRIP protocol with VRS, FKP and MAC network models.

In practical terms, this means the G7Q can be used in more than one correction workflow. Crews can work with the included local UHF base-rover setup when they want independence from internet coverage, or use supported network RTK workflows when correction data is available through a suitable internet connection, controller setup or site network.

South H9 controller and SurvStar field software

The included South H9 controller gives field users a rugged Android data collector for managing survey jobs, point collection, stake-out and receiver connection. It is designed for outdoor use and gives crews a dedicated field device instead of relying on a standard phone or tablet.

SurvStar software is included for field surveying workflows. It helps users manage GNSS measurements, coordinate systems, point files, stake-out tasks and field data collection. For construction teams, surveyors and GIS workers, this creates a more complete working package than a receiver-only setup.

Built for full working days outdoors

The G7Q receiver has a built-in 7.2 V 6800 mAh rechargeable Li-ion battery and is specified for up to 15 hours of operation in rover Bluetooth mode. The receiver supports charging through a universal Type-C interface and can also be powered from a power bank for longer field sessions.

The receiver housing is IP67-rated for water and dust protection and is built with a magnesium-aluminium alloy shell. It is designed for outdoor surveying environments where equipment may be exposed to rain, dust, mud, transport vibration and regular field handling.

Who is this set made for?

The South Galaxy G7Q RTK Base and Rover Set with IMU is a strong choice for users who need a complete RTK system with two receivers. Surveyors can use it for topographic work, cadastral measurement and site control. Construction teams can use it for layout, earthworks and as-built checks. GIS users can collect accurate asset data, and drone pilots can measure ground control points for mapping projects.

It is especially suitable for companies that want to work independently with their own base station, while still keeping the option to use network RTK correction workflows when available.
