South Galaxy G7Q RTK Rover Set with H9 Controller

South Galaxy G7Q RTK Rover Set with H9 Controller

The South Galaxy G7Q RTK Rover Set with H9 Controller is a complete GNSS surveying package for professionals who need accurate centimetre-level positioning in the field. It includes the South Galaxy G7Q RTK GNSS receiver, South H9 Android data collector, SurvStar surveying software, a survey pole and a controller bracket.

This rover set is made for land surveyors, construction workers, civil engineers, GIS teams, utility contractors and drone mapping professionals who need a practical RTK setup for point collection, stake-out, mapping and ground control point measurement. It is suitable for daily fieldwork where accuracy, fast setup, tilt measurement and internet-based RTK correction workflows are important.

Complete RTK rover package for field measurement

A rover set is useful when you want a ready-to-use GNSS field setup instead of buying the receiver, controller, software and pole accessories separately. The South Galaxy G7Q Rover Set gives field crews the main components needed to start working with RTK corrections from a compatible base station or an online RTK correction network.

The included South H9 data collector and SurvStar software help the operator manage survey jobs, collect points, stake out positions and work with field data on site. For construction and surveying companies, this makes the system practical for setting out foundations, checking site positions, mapping utilities, measuring terrain and collecting as-built points.

1598-channel GNSS receiver for centimetre-level RTK work

The South Galaxy G7Q receiver uses a 1598-channel GNSS engine and tracks GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS signals. In real field conditions, this helps maintain strong satellite availability when working on construction sites, roads, open fields, infrastructure projects and mixed environments where sky visibility can change during the day.

For RTK positioning, the G7Q is specified at 8 mm + 1 ppm horizontal accuracy and 15 mm + 1 ppm vertical accuracy. This makes the rover set suitable for common professional measurement work such as topographic surveys, stake-out, boundary work, utility mapping, road surveys, site checks, earthworks and drone ground control point measurement.

60° IMU tilt compensation for faster point collection

The built-in IMU tilt compensation helps users measure points without keeping the pole perfectly vertical for every observation. This is useful in everyday fieldwork, where the required point is often close to a wall, fence, curb, trench, slope, tree, machine or construction material.

With tilt compensation up to 60°, the receiver corrects the measured position back to the pole tip. For surveyors and construction professionals, this can make point collection and stake-out faster, especially in awkward locations where careful pole levelling takes extra time. The calibration-free IMU also keeps the workflow simple for users who need reliable results without complicated setup steps.

Internet connectivity with 2 Nano SIM slots

The South Galaxy G7Q RTK Rover Set supports internet-based RTK workflows through the included South H9 controller. The H9 controller has 2 Nano SIM slots, a 4G cellular module, LTE band support, WiFi and Bluetooth 5.0. This allows field crews to connect to online correction services directly from the controller when using a suitable SIM card, mobile data plan and RTK network subscription.

For surveyors and construction teams, this is important in daily use. It means the rover set can work with NTRIP correction services in the field without needing a separate mobile hotspot or phone tethering setup. The controller provides the internet connection, while the GNSS receiver uses the correction data for centimetre-level RTK positioning.

Network RTK and NTRIP support

The South Galaxy G7Q supports network RTK workflows including NTRIP, VRS, FKP and MAC correction models. In practical terms, this allows the rover to use correction data from compatible RTK networks when an internet connection is available through the H9 controller.

This workflow is useful for surveyors, engineers, GIS users and drone pilots working across multiple sites. Instead of setting up a local base station every time, users can connect to a correction service through the H9 controller and start collecting accurate RTK points in the field, depending on local RTK network coverage and subscription access.

Integrated UHF radio for local base station corrections

The South Galaxy G7Q also includes a built-in 2 W UHF radio operating in the 410 MHz to 470 MHz range. It supports Farlink, Trimtalk450s, SOUTH, HUACE, Hi-target and Satel radio protocols. With Farlink protocol, the typical working range is up to 8 km, depending on terrain, antenna setup, interference and local field conditions.

This gives users two practical ways to work. On sites with good mobile internet access and an RTK correction service, the rover set can use network RTK through the H9 controller. On projects where mobile coverage is poor or a private correction source is preferred, the G7Q can receive corrections from a compatible local UHF base station.

South H9 controller for professional field operation

The South H9 is a rugged Android 12 data collector designed for surveying and mapping work. It has 4 GB RAM, 64 GB internal storage, an 8-core processor, a 6 inch touchscreen and a full QWERTY keypad. The physical keypad is useful when entering point names, codes and measurements in wet conditions or when wearing gloves.

The H9 also includes dual-band WiFi, Bluetooth 5.0, NFC, 4G cellular connectivity and 2 Nano SIM slots. Its 7700 mAh battery supports long working days, while the IP68 housing and 1.5 m drop resistance make it suitable for demanding outdoor sites where equipment has to handle dust, rain, transport and daily use.

Built for long working days outdoors

The G7Q receiver has a built-in 6800 mAh rechargeable battery and is specified for up to 15 hours of operation in rover Bluetooth mode. The Type-C interface supports charging, data transfer and external power support from a power bank, which is useful for longer field sessions.

The receiver has an IP67-rated housing and weighs approximately 907 g with the battery included. Its compact body makes it comfortable for pole-mounted rover work during long survey days, while the one-button operation and LED indicators help users quickly check receiver status in the field.

Who uses the South Galaxy G7Q Rover Set?

The South Galaxy G7Q Rover Set is made for professionals who need accurate GNSS measurements in a complete and manageable field package. Land surveyors can use it for topographic work, boundary surveys and control points. Construction teams can use it for layout, stake-out and as-built checks. GIS professionals can collect accurate asset positions for utilities, roads, drainage, signs, trees and infrastructure. Drone pilots can use the rover set to measure ground control points for photogrammetry projects.

Because the set includes the receiver, controller, software and pole accessories, it is also a practical choice for companies building a new RTK workflow or replacing older GNSS equipment with a modern IMU rover system. The built-in SIM support in the H9 controller makes it especially useful for users who want a straightforward internet connection for NTRIP corrections in the field.
