South Galaxy G7Q RTK GNSS Receiver with 60 Degree IMU

South Galaxy G7Q RTK GNSS Receiver

The South Galaxy G7Q is a miniaturized RTK GNSS receiver made for professional fieldwork in surveying, construction layout, civil engineering, GIS mapping and infrastructure measurement. It combines a 1598-channel GNSS engine, multi-constellation satellite tracking, 60° IMU tilt compensation, built-in UHF radio, WiFi, Bluetooth, NFC and 4G connectivity in a compact receiver weighing 907 g with the battery included.

For daily field crews, the G7Q is designed to keep RTK work practical. It is light enough to use comfortably on a pole during long survey days, but still includes the communication, positioning and durability features needed for centimetre-level point collection, stake-out and mapping. It is suitable for topographic surveys, construction control, road and utility work, cadastral measurement, GIS asset collection and drone ground control point measurement.

Compact receiver for everyday RTK surveying

The Galaxy G7Q is built around a compact 135 mm × 135 mm × 83 mm housing with a magnesium-aluminium alloy shell. This makes it a good fit for surveyors and construction teams who want a capable GNSS rover without carrying unnecessary weight. The receiver is easy to handle on busy sites, open field projects and mobile mapping jobs where equipment has to move quickly between points.

Single-button operation and four LED indicators make it simple to check the receiver status in the field. Operators can quickly see key information such as satellite tracking, data link, Bluetooth and power status without spending time inside menus during basic daily operation.

1598-channel GNSS performance for reliable positioning

The South Galaxy G7Q uses a 1598-channel GNSS board and tracks GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS signals. In real fieldwork, strong satellite availability helps maintain a usable RTK solution when working near buildings, machinery, roads, tree lines or other areas where the sky view is not always ideal.

For RTK surveying, the receiver is specified at 8 mm + 1 ppm horizontal accuracy and 15 mm + 1 ppm vertical accuracy. This makes it suitable for common centimetre-level tasks such as construction layout, stake-out, topographic surveys, boundary work, volume surveys, site control and engineering measurements when used with the correct correction source and field setup.

60° IMU tilt compensation for faster point measurement

The built-in IMU tilt compensation helps users measure and stake out points without keeping the pole perfectly vertical for every observation. This is especially useful when measuring close to walls, fences, trenches, slopes, parked machinery, stockpiles or other obstacles where levelling the pole is difficult or slow.

The IMU corrects the measured position to the pole tip and supports tilt angles up to 60°. For surveyors, construction workers and GIS field teams, this can make point collection faster and more natural. The calibration-free IMU design also helps keep the workflow simple, especially for teams that need reliable results without complicated setup steps.

Integrated UHF radio for base and rover workflows

The G7Q includes a built-in 2 W UHF radio for transmitting and receiving correction data. 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 receiver has a typical working range of 8 km, depending on terrain, antenna setup, radio conditions and local interference.

This makes the Galaxy G7Q useful for both rover-only and base-rover RTK workflows. A local base-rover setup is helpful on construction sites, remote projects and areas where mobile internet coverage or RTK network access is not reliable. When an RTK network is available, the receiver can also be used in NTRIP-based network RTK workflows through compatible field software and correction services.

4G WiFi Bluetooth and NFC connectivity

The South Galaxy G7Q supports several communication options to fit different field setups. Bluetooth can be used to connect the receiver with a controller or tablet, while WiFi gives access to receiver management and web interface functions. NFC supports quick close-range pairing with compatible controllers, helping crews connect equipment with less setup time.

The receiver also supports cellular network datalink functionality for network correction workflows. For teams that move between job sites, this communication flexibility makes the G7Q suitable for simple rover operation, local base-rover work and network RTK setups.

Long battery life for full working days

The built-in 7.2 V 6800 mAh rechargeable Li-ion battery is specified for up to 15 hours of use in rover Bluetooth mode. This gives surveyors, engineers and GIS users enough runtime for long field sessions without constantly planning around charging breaks.

The universal Type-C interface supports charging and can also be used for data transfer and access to internal functions. Power bank support is useful for longer projects, remote sites or teams that need to keep the receiver running through extended working days.

Designed for outdoor site conditions

The Galaxy G7Q is IP67-rated for water and dust protection, making it suitable for outdoor GNSS work in wet, dusty and demanding field environments. It is designed for the type of conditions often found on construction sites, road projects, open land surveys and infrastructure jobs, including rain, mud, dust, transport vibration and regular field handling.

The receiver also includes 4 GB internal storage as standard, expandable storage support, USB data transfer, FTP/HTTP data download, electronic bubble support, voice guidance and web interface management. These features help field users manage data, check receiver status and configure working modes more easily during daily use.

Who is the South Galaxy G7Q made for?

The South Galaxy G7Q is a strong choice for professionals who need a compact RTK GNSS receiver with tilt measurement and flexible communication. It fits surveyors collecting topographic data, construction workers setting out points, civil engineers checking site positions, GIS teams mapping assets and drone pilots measuring ground control points.

It is especially useful for users who want a practical GNSS receiver that can work with both UHF radio and network RTK workflows. The combination of 60° IMU tilt, 1598-channel tracking, integrated radio, 4G capability and long battery life makes it a versatile tool for daily positioning tasks.
