South Galaxy G4 Rover Set RTK GNSS Receiver with IMU

South Galaxy G4 Rover Set

The South Galaxy G4 Rover Set is a complete RTK GNSS rover solution for professional fieldwork. It is designed for surveyors, construction professionals, civil engineers, GIS users and mapping teams who need reliable centimetre-level positioning without building a system from separate parts. With the South Galaxy G4 receiver at the centre of the set, users get a modern GNSS rover with strong satellite tracking, IMU tilt compensation, 4G connectivity and internal UHF communication.

This rover set is suitable for daily work on construction sites, infrastructure projects, land surveys, road layouts, topographic surveys, utility mapping, stakeout tasks and as-built measurements. It gives field crews the flexibility to work with RTK correction networks through 4G or connect to a local base station using the internal UHF radio.

Designed for efficient rover surveying

The South Galaxy G4 Rover Set is made for users who spend most of their time collecting points, checking positions and staking out designs in the field. The receiver uses a 1698-channel S805 GNSS engine, allowing it to track a wide range of satellite signals from major constellations. In practical fieldwork, this helps the rover maintain a stable RTK solution and improves performance when satellite visibility is less than perfect.

For surveyors and engineers working near buildings, trees, embankments, machinery or site cabins, strong satellite tracking is important. The G4 is designed to use more available signals, helping crews keep moving instead of waiting for a fixed position longer than necessary.

60° IMU tilt compensation for difficult points

The integrated IMU tilt sensor helps make field measurements faster and more practical. Instead of carefully levelling the pole for every point, users can measure with the pole tilted up to 60°. This is useful when measuring building corners, fence lines, trench edges, kerbs, slopes, road shoulders, walls or other points where holding the pole perfectly vertical is difficult.

For construction workers and survey crews, this can save time across a full working day. It also helps reduce awkward measuring positions, especially in areas with traffic, obstacles, vegetation or limited access. The tilt workflow is especially useful during stakeout, where crews often need to move quickly between points while keeping the work accurate and efficient.

Flexible RTK correction options

The South Galaxy G4 Rover Set supports different ways of receiving RTK corrections. The built-in 4G modem is suitable for working with RTK correction networks through NTRIP. This is a practical setup for many surveyors, contractors and GIS teams who work in areas with mobile internet coverage.

For projects without stable mobile coverage, the internal UHF radio gives the rover another option. It supports the 410–470 MHz range and common radio protocols such as Farlink, Trimtalk and SOUTH. This makes the rover useful for local base-rover workflows where corrections are sent directly from a base station on site.

Built for real job sites

The Galaxy G4 receiver has a rugged AZ91D magnesium alloy body designed for strength and heat dissipation. The yellow housing is a practical advantage in the field because it makes the receiver easier to see on construction sites, roadside projects, open terrain and areas with vegetation. Better visibility helps protect the equipment and makes it easier for crews to spot the instrument during busy fieldwork.

The receiver is built for outdoor use and includes communication options such as Bluetooth, WiFi, NFC, Type-C and RS232. The Web UI can be accessed through WiFi or cable, allowing users to check receiver status, configure settings, manage radio parameters, review satellite information and handle receiver setup tasks when needed.

Suitable for surveying, construction and GIS workflows

The South Galaxy G4 Rover Set is a good fit for land surveyors who need a dependable rover for topographic work, boundary measurements, control surveys and stakeout. It is also useful for construction teams that need accurate position checks for earthworks, foundations, site layout, road projects and as-built documentation.

GIS users and asset mapping teams can use the rover set for collecting accurate field data on utilities, drainage, signs, roads, boundaries, vegetation, infrastructure and other mapped objects. Drone pilots and mapping professionals can also use it for ground control points and checkpoint measurements when accurate georeferencing is required.

A complete rover package for professional field teams

Buying the South Galaxy G4 as a rover set makes it easier to start working in the field because the receiver is supplied as part of a practical RTK workflow rather than as a standalone instrument only. This is useful for companies that want a ready-to-use rover setup for their surveyor, engineer, construction crew or GIS team.

Global GPS Systems can help match the South Galaxy G4 Rover Set with the right controller, software, RTK network setup, base station workflow and accessories. This helps buyers choose a complete GNSS solution that fits the way they actually work, whether that is construction layout, survey measurement, GIS data collection or general RTK field positioning.
