South Galaxy G4 Rover Base Set RTK GNSS with IMU Tilt

South Galaxy G4 Rover Base Set

The South Galaxy G4 Rover Base Set is a complete RTK GNSS field package for professionals who need a rover and base station setup for accurate positioning on site. It is designed for land surveyors, construction companies, civil engineers, GIS teams, road contractors, utility mappers and drone mapping professionals who need reliable centimetre-level measurements in the field.

Unlike a rover-only setup, a rover and base set allows your team to create its own local RTK correction link. This is useful on projects where mobile network corrections are not available, not preferred, or where a dedicated site base gives better control over the workflow. The set can also support flexible working methods, because the G4 includes both 4G connectivity and internal UHF radio communication.

Complete RTK setup for independent fieldwork

The South Galaxy G4 Rover Base Set is made for teams that want to start working with a complete GNSS system instead of buying separate parts. The set includes the core equipment needed for a practical rover and base workflow, including the receiver setup, South H6 data collector, SurvStar surveying software, surveying pole, controller bracket, tripod, tribrach and adapter.

For construction crews and surveyors, this makes the set suitable for site layout, control points, topographic surveys, boundary work, road projects, earthworks, stakeout and as-built checks. The base receiver can be placed on a known or temporary point, while the rover is used to collect measurements or stake out design positions across the site.

1698-channel GNSS engine for reliable satellite tracking

The Galaxy G4 uses an S805 GNSS engine with 1698 channels. In real fieldwork, this helps the receiver track more signals and maintain a stable RTK solution in a wider range of conditions. The receiver supports major satellite constellations and signals, including GPS, GLONASS, Galileo and BeiDou, giving survey teams more satellite availability during daily work.

This is especially useful when working near buildings, trees, machinery, embankments or other obstacles that can reduce satellite visibility. For surveyors and engineers, strong GNSS tracking helps reduce waiting time and keeps the field crew moving through the job more efficiently.

60° IMU tilt compensation for faster measuring

The integrated IMU tilt compensation helps users measure points without keeping the pole perfectly vertical every time. The South Galaxy G4 supports tilt measurements up to 60°, which is helpful when measuring points near walls, fences, kerbs, trenches, slopes, building corners, road edges or other hard-to-reach locations.

For a rover and base workflow, this improves productivity across the full site. The rover operator can move faster between points, measure awkward positions more easily and reduce the time spent carefully levelling the pole for every shot. This is useful for both experienced surveyors and construction teams that need accurate results with a practical field workflow.

UHF and 4G for flexible RTK corrections

The South Galaxy G4 includes an internal UHF radio in the 410–470 MHz range. In a rover and base set, this allows the base receiver to send corrections directly to the rover on site. This is valuable for remote locations, infrastructure projects, construction sites and rural areas where mobile internet coverage may not be stable enough for network RTK.

The receiver also includes a 4G internet modem, so the rover can work with NTRIP correction services when network RTK is the preferred method. This gives field teams the choice between local base corrections and internet-based corrections, depending on the project, location and required workflow.

Built for demanding outdoor environments

The Galaxy G4 receiver has a rugged AZ91D magnesium alloy body designed for durability and heat dissipation. The yellow housing is practical on construction sites, roadsides and outdoor survey areas because it makes the instrument easier to see from a distance. This can help protect the equipment and improve visibility for crews working in busy or low-light conditions.

For daily field users, the receiver also includes practical communication and setup options such as Bluetooth, WiFi, NFC, Type-C and RS232. The internal Web UI can be accessed through WiFi or cable, allowing users to check receiver status, configure communication settings, manage radio parameters and review satellite information when needed.

For survey, construction, GIS and mapping professionals

The South Galaxy G4 Rover Base Set is a strong choice for users who need more independence than a rover-only system. Surveyors can use it for control surveys, topographic measurements, stakeout and boundary-related work. Construction teams can use it for site setup, layout, earthworks, road projects, utility positioning and as-built documentation.

GIS and asset mapping teams can use the rover for accurate field data collection, while drone pilots can measure ground control points and checkpoints for mapping projects. Because the set includes both rover and base capability, it is also suitable for companies that work across different locations and cannot always rely on external correction networks.

A practical GNSS package from Global GPS Systems

The South Galaxy G4 Rover Base Set is designed for field teams that want a complete, flexible and professional RTK GNSS setup. It combines strong satellite tracking, IMU tilt measurement, UHF base-rover communication and 4G network capability in one practical package.

Global GPS Systems can help match the South Galaxy G4 Rover Base Set with the right field workflow, controller setup, software configuration, RTK network use and accessories. This helps surveyors, construction crews and GIS users choose a GNSS solution that fits the way they actually work in the field.
