Spherefix SP30 Pro Rover Set with AR and Photogrammetry

A complete RTK rover solution for professional fieldwork

The Spherefix SP30 Pro Rover Set brings together the receiver and field-control equipment required for accurate GNSS surveying, construction layout and geospatial data collection. It is designed for land surveyors, civil engineers, construction crews, utility teams and GIS professionals who need dependable centimetre-level positioning in an efficient mobile setup.

At the centre of the set is the Spherefix SP30 Pro, a multifunctional RTK GNSS receiver that combines conventional satellite positioning with AR real-scene stakeout, photogrammetry and IMU tilt compensation. These functions help crews perform more of their measurement and setting-out work directly in the field, including tasks where a target is difficult to occupy with the survey pole.

1408-channel multi-constellation GNSS tracking

The SP30 Pro uses 1408 GNSS channels and tracks signals from GPS, GLONASS, BeiDou, Galileo, QZSS, SBAS and NavIC. Access to multiple constellations and frequencies gives the receiver more satellites to work with and supports reliable RTK positioning across different regions.

In practical fieldwork, this broad signal support is useful when surveying near buildings, vegetation or other objects that partially restrict the view of the sky. Local conditions still affect GNSS performance, but using more available satellite systems can improve positioning availability compared with relying on a limited selection of signals.

Visual guidance with AR real-scene stakeout

Stakeout work normally requires the operator to follow arrows, distances and offsets displayed on the field controller. The SP30 Pro adds an ultra-wide-angle camera that can show stakeout guidance over a live view of the site. This makes it easier to understand which direction to walk and where the design point is located in the real environment.

AR stakeout is particularly helpful when placing foundation points, utility markers, road features, grid lines and other construction positions. The visual workflow can make point navigation more intuitive for experienced surveyors as well as construction personnel who do not work with GNSS equipment every day.

Photogrammetry for difficult-to-reach features

The SP30 Pro includes a separate wide-angle imaging function for photogrammetric measurement. Working with the receiver’s inertial navigation system and compatible field software, it can determine points from captured images instead of requiring the pole tip to be placed directly on every feature.

This offers a practical way to collect building corners, façades, trench details, stockpiles, road edges and objects behind fences or other obstructions. It can also reduce the need to enter unsafe or inconvenient positions. Measurement suitability and achievable accuracy depend on the working distance, image geometry, calibration, software and field conditions.

Measure efficiently with a tilted pole

The integrated IMU supports tilt compensation through an angle of up to 60°. Spherefix states positioning accuracy below 2 cm within the supported tilt range. Once the IMU is initialised, the operator can measure without carefully levelling the pole for each point.

This is useful beside walls, under vegetation, near parked machinery and on uneven surfaces where holding the pole vertically can be awkward. It can also speed up routine topographic surveys, as-built measurements and construction checks by reducing the time spent centring the bubble.

Network RTK and radio correction options

The receiver includes 4G mobile connectivity, Wi-Fi, Bluetooth and an integrated data radio operating within the 410–470 MHz range. This allows the rover to receive corrections from an NTRIP or network RTK service where suitable mobile coverage is available. It can also work with a compatible local GNSS base station over radio.

The appropriate correction method depends on the project location, available infrastructure and required working range. Radio frequencies, transmission power and permitted operation vary by region, so the receiver should be configured according to local regulations and the base equipment used on site.

Field controller for data collection and stakeout

The rover set includes a rugged Android field controller for operating survey software, managing jobs, viewing maps and recording measured points. A physical keypad and outdoor-readable touchscreen support practical operation while wearing gloves or working in bright conditions.

The controller connects to the GNSS receiver wirelessly and provides access to coordinate systems, coding, stakeout files and field-measurement functions. Software compatibility and the included application or licence should always be checked against the intended workflow before ordering.

Built for full working days

The SP30 Pro receiver uses a high-capacity internal battery that provides more than 24 hours of continuous operation in rover mode under the manufacturer’s stated conditions. This reduces the need to interrupt normal survey work to replace or recharge the receiver battery.

A magnesium-alloy body and IP68 environmental protection help the receiver withstand dust, rain and everyday site use. Spherefix also specifies resistance to a 1.5 metre pole drop at room temperature. As with all precision equipment, careful handling and regular checks are recommended to protect measurement performance over time.

Applications for the Spherefix SP30 Pro Rover Set

The set is suitable for a wide range of positioning and measurement tasks, from straightforward construction marking to professional geospatial surveys. Its combined GNSS, camera and IMU functions are especially useful for crews that need to switch between conventional pole measurements, visual stakeout and indirect point collection during the same project.

• Topographic, cadastral and detail surveying
• Construction point, line and surface stakeout
• Road, earthworks and utility projects
• GIS asset collection and infrastructure mapping
• As-built measurements and site verification

Choosing your rover set with Global GPS Systems

Global GPS Systems can help match the Spherefix SP30 Pro Rover Set to your preferred RTK network, base station, coordinate system and field-software workflow. This is important when combining the rover with existing equipment or when regional radio settings and mobile-network compatibility must be considered.

For buyers comparing professional RTK GNSS equipment, the SP30 Pro Rover Set offers a versatile combination of multi-constellation tracking, visual stakeout, photogrammetry, IMU tilt compensation and integrated field communications in one mobile surveying package.
