Spherefix SP10 RTK GNSS Rover Base Set with 60 Degree IMU

Complete RTK Rover and Base Set for Independent Fieldwork

The Spherefix SP10 RTK GNSS Rover Base Set provides the main equipment required to establish a local GNSS base and carry out centimetre-level measurements with a mobile rover. It is intended for land surveyors, construction professionals, civil engineers, GIS teams and other users who need accurate positioning in areas where a permanent RTK correction network is unavailable, unsuitable or outside project requirements.

The set combines two Spherefix SP10 receivers with a Spherefix C100 data collector, surveying software, survey pole and controller bracket. A tripod, tribrach and adapter are included for setting the base receiver securely over a control point. Accessories and software can be adjusted where a project requires a different controller or field workflow.

Use One SP10 as a Base and One as a Rover

During rover-and-base work, one SP10 is installed on the tripod and configured as the base receiver. The second SP10 is mounted on the survey pole and carried around the site as the rover. The base observes GNSS signals from its fixed location and generates correction data that helps the rover determine accurate coordinates.

This setup is useful on construction sites, remote survey areas and temporary projects where the crew wants to control the source of its RTK corrections. It can also provide a practical alternative where mobile RTK network coverage is inconsistent or where a project must work from its own site control.

The accuracy of the complete workflow depends on the quality of the base coordinates. Placing the base on an incorrectly entered or poorly determined position can shift every rover measurement. For reliable project coordinates, the base should be established on a verified control point or positioned using a suitable static, averaged or localisation procedure.

Internet-Based Corrections or External Communication Required

The SP10 includes 4G mobile-network connectivity, Bluetooth and Wi-Fi, but it does not have an internal UHF radio. This means the two receivers cannot exchange long-range radio corrections directly without additional equipment.

A common configuration is to send base corrections over the internet and receive them at the rover using an NTRIP-compatible workflow. This requires suitable mobile coverage, SIM or data access and correctly configured correction settings. Where internet coverage is unavailable, a compatible external radio or other supported communication solution may be required.

Buyers should confirm the intended correction link before ordering. Global GPS Systems can help match the receiver set with the required connectivity, controller, software and accessories.

Measure with the Rover Pole Tilted up to 60 Degrees

The SP10 rover includes an inertial measurement unit that compensates for a pole angle of up to 60°. Operators can therefore measure many points without taking extra time to centre the pole bubble perfectly before every observation.

Tilt compensation is particularly useful when collecting points beside walls, fences, parked vehicles, machinery and building corners. It also helps when measuring kerbs, banks, trenches and uneven terrain where keeping the pole vertical is awkward or unsafe.

The IMU is designed to operate without a separate startup calibration routine. Under suitable RTK conditions, the specified positioning error caused by tilt remains below approximately 2 cm within the supported range. Actual results depend on the correction link, satellite visibility, multipath, pole-height settings and field procedure.

Multi-Constellation GNSS Tracking

Each SP10 uses 1,408 channels to track GPS, GLONASS, Galileo, BeiDou and QZSS signals. Receiving multiple constellations gives both the base and rover access to a larger group of satellites, improving the availability of observations across normal construction and surveying environments.

This can be valuable on sites with partial sky obstruction from buildings, trees or equipment. Multi-constellation tracking cannot remove all signal blockage or reflection, but it gives the positioning engine more observations to use when calculating the RTK solution.

Centimetre-Level RTK Positioning

Under suitable field conditions, the SP10 has a specified RTK accuracy of ±8 mm + 1 ppm horizontally and ±15 mm + 1 ppm vertically. This performance supports construction setting-out, topographic surveys, utility mapping, control work, as-built documentation and other tasks where conventional standalone GPS accuracy is insufficient.

For construction teams, the rover can be used to locate foundation points, grid lines, drainage features, roads, kerbs and design coordinates. Surveyors can collect detail points, establish temporary control and stake out boundaries or engineering designs. GIS professionals can record utilities and infrastructure with more reliable coordinates than ordinary handheld navigation equipment.

Surveying Software for Collection and Stakeout

The included field software supports the main workflow around the SP10 receivers. Users can create and manage projects, connect to the receiver, configure rover and base modes, select coordinate systems and manage measured points.

Available measurement workflows include topographic points, control points, quick measurements and automatic point collection. The software also supports point stakeout, tilt measurement, localisation, point calibration, coordinate databases and data export.

In practical terms, crews can import or enter design coordinates, navigate to the required position and place a marker on the ground. Collected survey points can then be stored with names and codes before being exported for CAD, GIS or office processing.

Tripod and Tribrach for Stable Base Setup

The supplied tripod, tribrach and adapter allow the base receiver to be positioned securely over a survey mark. A stable base installation is important because movement of the receiver during the survey can affect all coordinates produced by the rover.

The tribrach allows careful centring and levelling over the control point, while the tripod gives the receiver a fixed platform for the duration of the work. The base should be placed where it has a clear view of the sky and is protected from vehicles, machinery and accidental disturbance.

Long Battery Endurance for Field Operations

Each SP10 contains a 9,600 mAh internal lithium battery. Typical operating endurance is stated at approximately 16 hours, depending on receiver mode, mobile-network activity, temperature, battery condition and configuration.

This capacity is intended to support a normal working day. For extended base operation, remote projects or multi-shift work, an appropriate charging or external-power arrangement should still be planned. Charging is handled through a USB Type-C connection.

Compact Housing for Outdoor Surveying

The SP10 uses a magnesium-alloy body and is designed for portable outdoor work. Its IP65 protection rating helps protect the receiver from dust and water jets encountered during normal surveying and construction activities.

Status indicators allow the operator to check power, satellite positioning, Bluetooth and correction activity directly on the receiver. The web interface can be used to review receiver status, configure operating modes, manage data streams, access stored files and update firmware.

Applications for the Spherefix SP10 Rover Base Set

The set is suitable for construction layout, earthworks, road and drainage projects, topographic mapping, site control, utility surveys, as-built measurements and land-surveying tasks. Drone operators can also use it to establish ground control and independent check points for photogrammetry, provided the survey procedure meets the accuracy requirements of the project.

GIS and asset-management teams can use the rover to collect accurate positions for pipes, cables, inspection points, street furniture and environmental features. Because the set includes its own base receiver, it can be deployed on temporary sites without relying entirely on a third-party correction network.

Configuration and Support from Global GPS Systems

A rover-and-base system must be configured as a complete workflow. The receivers, controller, field software, coordinate system, correction link and base coordinates all need to work together correctly. Global GPS Systems can help select the appropriate configuration and explain whether internet corrections or an external radio solution is best suited to the project.

The Spherefix SP10 Rover Base Set is a practical choice for teams that want two compact GNSS receivers, calibration-free tilt measurement and the flexibility to establish their own RTK base. It is especially suitable for buyers who understand that the SP10 uses network communication rather than a built-in UHF radio for transmitting corrections.
