Spherefix SP10 RTK GNSS Rover Set with 60 Degree IMU

Complete Network RTK Rover Set for Accurate Field Measurement

The Spherefix SP10 RTK GNSS Rover Set provides surveyors, construction professionals, engineers and GIS teams with a practical package for centimetre-level positioning. Instead of supplying only the GNSS receiver, the set combines the SP10 with a Spherefix C100 data collector, surveying software, survey pole and controller bracket. This creates a coordinated field solution for collecting points, setting out coordinates and managing survey data.

The lightweight receiver is designed for crews that move regularly around construction sites, roads, boundaries and large survey areas. At approximately 510 g, the SP10 adds less weight to the survey pole than many conventional GNSS receivers, helping reduce fatigue during long periods of stakeout or detail measurement.

Measure Difficult Points with a Tilted Survey Pole

The SP10 includes an integrated inertial measurement unit that compensates for pole angles of up to 60°. The operator can therefore measure many points without holding the pole perfectly vertical or repeatedly centring the pole bubble.

In practical fieldwork, this is useful when measuring beside walls, beneath overhangs, at building corners, along fences or close to parked machinery. It can also make measurements on banks, uneven ground and busy construction sites more convenient. The inertial system does not require a separate startup calibration routine, allowing the operator to begin tilt measurements with fewer preparation steps.

The specified tilt accuracy is less than 2 cm within the supported 60° range under suitable operating conditions. Final accuracy remains dependent on satellite visibility, correction quality, pole-height settings, multipath and the surrounding environment.

Multi-Constellation Tracking for Reliable Positioning

The receiver uses 1,408 channels to track signals from GPS, GLONASS, Galileo, BeiDou and QZSS. Using several constellations gives the receiver access to a larger number of satellites and observations, which can help maintain a usable solution across typical surveying and construction environments.

Multi-constellation tracking is particularly valuable on sites where parts of the sky are obstructed by buildings, trees or equipment. It cannot completely remove the effects of signal blockage and reflection, but it gives the positioning engine more information to work with than a receiver that supports fewer systems.

Centimetre-Level Network RTK Surveying

The Spherefix SP10 is designed primarily as a network RTK rover. Its integrated 4G modem connects to a compatible NTRIP or CORS correction service using a suitable SIM card and data connection. This allows crews to work within an established RTK network without setting up a local radio base station for every project.

The specified RTK accuracy is ±8 mm + 1 ppm horizontally and ±15 mm + 1 ppm vertically under suitable conditions. This level of performance supports common applications such as construction stakeout, topographic surveys, site control, boundary-related measurement, utility mapping and as-built recording.

The SP10 does not contain an internal UHF radio. Buyers planning to work outside mobile-network coverage or with a radio base station should confirm the required external communication equipment before selecting their configuration.

Field Controller and Surveying Software Included

The included Spherefix C100 data collector provides the interface between the operator, the GNSS receiver and the surveying software. It can be mounted to the supplied survey pole using the controller bracket, keeping measurements, maps and stakeout information visible while working.

The surveying software supports the essential workflow around the receiver, including connecting to the GNSS equipment, configuring rover corrections, measuring points and managing coordinate data. Available field functions include topographic point collection, control-point measurement, quick measurements, automatic point collection, point databases and stakeout workflows.

For construction teams, this means design coordinates can be taken into the field and located on the ground. Surveyors can collect coded points for later processing, while GIS and utility users can record accurate asset positions and associated information.

Suitable for Construction Surveying and GIS Work

On construction projects, the set can be used to position foundations, grid lines, drainage features, kerbs, roads and other design elements. It can also support excavation checks, stockpile or surface measurements and the recording of completed work. Tilt compensation is especially useful when the required point is close to a structure or cannot be approached with a vertical pole.

Land surveyors can use the SP10 for detail surveys, control densification, coordinate stakeout and static observations. GIS teams can collect accurate locations for utilities, street furniture, environmental assets and infrastructure inspections. Drone operators may also use the rover to survey ground control and independent check points for photogrammetry projects, provided the complete control workflow meets the project’s accuracy requirements.

Long Battery Endurance for Mobile Crews

The SP10 contains a 9,600 mAh lithium battery and is specified for more than 16 hours of typical rover operation while using its mobile-network connection. This is intended to support a normal field day without stopping to replace the receiver battery.

The USB Type-C charging interface supports several compatible charging profiles. Actual working time will vary with temperature, network use, receiver settings and battery condition, so crews working remotely should still plan suitable charging or backup power.

Compact Receiver Built for Outdoor Conditions

The receiver uses a magnesium-alloy main body with an ABS and polycarbonate upper cover. Its IP65 protection rating helps protect it against dust and water jets during normal outdoor fieldwork. It is also specified to withstand a 1.5 m pole drop at room temperature.

An operating-temperature range of −20°C to +60°C makes the receiver suitable for a wide range of climates. Status indicators show power, satellite positioning, Bluetooth and differential correction activity, allowing operators to check essential receiver conditions directly in the field.

Flexible Rover Set Configuration

The standard product listing combines the SP10 receiver with a C100 data collector, Spherefix surveying software, a survey pole and controller bracket. The controller, software and accessories may be adapted where a project requires a different tablet, field application or pole configuration.

Compatibility should be confirmed before changing any component. Coordinate systems, correction-network access, data formats and software licensing can all affect whether a rover set fits an existing survey workflow.

Buying the Spherefix SP10 from Global GPS Systems

Global GPS Systems can help buyers confirm the appropriate controller, surveying software, pole accessories and RTK correction service for their work. This is particularly important for users moving from standalone GPS equipment to centimetre-level network RTK, as the receiver, field software, coordinate-system settings and NTRIP account must work together correctly.

The Spherefix SP10 Rover Set is well suited to professionals looking for a lightweight and complete network RTK package with calibration-free tilt compensation, multi-constellation tracking and enough battery capacity for a full working day.
