Spherefix SP30 Laser RTK GNSS Receiver with AR Stakeout

Spherefix SP30 Multifunctional RTK GNSS Receiver

The Spherefix SP30 is a multifunctional RTK GNSS receiver developed for surveying, construction layout, topographic measurement, GIS data capture and other positioning work where speed and flexibility matter. It brings conventional GNSS surveying, tilt-compensated measurement, camera-guided stakeout and laser-assisted point capture together in one field receiver.

This combination helps field teams handle more situations without constantly changing equipment or measurement methods. The SP30 can be used on a survey pole for standard RTK work, tilted when a point cannot be occupied vertically, or with its camera and laser functions when the required location is difficult to reach directly.

Measure Points That Are Difficult to Occupy

The integrated laser surveying function is intended for points where placing the pole tip is inconvenient, obstructed or potentially unsafe. The aiming camera helps the operator identify the required point, while the laser and positioning system support remote point capture.

In practical fieldwork, this can be useful near building façades, behind barriers, at road edges, around excavations, beneath structures or on other features that are awkward to occupy with a standard GNSS pole. It allows the operator to remain in a more convenient position while still collecting the required point.

AR Real-Scene Stakeout

The SP30 includes a wide-angle camera for augmented-reality stakeout. Instead of relying only on arrows, distances and a plan view, the operator can see stakeout guidance over the live camera image.

This makes it easier to understand the direction of the target point when working on busy construction sites or in open areas where visual references are limited. It can also help less experienced operators approach a point more confidently and reduce unnecessary movement during layout work.

Fast Tilt-Compensated Surveying

Integrated inertial measurement technology allows the SP30 to compensate for a tilted pole over an operating range of up to 60°. The manufacturer specifies positioning accuracy of less than 2 cm within this tilt range under suitable operating conditions.

Tilt compensation means the pole does not need to be carefully levelled for every observation. Surveyors can measure against walls, near corners, beside parked equipment, beneath vegetation and in other restricted locations where holding the pole vertically would slow down the job. This supports faster point collection while reducing physical strain during repetitive surveys.

Multi-Constellation GNSS Tracking

The 1,408-channel receiver tracks multiple frequencies from GPS, GLONASS, BeiDou, Galileo, QZSS, SBAS and NavIC. Access to a broad range of satellite signals helps the receiver maintain useful satellite geometry in changing field conditions.

This is especially valuable near buildings, trees and site machinery, where part of the sky may be obstructed. No GNSS receiver can eliminate the effects of severe blockage or reflected signals, but multi-frequency, multi-constellation tracking gives the operator more signals to work with and supports reliable RTK performance in suitable environments.

Centimetre-Level RTK Positioning

For RTK work, the stated accuracy is ±(8 mm + 1 ppm) horizontally and ±(15 mm + 1 ppm) vertically. In practical terms, this makes the SP30 suitable for construction setting out, boundary and topographic surveys, utility mapping, control work and detailed GIS data collection when it is used with suitable corrections and good surveying practice.

As with all high-precision GNSS equipment, achievable accuracy depends on satellite visibility, correction data, baseline length, atmospheric conditions and the amount of signal reflection or obstruction around the measurement point.

Flexible Correction and Communication Options

The SP30 provides 4G mobile connectivity for network RTK and NTRIP correction services. It also includes an adjustable 5 W UHF radio for local base-and-rover operation. Bluetooth and Wi-Fi support connections with field controllers, software and other compatible equipment.

These communication options allow the receiver to fit different working methods. A surveyor can connect to a regional correction network where mobile coverage is available or use a local GNSS base station and radio link on sites where an independent setup is preferred.

Designed for Professional Field Users

The Spherefix SP30 is suitable for construction workers setting out positions, surveyors collecting topographic or boundary data, engineers checking site features, GIS teams recording assets and infrastructure, and drone operators establishing accurate ground control or verification points.

Its combination of standard RTK measurement, tilt surveying, visual stakeout and laser-assisted capture is particularly useful for teams that work across varied sites and want one receiver capable of handling both routine observations and less accessible points.
