Spherefix SP30Pro RTK GNSS Receiver with AR and Photogrammetry

The Spherefix SP30Pro is a professional multi-constellation GNSS receiver designed for high-precision surveying, mapping, stakeout and photogrammetry workflows. It combines RTK positioning, an inertial measurement unit, AR-assisted stakeout and a built-in high-definition camera in one field-ready receiver.

The SP30Pro is intended for land surveyors, construction teams, civil engineers, mapping professionals, utility contractors, GIS specialists, road crews and other users who need accurate positioning and efficient field data collection.

Typical applications include topographic surveys, cadastral surveys, construction layout, road and infrastructure projects, earthworks, utility mapping, site documentation, point collection, boundary work and photogrammetric measurement.

Yes. The SP30Pro can operate as an RTK rover and receive correction data through a cellular network, radio link or another supported correction-data connection. The available workflow depends on the base station, correction service, controller software and regional network configuration.

The receiver supports professional GNSS and radio communication workflows that may allow it to be configured as a base station. Confirm the required base-and-rover configuration, radio settings and supplied accessories with Spherefix before deployment.

The SP30Pro is focused on camera-based photogrammetry and detailed site measurement. The standard SP30 uses a camera-assisted laser measurement module. Both models support high-precision GNSS positioning, AR stakeout, tilt compensation and multiple communication methods.

The SP30Pro supports signals from GPS, BeiDou, GLONASS, Galileo, QZSS, SBAS and NavIC. Its 1408-channel architecture is designed to track multiple frequencies and constellations for improved availability in demanding survey environments.

When properly configured with suitable RTK corrections and good satellite conditions, the SP30Pro is designed for centimeter-level positioning. Published specifications list RTK accuracy of approximately ±(8 mm + 1 ppm) horizontally and ±(15 mm + 1 ppm) vertically. Actual results depend on correction quality, satellite visibility, baseline length, multipath and field procedures.

Yes. Its integrated inertial measurement unit supports pole-tilt measurements at angles of up to 60 degrees, with a stated tilt-compensation accuracy of less than 2 cm under suitable operating conditions.

No. Tilt compensation allows surveyors to collect points without keeping the pole perfectly vertical. This can speed up measurements beside walls, under obstacles, near building corners and in other locations where conventional pole leveling is difficult.

AR real-scene stakeout displays directional guidance over a live camera view of the jobsite. Instead of relying only on arrows or numerical offsets, the operator can see a more intuitive visual path toward the design point.

The photogrammetry function combines images from the receiver’s wide-angle camera with GNSS and inertial positioning data. It is designed to help users measure or document visible site features from captured imagery, including points that may be difficult or unsafe to reach directly.

The SP30Pro includes a 1/2.6-inch high-definition wide-angle camera. The camera supports photogrammetric surveying and AR-assisted stakeout when used with compatible field software and a suitable Android controller.

The receiver supports 4G cellular connectivity, Bluetooth, Wi-Fi and an integrated LoRa data radio. These options allow it to connect to controllers, correction networks, base stations and other compatible field equipment.

Yes. It includes a configurable 1 W, 2 W or 5 W LoRa radio operating in the 410–470 MHz range. Permitted frequencies and power levels vary by country, so users must follow local radio regulations.

Yes. Its 4G connectivity can be used for network RTK workflows, including compatible NTRIP correction services. A SIM card, mobile data service, correction-service account and correctly configured field software may be required.

Yes. In areas without mobile coverage, correction data may be transmitted from a compatible local base station through the built-in radio. The achievable radio range depends on terrain, antennas, interference, mounting height, power settings and local regulations.

The receiver can be paired with a compatible Android field controller. Spherefix offers the C500 controller, which features Android 12, a 5.5-inch sunlight-readable display, a physical keyboard, Bluetooth, Wi-Fi, 4G connectivity and an IP68-rated housing.

Software compatibility depends on the selected controller, communication protocol, data format and project workflow. Before purchasing, confirm support for the required coordinate systems, stakeout tools, NTRIP services, file formats, photogrammetry functions and export options.

The receiver supports commonly used professional GNSS data and correction workflows, including NMEA-0183 and RTCM 3.x. Confirm the exact messages and protocol compatibility required by your controller, base station or correction network.

The built-in 7.4 V, 10000 mAh battery is rated for more than 24 hours of operation in rover mode under specified conditions. Runtime can vary with radio power, cellular use, temperature, satellite tracking and other active functions.

The receiver supports USB Power Delivery at 12 V/2 A, USB DCP charging at 5 V/3 A and external 9–24 V DC power. Use approved cables, chargers and power sources that meet the manufacturer’s specifications.

The SP30Pro is designed to meet IP68 protection requirements, helping protect it against dust and water during demanding outdoor survey work. All ports and covers must be properly closed to maintain environmental protection.

The receiver has a magnesium-alloy housing and is specified to withstand a 1.5 m pole drop at room temperature. Proper handling, transport protection and routine inspection are still recommended.

The published operating-temperature range is approximately -20°C to 60°C. Battery performance, radio range and measurement conditions may be affected near the limits of the operating range.

A typical setup includes the SP30Pro receiver, survey pole or tripod, compatible field controller, survey software, charging equipment and either an RTK correction-service connection or a compatible base station. Project coordinate systems, antenna height, communication settings and correction parameters must be configured before collecting production data.
