FJD Trion V10a RTK GNSS Receiver with AR Stakeout and 60° IMU

Compact RTK GNSS Receiver with Visual Stakeout

The FJD Trion V10a combines professional RTK GNSS positioning with cameras, IMU tilt compensation and several correction-data options in a compact receiver. It is designed for surveyors, construction teams, engineers, GIS professionals and other field users who need accurate coordinates without carrying a large or heavy GNSS receiver.

Its main advantage is the combination of conventional satellite positioning with visual field guidance. Instead of navigating to a stakeout point using only directional arrows, the operator can view guidance over the live camera image. This makes it easier to understand where the point is located in relation to the actual ground, nearby structures and construction features.

AR Stakeout for Faster Point Location

The V10a uses a forward-facing camera and a downward-facing camera, each with a 5 MP resolution. During supported stakeout workflows, the system displays visual guidance over the real-world view. This can reduce the time spent walking back and forth while searching for a design point.

For construction layout, the visual workflow helps operators relate digital coordinates to foundations, kerbs, utilities, columns and other physical site elements. CAD information can also be displayed in the site view, allowing personnel to inspect how a proposed layout relates to existing conditions before or during construction.

Visual stakeout is particularly practical for teams that do not use surveying equipment every day. The camera view provides additional context, while experienced surveyors can use it to improve efficiency on sites with many closely spaced points.

Measure with the Pole Tilted up to 60 Degrees

The integrated IMU compensates for survey-pole tilt up to 60°. The pole therefore does not need to be held perfectly vertical for every measurement. This makes it easier to record points beside walls, underneath vegetation, near parked machinery, along trenches or in other locations where access directly above the point is restricted.

Tilt measurement also helps maintain a smoother working pace. Operators can position the pole tip on the required point and record the measurement without repeatedly checking and adjusting a physical bubble. The tilt sensor is designed to remain usable around magnetic interference, reducing the need for time-consuming field calibration procedures associated with conventional magnetic sensors.

Multi-Constellation GNSS Tracking

With 1,408 tracking channels, the FJD Trion V10a receives signals from major GNSS constellations including GPS, GLONASS, Galileo and BeiDou. It also supports signals from QZSS, SBAS and other regional or correction services, depending on firmware and local availability.

Tracking several constellations and frequencies gives the receiver access to more satellites across the sky. In practical use, this can support more stable positioning around buildings, machinery, trees and other partial obstructions than a receiver that tracks fewer signals. As with every GNSS instrument, the best accuracy is achieved with a suitable correction source and a sufficiently open view of the sky.

Professional RTK Positioning

The receiver provides specified RTK accuracy of 8 mm + 1 ppm RMS horizontally and 15 mm + 1 ppm RMS vertically under suitable operating conditions. This makes it suitable for tasks such as construction set-out, topographic detail surveys, cadastral measurements, road and bridge work, utility mapping and site verification.

The V10a can also collect static and post-processing data for workflows that require measurements to be processed after fieldwork. Its 32 GB internal memory provides space for survey data and raw observations.

Flexible RTK Correction Options

An integrated 4G modem allows the receiver to obtain corrections from an NTRIP or RTK network using a compatible SIM card and data service. This is a practical rover configuration in areas with reliable mobile coverage because no local base station is required.

For projects without dependable mobile internet, the built-in UHF radio can receive or transmit corrections between compatible GNSS receivers. This allows the V10a to be used in a rover and base workflow, subject to the selected configuration, local radio regulations and field conditions.

Wi-Fi, Bluetooth and NFC provide additional options for connecting a data controller, transferring information and pairing equipment. A USB Type-C connection and ports for an external radio and UHF antenna are also provided.

Designed for Everyday Field Conditions

The receiver weighs approximately 800 g and measures about 130 mm in diameter and 68 mm in height. Its smaller form reduces the weight carried at the top of the survey pole, which can make a noticeable difference during long days of continuous measurement and stakeout.

The IP68-rated enclosure is dustproof and protected against continuous immersion to a depth of 1 metre under the stated test conditions. It is also designed to survive a 2 m pole drop. These features make the receiver suitable for construction sites, wet weather, dusty environments and regular transport between projects.

The specified operating-temperature range is from -35°C to 65°C. A waterproof and breathable membrane helps manage moisture in demanding outdoor environments.

Battery Life for Full Working Days

The built-in 4,900 mAh battery provides up to 15 hours of rover operation, up to 10 hours in base mode and more than 25 hours during static measurement, depending on working mode, temperature, communications and camera use. Support for 30 W USB Power Delivery fast charging helps reduce turnaround time between jobs.

Applications

The FJD Trion V10a is suited to a broad range of accurate positioning and layout work:

• Construction point and line stakeout
• Topographic and cadastral surveying
• Road, bridge and infrastructure projects
• Utility and pipeline data collection
• Earthworks, volume checks and site verification
• GIS asset mapping and control-point measurement
• River, coastline and environmental surveys

Construction workers can use the visual guidance to locate design points more intuitively. Professional surveyors benefit from the RTK, static and PPK measurement options. Engineers and GIS teams can collect accurate coordinates for site documentation, asset inventories and progress checks.

Choosing the Correct FJD Trion V10a Configuration

The final system can be configured for network RTK, UHF rover and base operation, visual stakeout or larger CAD and GIS workflows. Available controller options range from compact field controllers to larger rugged tablets, allowing the system to be matched to the software, drawing size and working method used by the operator.

Global GPS Systems can help determine the appropriate receiver, controller, software and correction-service configuration for the intended country and application. This is especially important when selecting UHF frequencies, mobile-network compatibility and accessories for an existing GNSS workflow.
