FJD Trion V10i Visual RTK GNSS Rover and Base Set

FJD Trion V10i Rover and Base RTK GNSS Set

The FJD Trion V10i Rover and Base Set provides a complete local RTK surveying system built around two versatile visual GNSS receivers. One receiver is configured as the base station at a known or calculated position, while the second receiver works as the rover and receives correction data through the integrated UHF radio. This gives surveyors and construction teams the flexibility to establish their own RTK correction source on sites where network RTK coverage is unavailable, unreliable or unsuitable for the required workflow.

Because both units are V10i receivers, the system is not limited to fixed base-and-rover roles. Crews can assign either receiver as the base or rover depending on the project setup. The V10i can also be configured for base station or static operation using its physical buttons, providing a practical setup option when a field controller is not immediately connected.

A Complete Local RTK Surveying Workflow

A base-and-rover system is especially useful on remote construction sites, agricultural land, infrastructure corridors, quarries, coastal areas and other locations where a dependable mobile data connection cannot be guaranteed. The base receiver observes the available satellites from a fixed position and transmits correction information to the rover. The rover then uses those corrections to calculate centimetre-level coordinates in real time.

This setup gives the survey crew greater control over the correction source and avoids relying entirely on a third-party CORS or NTRIP network. When network RTK is available, the integrated 4G modem also allows a V10i receiver to connect through a SIM card, so the equipment can be adapted to both local-radio and internet-based correction workflows.

Visual Measure for Inaccessible Survey Points

The V10i rover integrates a 2 MP forward camera and a 5 MP downward camera with GNSS and IMU positioning. Its Visual Measure function allows the operator to capture images of a point that cannot be reached safely or conveniently with the survey pole. The receiver processes multiple images and positioning data to calculate the coordinate of the selected feature.

This is practical for measuring points across trenches, behind barriers, beside busy roads, at building edges or near unstable ground. The manufacturer specifies typical visual measurement accuracy of approximately 3 cm over a working range of 2 to 15 metres. Results depend on site geometry, image quality, satellite conditions and correct field procedure, but the feature can reduce the need to place the operator directly beside difficult or hazardous points.

AR Stakeout with Live Camera Guidance

AR Stakeout displays the target point within the live camera view on the field controller. Instead of following only numerical distances and directional arrows, the operator can see where the required point is located in relation to the real site.

This makes stakeout navigation easier to understand during construction layout, utility work and general setting-out tasks. It helps the user approach the target efficiently before carrying out the final precise positioning step. The visual interface can also make RTK equipment more approachable for construction workers and engineers who do not perform surveying work every day.

Calibration-Free 60° IMU Tilt Compensation

The integrated IMU compensates for survey pole tilt at angles up to 60°. The pole therefore does not need to remain perfectly vertical while measuring a point. This is useful beside walls, under vehicles, near fences, around machinery, on sloping surfaces and wherever the operator cannot position the pole directly above the required feature.

The tilt system is calibration-free and designed to resist magnetic disturbance. This is important on active construction and infrastructure sites, where steel structures, tools, vehicles and equipment may interfere with conventional magnetic sensors. Tilt compensation allows faster point collection while reducing the need to stop and carefully level the pole for every observation.

Multi-Constellation GNSS Performance

Each V10i receiver uses a 1408-channel GNSS engine capable of tracking GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS signals. Access to multiple satellite constellations and frequencies increases the number of usable satellites and can improve positioning availability around buildings, vegetation and other partial obstructions.

Under suitable RTK conditions, the specified positioning accuracy is 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically. Positioning update rates of up to 20 Hz support responsive point collection and stakeout work. Actual field accuracy remains dependent on the base position, baseline length, satellite geometry, correction quality, multipath and surrounding conditions.

Integrated UHF Radio and Flexible Connectivity

The integrated UHF radios allow the base and rover to exchange RTK corrections directly without requiring an internet connection. This is the core advantage of the two-receiver package for teams working outside established network RTK coverage.

The receivers also support an integrated 4G modem, dual-band Wi-Fi, Bluetooth 5.2, NFC, USB Type-C and external antenna connections. These options make it possible to connect field controllers, use NTRIP correction services, transfer data and adapt the system to different working environments.

Clear Receiver Status in the Field

A 1.41-inch true-colour OLED screen displays operating information directly on each receiver. Operators can check GNSS, communication, battery and working-mode status without relying entirely on the controller display. Physical buttons provide direct control over basic functions, while LED indicators and audio feedback help the crew confirm the current receiver state.

This is particularly useful during base station setup, where the receiver may be positioned on a tripod some distance from the rover operator. The display gives the crew a clear way to verify that the base is operating and transmitting correctly before starting survey work.

Rugged Construction for Outdoor Surveying

Each receiver has an IP68-rated enclosure designed to resist dust and water ingress. The housing is also designed to survive a two-metre pole drop. At approximately 970 g per receiver, the V10i remains manageable on a survey pole while providing the protection needed for regular use on construction, engineering and infrastructure projects.

The specified operating temperature range is suitable for varied field environments, and a waterproof breathable membrane helps manage internal moisture when equipment is exposed to changing temperatures and weather conditions.

Battery Capacity for Base and Rover Operation

Each V10i has an integrated 7000 mAh battery. The specified operating time is up to 15 hours in rover mode, 10 hours in base mode and more than 25 hours in static mode. Actual battery life varies according to radio output, camera use, temperature, mobile connectivity and operating conditions.

Support for 30 W power delivery charging helps reduce downtime between working sessions. An external 9 to 28 V DC input is available for longer base station occupations, allowing the base receiver to be connected to a suitable external power source during extended projects.

Applications for the V10i Rover and Base Set

The set is designed for land surveyors, construction professionals, civil engineers, utility crews, GIS teams and drone mapping operators who require an independent centimetre-level positioning solution. Surveyors can use it for cadastral, topographic, detail and control work, while construction teams can use it for layout, position checks, as-built measurements and site preparation.

Utility and GIS professionals can collect accurate coordinates for cables, pipes, chambers, valves and other assets. Drone operators can survey ground control points and checkpoints for photogrammetry. The visual measurement tools are particularly useful when project features are close to traffic, across water, behind safety barriers or otherwise difficult to reach with a pole.

Typical Field Uses

• Local RTK base and rover surveying
• Construction setting out and site measurement
• Cadastral and boundary surveying
• Topographic and terrain surveys
• Road, bridge and infrastructure projects
• Utility and GIS asset mapping
• Ground control points for drone mapping
• Remote sites without dependable mobile RTK coverage

Support from Global GPS Systems

A reliable rover-and-base workflow depends on more than the receivers themselves. Radio frequencies, base coordinates, coordinate systems, antenna heights, site calibration and field software settings all affect the final result. Global GPS Systems can help users configure the FJD Trion V10i Rover and Base Set for their intended projects and understand the available controller, software, radio and accessory options.

For teams that need the independence of a local RTK base station together with visual measurement, AR stakeout and tilt surveying, the FJD Trion V10i Rover and Base Set provides a flexible solution for everyday surveying and construction work.
