FJD Trion V10L Laser RTK GNSS Rover and Base Set

FJD Trion V10L Laser RTK Rover and Base Set

The FJD Trion V10L Rover and Base Set provides a complete local RTK surveying solution built around two professional laser GNSS receivers. One V10L is configured as the fixed base station and transmits correction data, while the second receiver operates as the rover. This allows crews to achieve centimetre-level positioning without depending entirely on a regional NTRIP or CORS service.

The system is designed for land surveyors, construction teams, civil engineers, utility crews, GIS professionals and drone mapping operators. It is particularly useful on remote sites, infrastructure corridors, agricultural land, quarries, coastal projects and construction areas where mobile coverage or access to a permanent correction network cannot be guaranteed.

Independent Local RTK Corrections

During a local base-and-rover survey, the base receiver remains at a known or calculated position and continuously observes the available satellites. It sends real-time correction information to the rover through the integrated UHF radio. The rover combines these corrections with its own GNSS observations to calculate accurate coordinates in the field.

This workflow gives the crew direct control over the correction source and can provide more reliable project coverage than a mobile-data connection in remote or poorly connected areas. Either receiver can be assigned to the base or rover role according to the project setup, making the two-receiver system flexible across different jobs.

Non-Contact Laser Measurement

The V10L rover can measure a target without placing the survey pole tip directly on it. The operator aims the visible green laser at a wall corner, structural feature, riverbank, excavation edge, bridge component or other inaccessible point and records its coordinate from a safer or more convenient position.

Specified laser measurement accuracy is ≤2 cm within 5 metres, ≤3 cm within 10 metres and ≤4 cm within 15 metres. Automatic Gain Control supports laser ranging at distances of up to 80 metres by adapting to changes in target surface, light and distance. Actual results depend on RTK quality, target reflectivity, visibility, aiming stability and surrounding conditions.

Visible Green Laser for Clear Targeting

The visible green laser gives the operator a clear indication of the selected measuring or stakeout point. It is designed to remain practical in bright daylight as well as darker working environments, making target selection easier than with a laser that cannot be seen clearly on the surface.

A 2 MP night-vision camera supports work in low-light locations such as beneath bridges, around underpasses, inside partially covered structures and during early-morning or evening surveys. The live camera image allows the operator to confirm the selected target before accepting the measurement.

EasyFix Automatic Alignment

EasyFix combines the receiver camera, automatic alignment and zoom assistance to help the user locate and hold the intended target. This is useful when the point is small, located at a distance or surrounded by several similar features.

For tasks such as recording wall corners, bolts, utility markers, structural edges and road details, EasyFix can reduce repeated manual adjustments. The operator can view the feature through the controller, confirm the selected point and complete the observation without physically approaching the target.

AR and Laser Stakeout

The dual-camera system provides real-scene AR stakeout guidance. Direction and distance information are displayed over a live image of the working area, allowing the user to see where the design coordinate is located in relation to the surrounding site.

As the rover approaches the point, forward and downward views help guide the operator towards the target. Laser guidance can then indicate a position on a nearby surface without requiring the pole to be placed directly over every coordinate. This is practical for setting out near walls, barriers, excavation edges, traffic routes and restricted areas.

Second-Generation 60° IMU Tilt Compensation

The integrated IMU supports survey pole tilt angles from 0° to 60°. The pole does not need to remain perfectly vertical during every measurement, allowing crews to collect points beside walls, fences, vehicles, machinery, trenches and other obstacles.

The second-generation IMU is calibration-free and designed for fast initialization during normal field movement. Specified RTK accuracy with tilt compensation is 8 mm plus 0.6 mm for each degree of tilt under suitable conditions. This helps the operator work efficiently while avoiding the repeated stopping and careful pole levelling associated with conventional measurement methods.

1408-Channel Multi-Constellation GNSS

Each V10L receiver uses a 1408-channel GNSS board that tracks signals from GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS and SBAS. Access to multiple constellations and frequencies increases the number of satellites available for positioning and can improve solution availability near buildings, vegetation and other partial obstructions.

Under suitable RTK conditions, specified accuracy is 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically. Initialization is specified at under five seconds with reliability above 99.9%. Real field performance depends on the accuracy of the base position, baseline length, correction quality, satellite geometry, multipath and atmospheric conditions.

UHF Radio and Network RTK Connectivity

Integrated UHF radios allow correction data to be transmitted directly between the base and rover without an internet connection. This is the main advantage of the two-receiver set for projects outside established network RTK coverage.

The receivers also include integrated 4G modems for connection to compatible NTRIP or CORS services through a SIM card. This means either receiver can also be used as a network RTK rover where mobile coverage and correction access are available. Wi-Fi, Bluetooth, NFC, USB Type-C and external antenna connections provide additional options for controllers, data transfer and field configuration.

V10La and V10Li Options

The V10L platform is available in V10La and V10Li versions. The V10La supports non-contact laser measurement, laser stakeout, AR guidance and IMU tilt surveying. The V10Li adds image-based visual measurement, allowing several points to be selected from captured imagery.

The V10Li visual survey function has a typical specified accuracy of approximately 3 cm over a range of 2 to 15 metres. This version is useful for jobs involving several inaccessible targets or complex scenes, while the V10La is suited to standard point-by-point laser workflows. The supplied version depends on the chosen package configuration.

Receiver Display and Field Controls

A colour OLED display on each receiver provides direct access to important operating information. Status indicators, physical buttons and audio feedback allow crews to check GNSS reception, radio communication, battery condition and working mode without relying entirely on the field controller.

This is particularly useful during base station setup. The operator can verify that the base is tracking satellites and transmitting corrections correctly before moving away with the rover.

Rugged Equipment for Outdoor Projects

Each V10L receiver has an IP68-rated housing for protection against dust and water ingress. The enclosure is also designed to survive a two-metre pole drop, providing the durability required for daily use on construction, engineering and surveying projects.

At approximately 980 g per receiver, the V10L remains manageable on a survey pole while integrating the GNSS board, laser, cameras, UHF radio, 4G modem and battery. Its specified operating temperature range of approximately -35°C to 65°C supports work across a wide range of outdoor environments.

Battery Capacity for Base and Rover Work

The integrated 7000 mAh battery provides specified operating times of up to 15 hours in rover mode, 10 hours in base mode and more than 25 hours during static observations. Actual operating time varies with UHF radio power, laser use, camera activity, mobile connectivity, temperature and receiver settings.

Support for 30 W Power Delivery charging helps reduce downtime between working days. An external 9–28 V DC power input can be used to support longer base station occupations and extended projects.

Support from Global GPS Systems

Setting up a dependable local RTK system involves more than selecting two receivers. Base coordinates, antenna heights, radio frequencies, transmission power, coordinate systems, site calibration and controller software all influence the quality of the final results. Global GPS Systems can help users configure the V10L Rover and Base Set for their projects and select the appropriate receiver version, field controller and accessories.

The FJD Trion V10L Rover and Base Set is a flexible choice for teams that need an independent correction source together with laser measurement, visual stakeout and tilt surveying. It combines conventional centimetre-level GNSS work with safer non-contact measurement for points that cannot be reached efficiently with a survey pole.
