FJD Trion V1t IMU RTK GNSS Rover and Base Set

The FJD Trion V1t Rover & Base Set is a professional RTK GNSS surveying system consisting of a base receiver, a rover receiver and an FJD E600 field controller. The base transmits correction data to the rover, enabling accurate real-time positioning without depending on a separate local RTK network.

The system is designed for land surveyors, construction contractors, civil engineers, precision agriculture professionals, GIS teams, utility crews, machine-control specialists and other users who require reliable centimetre-level positioning in the field.

The set can be used for topographic surveys, point collection, boundary measurement, construction layout, point and line stakeout, road stakeout, terrain modelling, CAD-based stakeout, precision agriculture and general engineering measurements.

A rover and base set allows users to create their own local RTK correction source. This is useful in areas where no CORS or NTRIP network is available, mobile internet coverage is unreliable or recurring access to a third-party correction service is undesirable.

Yes. Although the receivers are supplied for rover and base operation, each V1t receiver can be configured according to the required field workflow. One unit can operate as the base while the other works as the rover, and the roles can be changed when necessary.

Yes. The system can support site layout, excavation checks, road construction, grade verification, utility positioning, foundation stakeout and as-built measurements. Its tilt-compensated rover is particularly useful when measuring beside structures or around obstacles.

The specified RTK accuracy is ±(8 mm + 1 ppm) horizontally and ±(15 mm + 1 ppm) vertically under suitable operating conditions. Actual accuracy depends on satellite visibility, radio reception, baseline length, correction quality, atmospheric conditions and the surrounding environment.

The specified RTK initialization time is less than five seconds when the baseline is shorter than 10 km and field conditions are suitable. Initialization may take longer where satellite visibility is restricted or correction signals are interrupted.

The receiver supports GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS and IRNSS signals. Its 1,408 tracking channels help maintain reliable positioning by using signals from multiple satellite constellations and frequencies.

Yes. The integrated inertial measurement unit allows measurements to be taken while the survey pole is tilted. This reduces the need to level the pole for every point and makes it easier to measure corners, walls, building edges and other obstructed locations.

The tilt survey specification is approximately 2.5 cm horizontal accuracy at a 30-degree pole angle. The system supports a maximum tilt angle of up to 60 degrees, although accuracy can vary according to the tilt angle, calibration and field conditions.

Galileo High Accuracy Service Precise Point Positioning uses correction information transmitted through Galileo signals. It can provide an additional positioning option where local RTK corrections are unavailable, although its accuracy and convergence time differ from a fixed RTK rover-and-base solution.

The base receiver calculates corrections from its known or measured position and transmits them to the rover through the integrated UHF radio. The rover applies these corrections to produce an accurate real-time position.

The system is available with a 410–470 MHz or 902–928 MHz internal radio configuration, depending on the selected version and region. Users must ensure that the chosen frequency range and transmission settings comply with local radio regulations.

The practical radio range depends on transmission power, antenna height, terrain, vegetation, buildings and local interference. A clear line of sight between the base and rover normally provides the best performance. An external radio solution may be required for especially large or obstructed sites.

The FJD Trion V1t supports commonly used protocols including LoRa, TRIMTALK, TRIMMARK III, T450S, TRANSEOT and Satel 3AS 4FSK. Matching the frequency, protocol, channel and radio settings is essential when connecting to compatible third-party equipment.

Yes. The rover can receive network RTK corrections through the field controller or another compatible internet-connected Android device. This allows the rover to be used with an NTRIP or CORS network when a local base station is not required.

No. The receiver does not contain an internal cellular modem. For NTRIP corrections, internet access is normally supplied through the E600 field controller, a compatible Android device or a mobile hotspot.

Yes. The set includes the rugged FJD E600 field controller for configuring the receivers, managing survey projects, collecting points and completing stakeout work. Customers should review the product package list to confirm all included poles, tripods, brackets, chargers and accessories.

The system works with the FJD Trion Survey application. The software supports receiver configuration, point surveys, line stakeout, road stakeout, DTM stakeout, CAD stakeout, CAD editing and other common field-survey workflows.

Yes. Survey projects and coordinate data can be transferred through the field software using supported file and data formats. The exact import and export options depend on the installed Trion Survey software version and the required CAD or survey workflow.

Each receiver has an integrated 6,500 mAh battery. Typical operation is specified at up to 15 hours in rover mode and up to 10 hours in base mode. Runtime can vary with radio power, temperature, satellite tracking, update rate and battery condition.

Yes. The receiver supports 30 W USB Power Delivery charging and can also accept 9–32 V DC through its aviation connector. This makes it possible to power the base externally during longer surveying sessions when a suitable power source and cable are used.

Yes. The receivers have an IP67 protection rating and are designed for dusty, wet and demanding outdoor environments. Their specified operating temperature range is -30°C to +60°C, but connectors should still be kept properly sealed and the equipment should be handled according to the manufacturer’s instructions.

Each FJD Trion V1t receiver includes 32 GB of internal storage. This can be used for recording raw observation data and other positioning information required for fieldwork or post-processing.
