Product Line

Two product families covering the workflow from initial survey through to final grade. Mix and match to suit your operation.

FJDynamics · GNSS & Machine Control
FJD

The FJDynamics Trion family delivers centimetre-grade RTK in pocketable, IP67-rated, drop-tested form factors — with IMU tilt compensation that removes the need to level the bubble. Backed by a clean software ecosystem and a full accessory range.

  • Base & Rover KitsTrion V1t Rover and V1tPRO Long-Range Base — full RTK pairs for site survey, set-out and as-builts. V4E series for entry-level and pocket-RTK use.
  • 3D Machine ControlFJD 3D machine control systems for excavators, dozers and graders — full 3D guidance to design surface, driven by GNSS positioning.
  • Field HardwareFJD E600 controllers, D10 rugged tablets, survey poles, bipods, brackets and field cables.
  • SoftwareTrionSurvey for field survey and stake-out, plus Trion Model for desktop point-cloud processing, mapping and 3D modelling.
NST · 2D Laser Machine Control
NST

2D laser machine control systems for civil and earthworks operators — excavator depth control, dozer and grader blade control, and finish-grading for skid steers and loaders. Built around rotating laser transmitters and electro-hydraulic receivers compatible with most makes of excavators, dozers and graders.

  • Excavator & Trenching SystemsBoom and stick-mount laser receivers with in-cab indicators for trenching, footings, drainage and pad excavation to grade.
  • Dozer & Grader Blade ControlBlade-mount receivers with electro-hydraulic control for bulk earthworks, road formation and finish grading.
  • Rotating Laser TransmittersSite-grade self-levelling transmitters for level and slope reference, paired with machine-mount or hand-held receivers.
