Topcon LPS Robotic Grader

Robotic total station 3D machine control for fine tolerance grading applications. Topcon LPS is a versatile option that can be installed on any make of grader, dozer, machine attachment and more.

Ideal for projects that have limited GPS availability including tunnels, around tall buildings, under bridges, dense tree coverage and other structures.

  • Forwards and backwards compatible with other Topcon machine control solutions so you can swap between technologies to suit the demands of each project
  • No project too complex with 100% slope control sensor and precision prism measurements
  • Use your robotic instrument for as-built checks and other survey tasks

Topcon LPS solutions are available for sale or for hire from Aptella throughout Australia, Singapore, Philippines and Indonesia.

MM precision with a total station

Topcon’s Local Positioning System (LPS) is ideal for high precision applications where the machine does not have open sky visibility and is unable to receive consistant GPS satellite signals.

Working in built up areas or under heavy tree coverage can limit the performance of GPS-based machine control solutions. Topcon’s LPS system is perfect for these conditions, as it uses a Topcon robotic total station to give positioning corrections to the machine.

Using Topcon’s XTRAC technology, the LPS system tracks the machine at speeds up to 55km/hr! To ensure you meet the fine tolerances required on some projects, machine and blade position is updated 20 times per second.


  • Easy to transfer from GPS to LPS quickly and easily. Simply add a 360° prism to the vibration pole, a radio in the MC-R3 and the total station on a control point and you’re ready!
  • High accuracy for fine tolerance work, with long range 2.4Ghz interference-free radio communications
  • Uses the same GX-60 control box as all other Topcon 3D machine control solutions for maximum flexibility
