MM accuracy using GPS+ positioning

Millimetre GPS+ is the perfect tool for fine tolerance work, combining the advantages of laser precision with GPS and GLONASS. This patented Topcon technology improves grading accuracy up to 300% over existing 3D-GPS machine control systems. Topcon recently released the latest generation of laser transmitter for use with its millimetre GPS positioning system – the LZ-T5.

Replacing the PZL-1, the LZ-T5 uses patented zone-beam laser technology, providing continuous high accuracy elevation information to improve GNSS positioning.

The LZ-T5 incorporates new design and operational features, including extended battery life, a new ergonomic design and enhanced performance even in fluctuating weather conditions.

Simply add the LZ-T5 to your existing GPS+ system and watch your vertical accuracy shrink down to numbers you never thought possible.
