Millimeter GPS™ only works with Topcon GPS+ systems and can be added anytime in the future. To get millimeter accurate GPS when you need it, get Topcon GPS+ today!

Featuring Topcon's revolutionary Lazer Zone™ technology, the next generation of laser measuring equipment, Millimeter GPS™ is the most exciting job site technology since the arrival of automated machine control, the robotic total station, or the rotating laser! Get all the benefits of existing technologies in one high precision job site control system:

• World's first millimeter accurate GPS system – up to 300% more accurate than standard GPS!
• Lazer Zone™ transmitter provides wide vertical measurement area – 600m/2000ft diameter, 10m/33ft height
• Multiple rover support (machine or pole mounted)
• Works with existing Topcon GPS+ systems

Lazer Zone™: Where Precision and Productivity Merge

At the heart of the Millimeter GPS™ system is Topcon's Lazer Zone™ technology. This revolutionary system brings together the simplicity of a rotating laser, the accuracy of a robotic total station, and the flexibility and multiple user capabilities of GPS, into one complete jobsite solution!

PZL-1 Positioning Zone Laser Transmitter

Operates similar to a standard rotating laser, but transmits a unique Lazer Zone™ signal to provide a working range of 2000ft! Instead of a traditional flat plane, the PZL-1 provides an incredible measuring area of 33ft in height! You can even link up to four laser transmitters for use on large sites to cover a distance of nearly 8000ft with elevation changes of over 130ft!

No more taking time out to reposition your laser. With the PZL-1, multiple rovers can use the same transmitter, even at different elevations for continuous production!

PZS-1 Positioning Zone Sensor for Mobile Rover Applications

Instantly computes precise vertical information from the PZL-1 laser transmitter. Using Lazer Zone™ technology, the PZS-1 automatically determines elevation based on your job site control, so there's no need for a moveable mast or grade rod.

Mount the PZS-1 to your range pole, where it receives the PZL-1 laser signal and wirelessly transmits data to your existing HiPer rover!

PZS-MC Positioning Zone Sensor for Machine Control Applications

Mount the PZS-MC to your grader or dozer to replace your machine-mounted GPS antenna and benefit from Lazer Zone technology. The PZL-1 transmitter can operate multiple PZS-MC equipped machines, providing continuous, high-speed, high-precision control throughout the job site!

The smart Lazer Zone™ technology can distinguish signals from different transmitters for hassle-free, precision grading.

The Millimeter GPS™ Solution

Combine Lazer Zone™ with GPS to take your job site to the next level: Millimeter GPS™. Topcon's innovative Millimeter GPS system computes precision coordinates from GPS+ satellites so you can operate multiple rover units from just one GPS and Lazer Zone base system. The results are productivity and job quality in a zone by themselves!

Millimeter GPS™ is a step ahead of traditional sonic control or localized GPS systems that were often labor intensive with the ability to control only one machine at a time. Simply set up your Topcon RTK GPS+ system as usual, add a wireless PZS-1 sensor to your mobile rover, and set up the PZL-1 transmitter to get instant millimeter accurate elevations anywhere in the Lazer Zone! This simple addition to your existing 3D-GPS system is the perfect solution for high-precision jobs, even those with large elevation changes!
