  • High accuracy grade reference covers entire project – eliminates string-line
  • Provides precise vertical measurement for multiple machines and grade checkers
  • Use up to four transmitters to extend work area
  • Pave transitions, even through horizontal and vertical curves
  • Works with existing Topcon GPS+ systems

Topcon’s Millimeter GPS Paver System is the World’s First GPS based millimeter accurate control for pavers. Topcon’s revolutionary Lazer ZoneTM technology based, Millimeter GPS uses GPS positioning together with a zone laser reference to give you unparalleled freedom and productivity. It also provides the flexibility to mix-and-match sensors to best meet the requirements of each job and the way you want to work.

Field proven components - proven to perform

Topcon’s Millimeter GPS Paver System combines the field proven components of Paver System Five with the rugged, high-accuracy Millimeter GPS instruments and sensors. Mounted on the paver is the operator’s interface to Millimeter GPS Paver System, the GX-60 control box. Able to control the two tow point cylinders independently the GX-60’s color, graphical screen displays machine position on the job, and the sensors being used to control the left and right side of the screed, and current elevation and slope.

Topcon’s MC-R3 is the control center of Topcon’s 3D GPS+ system. Providing either solid brackets for permanent mounting or magnetic mounting for portability, the MC-R3 contains all of the GPS receivers, radios, and controllers in a single “built to last” housing. A built-in MINTER panel provides status lights and function keys for easy performance verification and system checks. The MC-R3 also features an Ethernet port, increased processing power over the previous generation box, and additional valve drivers to account for the widest array of machine compatibility.

Topcon’s PZS-MC Positioning Zone laser receiver with integrated GPS+ antenna is mounted to the tow arm on the left or right side of the paver.

Customize Millimeter GPS to fit any job

Combine Millimeter GPS with Topcon’s slope sensor for road, highway, or runway paving. Or use the patented Sonic Tracker II® for joint matching jobs like curb and gutter, or parking lots. The choice is yours, the flexibility of Topcon’s Millimeter GPS makes it easy.

Lazer Zone™ – the heart of Millimeter GPS

Topcon’s PZL-1 with revolutionary Lazer ZoneTM Technology operates similar to a standard rotating laser, transmitting a unique laser signal. Unlike a standard rotating laser that can only work in a flat plane, the PZL-1 transmits a revolutionary Lazer ZoneTM signal that creates a measuring area 10 meters (33 feet) in height!

Positioned anywhere within the “Laser Zone”, Millimeter GPS Paver System’s PZS-MC sensor instantly computes precise vertical information. No need to incorporate a moveable mast, the Lazer ZoneTM Technology determines its elevation automatically. Even if your site has an elevation variance of 10 meters (33 feet), you never have to reposition your instrument or receivers!

For sites with significant elevations or large areas, up to four PZL-1 Lazer ZoneTM transmitters can be “linked” to cover a larger area and elevation change of over 130 feet!

Like a rotating laser, Lazer Zone supports multiple users. Using a PZS-1 sensor and Topcon’s FC-200 field controller on a grade rod, basic surveying tasks and grade checking are a snap. In situations where multiple PZL-1 transmitters are being used, each can be set to one of four signal channels. The system will transition seamlessly from transmitter to transmitter without disruption.
