Topcon Positioning Systems” industry-leading Millimeter GPS precise positioning technology has been expanded to include asphalt pavers. The world”s first 3D-GPS + control system for pavers, profilers and trimmers was introduced last year.
The Topcon Millimeter GPS system allows contractors to use one GPS system for finish grading, trimming, profiling, and paving airport, highway and parking lot projects.
Topcon”s unique technology provides a significant enhancement in the vertical measuring precision of RTK GPS. The technology, known as Laser Zone, is used by hundreds of companies worlwide to generate a vertical accuracy to within a few millimeters as compared to the centimeter vertical accuracy of conventional RTK GPS.
Utilized on asphalt pavers, the Millimeter GPS technology incorporates a unique zone- beam laser transmitter, the PZL-1, that sweeps a 2,000 foot diameter (600m) area with a 33-foot (10 m) high wall of laser light. A compact sensor, the PZS-MC, is mounted on a mast which is attached to the toe arm of the paver. Anytime the PZS-MC sensor is positioned within the laser zone signal, the system provides vertical data resulting in millimeter vertical measuring precision.
Millimeter GPS technology is “up to 300 percent more accurate than standard GPS, and will provide the best 3D machine control in the industry,” Murray Lodge, TPS director of sales-construction, said. “The Laser zone technology 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 job site solution,” he said.
