LazerZoneTopcon's Millimeter GPS machine-control system enhances the vertical-measurement capability of its conventional RTK GPS-based systems. The new system supplements the RTK setup with a laser signal (Lazer Zone), which fans out to a depth of 10 meters. A GPS machine with a Lazer Zone sensor, says Topcon, has the potential of attaining "vertical accuracy to within a few millimeters."
