Control Methods
The following sections describe the four types of control possible
with the mmGPS 3D Paver: mmGPS, slope, sonic, and laser.
mmGPS Control
mmGPS uses Topcon’s unique LazerZone™ technology to produce
millimeter accuracy. LazerZone technology combines 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 (Figure 5-16).
• The PZL-1 laser transmitter emits a unique laser beam that
provides a working range up to 2000ft (600m).
• The PZS-MC laser sensor and GPS receiver at the machine
detects the laser beam and satellite signals, sending millimeter
accurate positioning data to the control box for correction control.
• The PZS-1 sensor and GPS receiver detects the laser beam and
satellite signals, providing millimeter accurate spot-checks
throughout the jobsite.
