MX2 – Alaska North Slope

MX2 System  Class 1 Laser  Range up to 250m  Accuracy ±1cm  Scanner Field of View 360 °  Scan rate 20Hz at 1800 rpm (single head)  Pulse rate 36KHz (single head)  Power 12 to 36 volts DC  Water & Dust Resistant: IP65  Weight 17Kg (single laser); 23Kg (dual lasers )

Trimble MX2 Workflow Process Vehicle Process Laser + Trajectory: I m age Data: POSPac MMS Trident I m aging Hub Collect Data: • Process vehicle + • Import trajectory base station • Breakline + Center Line Trident Capture • Create DTM • POSView • Export to TBC

MX2 Data Collection  2 Lasers, 6 Cameras  2 Mile test section  Speed of 15 mph  Two passes, one for each side slope  Full coverage without shadowing  250 m plus range  Several pads also collected

MX2 images

Trajectory Post-Processing – POSPac MMS

Accuracy Results  Good GPS conditions, use of CORS, correct collection procedures  RMS absolute accuracy X, Y of 1.2 cm  RMS absolute accuracy Z of 2.0 cm  Results consistent with expectations given collection conditions
