Overview of Dynascan 3D mobile mapper

The Dynascan 3D mobile mapping system is a fully integrated high

speed laser scanner, high accuracy GNSS positioning and Inertial

Navigation System.

Mobile Scanning is a technological advancement on

traditional surveying Traditional Surveying can be:

Hard work

Time Consuming

Costly

Dangerous

Suitable for land and marine applications

Ideal for rugged and dangerous environments

• Fully integrated ‘plug and play’ LiDAR mobile mapping solution

• Rugged and weather proof

• Mass data collection

• Real time results

•Data from all sensors are ‘Time Tagged’ and ‘Geo Referenced’

• Factory calibrated and ‘ready to go’ out of the box

•All Sensors are rigidly mounted in very close proximity to each other

•Reducing potential operator errors on site

• Supplied with a rugged laptop PC & data acquisition software

• Light weight and very portable: (Single Head 17kgs, Dual Head 23kgs)

• Rapidly deployable to mount on any moving platform

• Cost effective

Key features & Benefits

Single scanning system with integrated GPS/

GLONASS, INS and Dual GNSS Antenna heading

system. Accuracy +/-5cm with a 250 meter laser

range capability.

Mapping (M) Grade Systems

Dynascan M250

Dual Scanning laser system with integrated GPS /

GLONASS, INS and Dual GPS Antenna heading

system. Accuracy +/-5cm with a 250 meter laser

range capability.

The systems two lasers are mounted at 45° to

reduce shadow encountered when scanning.

Dynascan M250 X-Plane

Single scanning system with integrated GPS/

GLONASS, INS and Dual GNSS Antenna heading

system. Laser accuracy +/-1cm with a 250 meter

range capability.

Survey (S) Grade Systems

Dynascan S250

Dual Scanning laser system with integrated GPS /

GLONASS, INS and Dual GPS Antenna heading

system. Laser accuracy +/-1cm with a 250 meter

range capability.

The systems two lasers are mounted at 45° to

reduce shadow encountered when scanning.

Dynascan S250 X-Plane

Dynascan HD100

The HD100 is the combination

of the unique Dynascan POD

based concept and Terrestrial

Laser scanning. With a Faro

Focus 3D being integrated into

the current Dynascan POD.

Still very much at concept and

R & D stage with a launch

date proposed to be in Q2

2013
