• Range from 1 meter to 400 meter to a white target
• Repetition rate 1000 measurements in one sec.
• Single shot accuracy better than 10 cm
• Averaged repeatability about 1-5 cm
• 200 mm beam diameter at 100 meter altitude
• Last pulse logic for better penetration of vegetation .On and off are selected by software
• Solid state laser diode with typical over 20 000 hours lifetime
• IR laser at 905 nm giving laser safety class 1 at over 25 meter in distance
• Many units in operation since 4 years

The system is very robust and rugged and sealed to IP 65 level . ( Water proof ). The casing is machined out of a solid piece of aluminum and anodized. Under the bottom there is two mounting threads. This makes the installation simple in the aircraft.

This system is also a part of a laser scanner in some of our products like the GeoMapper and LineMapper solution. Here we have the chance to scan the terrain for measuring the profile of height under the aircraft. This admits new ways for height control and altimetry. Pls. see special data sheets of the geomatic related products.
