RIEGL LMS-Q780

RIEGL Laser Measurement Systems has launched the new long range airborne laser scanner LMS-Q780. With an operating flight altitude of up to 10,000 ft at 100 kHz laser pulse repetition rate (PRR) it opens new perspectives in airborne laser scanning.    
The laser wavelength qualifies the scanner for glacier and snowfield mapping, its digital waveform processing capabilities for high-altitude topographic mapping.

Unique features of this instrument include the automated resolution of range ambiguities, typically occurring at large measurement ranges and high repetition rates. Peter Rieger, Product Manager Airborne Laser Scanning: “The effect of range ambiguities appearing in airborne laser scanning is known as “multiple-time-around” or “multiple-pulses-in-the-air”.

Up to now it was necessary to carefully consider the appearance of range ambiguities during flight planning by choosing a flight altitude above ground assuring that all range measurements stay within a single MTA zone – which may be a really difficult task especially in complex terrain like mountainous areas. RIEGL’s new generation of airborne laser scanners overcome this limitation by multiple-time-around (MTA) processing.”
