RIEGL의 VQ-480II는 이미 그 성능이 널리 입증된 기존 모델 VQ-480에 이어서 성능 및 사용자 편의성을 한단계 더 업그레이드한 항공라이다 시스템입니다.

RIEGL의 그동안 쌓아온 노하우로 성능에 비해 IMU/GNSS를 포함하고도 10kg라는 획기적인 경량을 실현화한 결과 유인 항공기는 물론 무인 기체까지 장착 플랫폼을 확장 시켰습니다.

    1. Rounded average PRR
    2. Typical values for average conditions and average ambient brightness. In bright sunlight, the max. range is shorter than under an overcast sky.
    3. The maximum range is specified for flat targets with size in excess of the laser beam diameter, perpendicular angle of incidence, and for atmospheric visibility of 23 km. Range ambiguities have to be resolved by multiple-time-around processing.
    4. Typical values for max. effective FOV 75°, additional roll angle ± 5°
    5. If more than one target is hit, the total laser transmitter power is split and, accordingly, the achieveable range is reduced.

  • Limitation for range measurement capability, does not consider laser safety issues!
  • Accuracy is the degree of conformity of a measured quantity to its actual (true) value.
  • Precision, also called reproducibility or repeatability, is the degree to which further measurements show the same result.
  • One sigma @ 150 m range under RIEGL test conditions.
  • User selectable.
  • Measured at 1/e2 points, 0.35 mrad corresponds to an increase of 35 mm of beam diameter per 100 m distance.
