UNMANNED AIRCRAFT SYSTEMS FOR CRYOSAT-2 VALIDATION

摘要

A suite of sensors has been assembled to map surface elevationrnwith fine-resolution from small unmanned aircraftrnsystems (UAS). The sensor package consists of a light detectingrnand ranging (LIDAR) instrument, an inertial measurementrnunit (IMU), a GPS module, and digital still andrnvideo cameras. It has been utilized to map ice sheet topographyrnin Greenland and to measure sea ice freeboardrnand roughness in Fram Strait. Data collected during theserncampaigns illustrate its potential to compliment ongoingrnCryoSat-2 (CS-2) calibration and validation efforts.
