Abstract
The Queensland corner reflector array is increasingly being used as a globally unique calibration and validation infrastructure for orbiting Synthetic Aperture Radar sensors. In May and June 2018, Geoscience Australia undertook field survey work at all 40 corner reflector sites to compute a more accurate determination of the position of the corner reflector apex point. This Geoscience Australia Record describes the design and procedure of the field surveys, and the data processing undertaken to arrive at new positions and associated uncertainties for each corner reflector apex point. The positions we report here supersede those that were previously published by Garthwaite et al. (2015a). We also report here the orientation of each corner reflector (at the time of survey) calculated from the new survey observations. We find that the corner reflector orientations (i.e. azimuth and elevation of the corner reflector boresight) are within 2 degrees of the values used during post-installation alignment in 2014.
