TL;DR: In this paper, a ground control point based procedure was developed to recalibrate the offsets of the attitude data since they usually are given as relative angles, which theoretically allows sub-pixel accuracy even in steep terrain.

TL;DR: APEX is a dispersive pushbroom imaging spectrometer operating in the spectral range between 380 - 2500 nm as discussed by the authors. But the spectral resolution will not be better than 10 nm in SWIR and < 5 nm in the VNIR range of the solar reflected range.

TL;DR: In this paper, the authors present the laboratory instrumentation and measurements that were brought into place at the German Aerospace Research Establishment (DLR) to calibrate the DAIS 7915 sensor.

TL;DR: APEX (Airborne Prism EXperiment) is a project of the European Space Agency ESA focusing on high accuracy simulation, calibration, and validation for spaceborne remote sensing instruments as discussed by the authors, which comprises a hyperspectral imager for various standard airborne platforms, a fixed installed calibration home base and a complete facility for data processing and archiving.

TL;DR: In this article, two different normalization methods to derive anisotropy factors, i.e., dividing by nadir reflectance and by spectral albedo, are tested and discussed.
