AB  - A novel hyperspectral measurement system forunmanned aerial vehicles (UAVs) in the visible to near infrared(VIS/NIR) range (350–800 nm) was developed based on theOcean Optics STS microspectrometer. The ultralight device relieson small open source electronics and weighs a ready-to-fly216 g. The airborne spectrometer is wirelessly synchronized toa second spectrometer on the ground for simultaneous whitereference collection. In this paper, the performance of thesystem is investigated and specific issues such as dark currentcorrection or second order effects are addressed. Full widthat half maximum was between 2.4 and 3.0 nm depending onthe spectral band. The functional system was tested in flightat a 10-m altitude against a current field spectroscopy goldstandard device Analytical Spectral Devices Field Spec 4 overan agricultural site. A highly significant correlation (r2 > 0.99)was found in reflection comparing both measurement approaches.Furthermore, the aerial measurements have a six times smallerstandard deviation than the hand held measurements. Thus, thepresent spectrometer opens a possibility for low-cost but highprecisionfield spectroscopy from UAVs.
