The first equipment to be integrated in WATERHYPERNET is the PANTHYR (“PAN-and-Tilt HYperspectral Radiometer”) system described by [Vansteenwegen et al, 2019]. The PANTHYR system consists of two TRIOS-RAMSES hyperspectral radiometers (one radiance, one irradiance), covering the wavekength range 400-900nm, mounted on a FLIR PTU-D48 pan-tilt unit and controlled by purpose-made electronics and software. Auxiliary equipment includes a GNSS receiver, a 4G router and antenna and a simple RGB camera for water and sky images as well as enclosures, mechanical brackets, cabling and site-specific power supply and mechanical fixtures.
A second radiometer, for future inclusion in the WATERHYPERNET, is under development by the H2020/HYPERNETS consortium. The HYPERNETS project is funded by the European Union’s Horizon 2020 research and innovation program under grant agreement No 775983.
HYPSTAR® is an autonomous hyperspectral radiometer system designed for surface reflectance validation of optical satellite data products. HYPSTAR captures radiance and irradiance measurements.
A HYPSTAR system consists of a hyperspectral VNIR spectrometer, an optional SWIR spectrometer, and a simple RGB imaging camera alongside the hyperspectral measurements. It also includes an LED source for calibration monitoring, a pan-tilt mechanism, auxiliary sensors (pressure, humidity, temperature, rain, light, two external cameras), and a standardised data stream for easy and systematic exploitation by downstream validation networks WATERHYPERNET and LANDHYPERNET.
