EOC researchers have developed a sensor platform that offers space for two imaging spectrometers and an airborne camera system. Among other applications, the platform will be used on two DLR research aircraft. It was successfully tested over the past few weeks on several trial flights over Kaufbeuren, Munich and Brandenburg, and the first research data could be recorded.

The new platform is stabilized and allows optical imaging simultaneously with use of the spectrometers. This means that data from the two systems can be immediately compared and conclusions drawn. Stabilization of the platform and highly precise georeferencing with a new navigation system reduce image distortion and improve data quality.
The imaging spectrometer system consists of two cameras from the Norwegian producer HySpex (VNIR-3000N and SWIR-384). With its spectral measurement range of 400 nm – 2500 nm it covers most of the light emitted by the sun and reflected from Earth's surface. From this data conclusions can be drawn about the land surface (such as the health of plants and trees), substances in water bodies, and atmospheric parameters (methane sources, water vapour). These data will be used to develop new remote sensing methodologies in preparation of future satellite missions (such as CHIME) and for validating current satellite missions (like EnMAP).
The PhaseOne iXM-RS150F industrial camera will be used as the optical sensor. It is already a component of the helicopter-supported 4k/VABENE aerial camera system. At an above-ground flight altitude of 1000 m its 4.2 cm geometrical resolution assures detailed RGB-images for such purposes as assessing states of damage, generating high precision 3D models, and analysing automated driving in traffic research.
