Sažetak
Sound title actually notes the utilization of hyperspectral imaging using airborne platform for the first time in Croatia. Specific application requirements highlited the need for Position and Orientation system capable to measure and record inertial orientation and GPS position data at high frequency, according to general requirement for line imaging mode utilization of airborne hyperspectral imaging scanner, which states that at least one set of position and orientation data should be available for each scan line. GPS proved as critical throughout few different tasks it has in: velocity and heading aiding for IMU (drift correction), time synchronization, trigerring and navigation. Furthermore, several electro-optical sensors were integrated in airborne sensor pod, with hyperspectral puhbroom scanner and hybrid IMU/GPS system (serving as Position and Orientation System) in its core. Complete airborne multisensor system is built off-the-shelf, integrated by using PC running under Windows OS and aimed to different applications, such as spectral detection of oil polution spill at sea, quality monitoring of water in lakes and rivers and explosives polution detection at military fire range, etc. Good understanding of different application requirements, along with the characteristics and design specification of state of the art sensors, led to system integration, which has proved as operational during first flight tests and has already scheduled for airborne mapping campaignes over mine contaminated area in Croatia.
