Citation II s/n 550-0021 is a special mission aircraft equipped with an AVCON dual camera port system. It is a versatile twin-engine jet aircraft modified for acquiring remote sensing imagery including large format aerial photography, as well as data collection for digital cameras, hyper spectral, multispectral, and LIDAR systems.
Standard configuration includes space for two pilots, two equipment operators, and a scientific equipment rack. The aircraft can accommodate additional passengers depending on the amount of scientific equipment. The aircraft's unique side-by-side sensor port modification allows two different sensors to collect data simultaneously. The sensor ports have glass optical flats that allow the cabin to remain pressurized while the camera equipment is installed. Additionally, two high-precision GPS antennas provide signals to user receivers.
This aircraft was primarily used to support the Remote Sensing Division of the National Geodetic Survey, collecting remote sensing data in support of coastal mapping and remote sensing research. Imagery acquired onboard the Citation was used for updating the shoreline and shore features on NOAA's nautical charts. The Citation also served as an emergency responder during hurricane season by collecting digital photography of damaged areas caused by hurricane landfall.
