New camera systems (metric and non-metric) continue to appear on the market, each time improvements to the technology and competitive pricing. This is the case with the metric medium format camera system iXU-RS1900 from Phase One.  With the purpose of understanding the advancements to the technology, exploring the extent of the capabilities, and to understand the performance of the camera in the field, the camera system was Photogrammetrically calibrated as detailed below.  The results are camera parameters and system parameters calibrated in working conditions in addition to the ones derived in the calibration lab. To accomplish this, the camera was flown at a two GSDs (5 cm and 15 cm) in two transverse flights with each strip flown in forward and reverse directions. This enabled the separation of the effect of GPS shift and the image movement due to shutter speed. The two flying heights permitted a focal length calibration usable for future flights of the camera with GSDs within this interval. The transverse flights cancelled, or minimized, the correlation between linear and angular exterior orientation parameters permitting the determination of fully independent misalignment and shifts. The boresight has an area of (~7 sq. miles) with (27) GCPs that have been measured with ± 1 cm. The individual steps of the calibration and mathematical derivations employed are shown along with corresponding intermediate results that have been statistically checked. Finally, the achieved results (with corresponding statistics) are compared to the Photogrammetric calibration values obtained by similar exercises carried out by the authors with other large format sensors
