摘要：This paper describes the geometric inflight calibration of the Modular Optoelectronic Multispectral Scanner MOMS-2P, whichis collecting digital multispectral and threefold along track stereoscopic imagery of the earth's surface from the PRIRODAmodule of the Russian space station MIR since October 1996. Goal is the verification and, if necessary, the update of thecalibration data, which were deduced from the geometric laboratory calibration. The paper is subdivided into two parts,describing two different procedures of geometric inflight calibration: The first method is based on DLR matching software andis restricted to nadir looking channels, which are read out sim ulta neously. From very many individual point matches betweenthe images of the same area taken by the different CCD arrays the most reliable ones are specially subselected and used tocalculate shifts with components in and across flight direction between the CCD arrays. These actual shifts are comparedto the nominal shifts, derived from the results of the laboratory ca libration , and parameters of the va lid camera model areestimated from both data sets by' least squares adjustment. A special case of band to band registration are the two opticallycombined CCD-arrays of the high resolution channels. They are read out simu ltaneously with a nominal 10 pixel overlapin stereoscopic imaging mode A. The DLR matching software is appl ied to calculate the displacement vector between thetwo CCD-arrays. The second method is based on combined photogrammetric bundle adjustment using an adapted functionalmodel for the reconstruction of the interior orientation . It requi res precise and rel ia ble ground control information as wellas navigation data of the navigation-package MOMSNAV. 11 subsequent image scenes of MOMS-2P data take T083C areevaluated, which were taken in March 1997 bui lding an about 550 km long strip over southern Germany and Austria. Fromboth procedures ca libration data are deduced, which are presented and compared to the la b-ca li bration resu lts.
