Geometric in-flight Calibration of the stereoscopic CCD-Linescanner MOMS-2P

Abstract

This paper describes the geometric inflight-calibration of the Modular Optoelectronic Multispectral Scanner MOMS-2P, which is collecting digital multispectral and threefold along track stereoscopic imagery of the earth´s surface from the PRIRODA module of the Russian space station MIR since September 1996. Goal is the verification and, if necessary, the update of the calibration data, which were deduced from the geometric laboratory calibration. The presented approach is based on combined photogrammetric bundle ajustment using an adapted functional model for the reconstruction of the interior orientation. It requires precise and reliable ground control information as well as navigation data of the navigation-package MOMSNAV. 11 subsequent image scenes of MIR-orbit T083C are evaluated, which were taken in April 1997 building an about 550 km long strip over southern Germany and Austria. In this paper the photogrammetric inflight calibration principle and the preprocessing of the input data are described and first results are presented.
