Paper Abstract

Several years ago pushbroom slit and image spectrographs were one kind of most difficult multispectral scanners to realize. Since the microprocessor and CCD-based technology came rapidly up those system are now coming back. Many advantages are combined in these systems such as highest spectral and spatial resolutions, tremendous increase of number of bands to be recorded at the same time, choice of look directions, programmable band sets, real time displays of bandsets during recording, on line calibration and evaluation between recording in the aircraft. Major impacts on these records are drifts and rolls, caused by the aircraft, resulting in visible deviations from the preselected flight line. The deviations cannot be fully corrected during flights, but minimized by keeping the aircraft on its track next to the flight line. Computer controlled flight direction for the pilot or autopilot by GPS/INS with storing the tracking data together with a stabilized platform is an up to date answer.
