The success of the Modular Optoelectronic Scanner MOS on the Indian Remote Sensing Satellite IRS-P3 during the 6 years mission time has been based on its sophisticated in-orbit calibration concept to a large extent. When the internal lamp and the sun

DLR's Modular Optoelectronic Scanner MOS on the Indian Remote Sensing Satellite IRS-P3 has been working now for almost 5 years in orbit. In September 2000 the power supply for driving the internal lamps and the sun calibration equipment failed so tha

Until now incandescent lamp, sun and moon calibrations have been successfully applied for in-flight calibration of spaceborne Earth observation imaging sensors. The performance development of LEDs in the past decade guided to higher luminous efficien

In-orbit calibration is an absolutely necessary and accepted tool to update the pre-flight calibration sets of remote sensing instruments on satellites. Only such a periodical recalibration guarantees the long term quality and accuracy of the data an

Long term orbit missions have the general problem of checking the instrument parameters in order to provide data with a high and equal reliability during the whole mission. Different methods of end-to-end or only partly recalibrations have been used

The Modular Optoelectronic Scanner MOS of the German Aerospace Center (DLR) has now been working about three years on board the INdian Remote Sensing Satellite IRS-P3 very successfully. It consists of three instruments: the spectrometer MOS-A, the sp

The Modular Optoelectronic Scanner MOS was developed at the Institute of Space Sensor Technology/Berlin of the German Aerospace Center (DLR) and specially designed for observations of medium scale effects of the system surface-atmosphere. MOS consist

Imaging spectrometers for the earth observation on unmanned satellites usually work for some years without a chance of direct inspection of their performance data other than by ground-based data evaluation, given and determined during the integration

The recent developments within the ESA funded HRIS (high resolution imaging spectrometer) technology program -- aiming at an airborne demonstrator model -- yielded rather successful subsystem developments. HRIS is designed as a true pushbroom hypersp

The MOS instruments on the Indian satellite IRS-P3 are now working for one year in orbit. Beside the calibration of the instrument during laboratory experiments the methods and tools of the in-orbit calibration gives a reliable basis for the interpre
