PRISM On-Orbit Geometric Calibration and DSM Performance
IEEE Transactions on Geoscience and Remote Sensing, 2009The Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) carried by the Advanced Land-Observing Satellite was designed to generate worldwide topographic data with its high-resolution and stereoscopic observation. For this objective, the on-orbit geometric performance of PRISM sensors has been widely assessed and calibrated since the launch

On-orbit calibration of the SPDM force-moment sensor
Proceedings 2000 ICRA. Millennium Conference. IEEE International Conference on Robotics and Automation. Symposia Proceedings (Cat. No.00CH37065), 2002A six-axes force/moment sensor can be completely characterized by a 6/spl times/6 gain matrix whose elements can be estimated from a sequence of sensor outputs and applied forces. Unlike the conventional calibration procedure that uses an external hardware to produce the load forces, we present a calibration procedure that applies inertial forces as a ...

Star sensor on-orbit calibration based on multiple calibration targets
2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI), 2019The on-orbit calibration is significant for improving the accuracy of the star sensor. The conventional on-orbit calibration methods only use the angular distance between stars as the calibration target. In this paper, according to the idea of information fusion, two calibration targets, which are the singular value and the eigenvalue sensitivity ...

In-Orbit Geometric Calibration of Firebird’s Infrared Line Cameras
2020The German Aerospace Center (DLR) has developed and launched two small satellites (TET-1 and BIROS) as part of the FireBIRD mission. Both are capable to detect and observe fire related high temperature events (HTE) from space with infrared cameras. To enable a quick localization of the fires direct georeferencing of the images is required.

SMOS In-Orbit External Calibration and Validation
PIERS Online, 2005SMOS is ESA’s second Earth Explorer mission with the objective of producing global maps of Soil Moisture and Ocean Salinity over the Earth. The launch date is expected in September 2007. The only instrument on-board SMOS is an L-band Microwave Imaging Radiometer with Aperture Synthesis (MIRAS).

Autonomous on-orbit calibration of a star tracker
2016 IEEE Metrology for Aerospace (MetroAeroSpace), 2016The accuracy of satellite attitude determination depends on the performance of star trackers, which can be improved by careful calibration. Star trackers are initially calibrated on ground. After the launch, because of vibrations, vacuum, thermal cycling and instrument aging, it is common to observe small shifts in calibration parameters.

CryoSat/SIRAL Cal1 Calibration Orbits
2017The main payload of CryoSat is a Ku band pulse-limited radar altimeter, called SIRAL, that transmits phase coherent pulses at a high Pulse Repetition Frequency allowing SAR processing to improve along-track resolution. Being a phase coherent altimeter, SIRAL calibration includes not only corrections for transfer function, gain and instrument path delay
