Proceedings PaperOn-orbit determination of focal plane detector positions
|Format||Member Price||Non-Member Price|
Post launch tests on the GOES satellite cameras called for determination of the positions of various imaging detectors. The GOES spacecraft's two cameras, the imager and sounder, are both scanners that use focal plane arrays. The below method determines their detectors' relative positions by recording detector outputs as the edge of the moon drifts past their instantaneous fields of view. While this method works well with simulated data, it is still experimental and is still being tested with flight data.
