Notes

• NOTE 1 This error has a spatial periodicity, whose amplitude is defined by the supplier. It ranges from a few pixels up to the full camera FOV.
• NOTE 2 FOV spatial errors are mainly due to optical distortion. These errors can be converted to time domain using sensor angular rate. Then, from temporal frequency point of view, they range from bias to high frequency errors depending on the motion of stars on the detector. They lead to bias error in the case of inertial pointing, while they contribute to random noise for high angular rate missions.
• NOTE 3 The detailed contributors to the FOV spatial error are given in clause 5.5.
