| Abstract: | An novel analysis method of line-of-sight(LOS) measurement error of multiple factors is proposed for the space-based optical sensor.A measurement model is established using the transformation from target position to focal plane.Each error source of the line-of-sight error is analyzed.The formulas among line-of-sight measurement error in earth centered inertial coordination and satellite orbit error,satellite attitude error,sensor pointing error,instantaneous field of view of the sensor are derived.The effic... |
