The expressions of Active Pixel Sensor(APS) detected star signal and APS noise were given
and Signal-noise Ratio (SNR) of star sensor was obtained. Based on the theory of inspecting signal from noise and optimal SNR threshold detection principle
the detection sensitivity model was established
and the corresponding APS star sensor detection limit was obtained based on APS IBIS5 and general optical system parameter.
