关键词	Detection sensitivity is an important parameter of star tracker which can express detection limit of the weakest detected visual star magnitude. Detection sensitivity of APS star tracker is related to APS parameters optical system aperture and lens permeance rate SNR and so on. This paper the expressions of APS star detected signal and APS noise are given so signal-noise ratio (SNR) of star tracker can be obtained. And based on the theory inspecting signal from noise and optimal SNR threshold detection principle the detection sensitivity model can be obtained. The corresponding APS star tracker detection limit is obtain based on APS IBIS5 and general optical system parameter design. When SNR threshold is 8.1 which can obtain 99.9% detection probability we can calculate that the detection sensitivity is 6.5 visual magnitude.
