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.
