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.

CCD noises and their causes are analyzed. Methods to control these noises  such as Correlated Double Sampling (CDS)  filtering  cooling  clamping  and calibration are proposed. To improve CCD sensor's performances  the IC  called Analog Front End (AFE)  integration of CDS  clamping  Programmable Gain Amplifier (PGA)  offset  and ADC  which can fulfill the CDS and analog-to-digital conversion  is employed to process the output signal of CCD. Based on the noise control approaches  the idea of chip design of linear CCD drive pulse generator and control interface is introduced. The chip designed is playing the role of (1) drive pulse generator  for both CCD and AFE  and (2) interface  helping to analysis and transfer control command and status information between MCU controller and drive pulse generator  or between global control unit in the chip and CCD/AFE. There are 6 function blocks in the chip designed  such as clock generator for CCD and AFE  MCU interface  AFE serial interface  output interface  CCD antiblooming parameter register and global control logic unit. These functions are implemented in a CPLD chip  Xilinx XC2C256-6-VQ100  with 20MHz pixel frequency  and 16-bit high resolution. This chip with the AFE can eliminate CCD noise largely and improve the SNR of CCD camera. At last  the design result is presented.
