With global star map, DSS-14 is for testing all function and performance of the star tracker @ whole global simulator test. DSS-14 is used for testing all function and performance of the star tracker @ the environment experiments such as thermal vacuum and atmospheric thermal cycle. DSS-14 receive the quaternion from the simulator computer and output the real-time star patterns by 422 or UDP connector for the satellite Semi-physical simulation test. Field Of View:20°×20° Magnitude:2 ~ 6.5 Mv Accuracy:30\"[3σ] Update Rate > 40Hz Life Time:3years
