质子引起的两种具有不同像素尺寸的 CCD 类型的电荷转移效率的变化已被详细描述，并与人造星图像位置偏移的测量结果进行比较，以确定对星跟踪器性能的影响。恒星位置的误差在低背景下很大，但如果背景高并且使用窗口读数，则对于 10 krd(Si) 质子环境（例如 15 年 GEO），可以将误差限制在小于 0.1 像素。
Proton-induced changes in charge transfer efficiency of two CCD types with differing pixel sizes have been characterized in detail and compared with measurements of the shift in position of artificial star images to determine the impact on star tracker performance. Errors in star position are large at low backgrounds but can be limited to less than 0.1 pixels for 10 krd(Si) proton environments (e.g., 15 years GEO) if the background is high and windowed readout is used.
