By using high-resolution reference data to identify accurate GCPs, considering the spacecraft attitude deviations which TBUS can't supply, and adjusting the epoch time and ephemeris data at the criteria of constraint LeastMean-Square-Error, the geolocation accuracy of navigation for AVHRR data can be improved greatly.
由于采用具有足够定位精度的高分辨率参考图象以提取高精度的地面控制点，考虑了TBUS轨道报所不能提供的卫星姿态偏差，对历元时刻和卫星轨道根数进行有约束条件的参数最优调整，可使整条轨道大范围内的AVHRR导航定位精度有较大提高。
