基于GPS实测控制点的SPOT51A数据几何校正方法精度比较
SPOT5 GPS 几何校正 正射模型法
2009/11/23
采用高精度的星基差分GPS实测控制点对SPOT 5 1A数据几何校正方法进行比较，对校正误差的产生原因进行分析。结果表
明，正射模型法的校正精度远高于多项式法的校正精度;多项式法在X方向上的误差远大于Y方向上的误差；正射模型法的误差在2个
方向上差别不大。卫星扫描角度引起的像元畸变是多项式方法产生较大误差的重要原因。
星载GPS测量数据周跳探测方法研究
GPS 周跳探测 测量误差
2009/10/23
针对低轨卫星应用星载GPS定轨中载波相位的周跳探测问题，对星载GPS测量数据的误差及其对周跳探测的影响进行了分析，并在此基础上根据星载GPS应用的特点，对TurboEdit数据预处理方法中周跳探测算法进行改进，将周跳探测与测量误差联系起来，实现依据测量误差变化相应地调节周跳探测的判断条件。仿真结果表明即使在测量误差较大的情况下，改进的方法仍然能够对周跳进行有效的探测。
