1 引言高精度的GPS定位和导航要求在数据预处理阶段正确修正载波相位观测量中所包含的跳周。仅一二个周期的跳变所引起的测量偏差就使厘米级的定位和导航难以实现。过去十几年内,研究人员已经开发了多种检测和修正跳周的方法。然而,常常仍有一二个跳周不能检测和正确修正,需要分析人员参与,才能完成数据处理,因此,一个操作性能完善的自动化GPS数据预处理器仍是我们可望而不可及的目标。尽管这样,我的 1 INTRODUCTION High-precision GPS positioning and navigation requires that the jump weeks contained in the carrier phase observations be correctly corrected during the data preprocessing phase. Measurement errors caused by only one or two cycles of jump make CMM positioning and navigation difficult to achieve. In the past decade or so, researchers have developed a variety of methods to detect and correct jumps. However, there are often still one or two skip cycles that can not be detected and correctly corrected and require the participation of analysts to complete the data processing. Therefore, a fully automated GPS data preprocessor is still beyond our reach. In spite of this, mine
