摘要
在单频单历元GPS短基线定向中,由于模糊度解的不可靠性,导致部分定向结果不可靠。在基线约束GPS短基线定向算法的基础上,提出一种动态准实时定向滤波算法。该算法根据载体的运动特性,判断并剔除解算错误的值,并在解算错误或解算失败的历元进行插值。实测数据处理表明,该方法能够将基线约束算法的定向正确率提高5～10%左右,使基线约束GPS短基线定向算法的稳定性得到进一步提高。
On the basis of baseline length constraint orientation algorithm, a dynamic quasi real-time smoothing algorithm, which take consider of baseline body’s dynamic character, was put forward to improve the solution effect of GPS dynamic single epoch orientation with single-frequency receivers. The data analysis in tests showed this method could improve the correct rate of baseline constraint orientation algorithm about 5-10 percent.
