摘要
利用联合伪距相位组合法以及无几何相位法进行北斗三频数据的周跳探测与修复,通过构造2个伪距相位组合(0,-1,1),(1,4,-5)以及1个无几何相位组合(1,1,-2)共3个线性无关的周跳检测量,对实测北斗三频数据进行周跳探测实验,并采用最小2范数法修复周跳。结果表明:无论是高采样率数据还是低采样率数据,文中提出的方法均可探测出包括1周在内的所有周跳组合,且不存在不敏感周跳组合。
This paper presents cycle-slip detection and repair for Beidou triple-frequency data with code-phase combination and geometry-free phase combination.Through the composition of the three linearly independent combinations,(0,-1,1),(1,4,-5),(1,1,-2),this paper uses observation data to conduct cycle-slip detection and repair experiment and takes the minimum 2 norm as the cycle-slip repair principle.The result shows that it is accurate to detect and repair any cycle-slip combination of observation data in different sampling rates and there is no existing insensitive cycle-slip combination.
