摘要: |
针对参考站单站静态双频的特点,提出一种周跳检测与修复的新方法,根据接收机提供的锁定时间信息,综合利用电离层残差和载波相位变化率准确探测并修复周跳。检验证明该方法能够准确可靠地探测并修复失锁 3秒以内的周跳,避免了周跳对载波相位平滑伪距的影响。 |

Detection and Reparation for Cycle Slips Using Ionosphere Residual Error Method and Carrier Phase Rate Method |
|
() |
Abstract: |
A new algorithm for detecting and repairing cycle slips is proposed with single reference station working statically in dual frequency. The parameters of time locked in receiver, ionosphere residual error and carrier phase rate are utilized in this algorithm. This new algorithm can detect and repair cycle slips after loss of lock within 3 seconds so as to avoid the effect of cycle slips on smooth pseudo distance of carrier phase. |
