摘　　要：根据电离层残差法在周跳探测与修复中的应用原理,提出了历元间相位电离层残差二次差分的方法,解决了采样间隔较大时,周跳探测与修复的精度受电离层延迟误差制约的问题,提高了周跳探测的精度;在进行周跳修复时,利用超宽巷组合代替B2和B3组合,解决了无法修复不敏感周跳的问题。结果表明,对于采样间隔较大、历元间电离层状态不稳的观测值,该组合方法有效地探测出不足1周的周跳值,并能够有效地修复任意周跳组合。In order to solve the problem that the precision of cycle slip detecting and repairing is limited by the ionospheric delay error when the sampling interval is larger, and according to principle of the ionosphere residual method which is used in cycle slip detecting and repairing, a new approach about second-order ionosphere residual method among epochs is proposed.When repairing cycle slip, the method of using ultra wide lane instead of B2 and B3 combination settles a dispute that the combination of insensitive cycle slip can not be repaired. Results show that, when the sampling interval is larger and the state of ionosphere among epochs is instability, the combination method can effectively detect the value of cycle slip less than 1, and can also availably repair cycle slip of any combination.
