BDS三频非差周跳探测与修复

通过比较伪距/载波组合与相位组合阶段取整两种方法在考虑电离层延迟下的综合噪声，选择噪声最小的组合(1,－3,2)、系数之和不为0时噪声最小的组合(4,－3,－2)以及组合(0,1,－1)对北斗三频周跳进行探测与修复。使用IGMAS提供的BDS三频数据，针对BDS 3种不同星座分别进行分析比较，验证了此方法可实时准确探测出非差的各类大小周跳。

BDS Triple-Frequency Undifferenced Cycle Slip Detection and Correction

This paper compares the comprehensive noise of code-phase combination and phase integer, which considers ionospheric delay, choosing the minimum noise combination (1,－3,2) and the combination (4,－3,－2),in which the sum of coefficient is unequal to zero. It combines the combination of (0,1,－1) to detect and correct BDS triple-frequency cycle slip. Analysis with BDS triple-frequency data provided by IGMAS considers three differenced constellations, which validates the hypothesis that it is possible to detect and correct all kinds of undifferenced cycle slip in real time.
