【摘要】：北斗載波相位觀測(cè)值中出現(xiàn)周跳,將嚴(yán)重影響導(dǎo)航定位的精準(zhǔn)性。為了探測(cè)出三頻觀測(cè)數(shù)據(jù)中的周跳特別是小周跳,本文提出超寬巷及小波變換的方法。首先用超寬巷與二階歷元差分構(gòu)造出高靈敏度的周跳檢驗(yàn)量,然后結(jié)合小波變換奇異性探測(cè)原理,對(duì)構(gòu)造出的周跳檢驗(yàn)量進(jìn)行小波分解得到小波系數(shù),根據(jù)小波系數(shù)的模量極大值點(diǎn)探測(cè)并定位周跳,而后將探測(cè)出的周跳值進(jìn)行取整修復(fù)。經(jīng)實(shí)驗(yàn)驗(yàn)證,該方法可構(gòu)造出靈敏度較高的周跳檢驗(yàn)量,并且能有效探測(cè)北斗三頻載波相位中1周的小周跳及1周以下的粗差。
[Abstract]:Cycle slip in Beidou carrier phase observation will seriously affect the accuracy of navigation and positioning. In order to detect the cycle slip, especially the small cycle jump, a method of ultra-wide lane and wavelet transform is proposed in this paper. In this paper, a high sensitivity cycle slip test is constructed by using ultra-wide lane and second order epoch difference, and then wavelet coefficients are obtained by wavelet decomposition of the constructed cycle slip test quantity, which is based on the singularity detection principle of wavelet transform. The cycle slip is detected and located according to the maximum value of the modulus of wavelet coefficient, and then the detected cycle slip is restored by rounding. The experimental results show that this method can construct the cycle slip detection quantity with high sensitivity and can effectively detect the small cycle slip and the gross error of less than one week in the Beidou three-frequency carrier phase.
