【摘要】：針對(duì)北斗衛(wèi)星定位系統(tǒng)(BDS)在載波相位觀測(cè)中出現(xiàn)的周跳問題,建立改進(jìn)的多項(xiàng)式擬合模型對(duì)載波相位觀測(cè)中產(chǎn)生的周跳進(jìn)行探測(cè)與修復(fù)。該方法采用3個(gè)接收機(jī)測(cè)得與同一顆衛(wèi)星間的載波相位觀測(cè)值,同時(shí)結(jié)合接收機(jī)與衛(wèi)星間的載波相位測(cè)出兩組單差值,利用一組單差值進(jìn)行的多項(xiàng)式擬合可獲得產(chǎn)生周跳的歷元數(shù),結(jié)合另一組單差值的多項(xiàng)式擬合可確定哪組載波相位發(fā)生周跳,最后對(duì)周跳進(jìn)行修復(fù)。通過實(shí)驗(yàn)仿真發(fā)現(xiàn),該方法不僅可以測(cè)得0.2以上的周跳,也可以測(cè)出0.2以上的周跳發(fā)生在哪組載波相關(guān)觀測(cè)值中。
[Abstract]:Aiming at the cycle slip problem in carrier phase observation of Beidou Satellite Positioning system (BDS), An improved polynomial fitting model is established to detect and repair the cycle slips generated in carrier phase observation. The carrier phase observations between the same satellite and three receivers are obtained by using this method. At the same time, combining the carrier phase between the receiver and the satellite, two groups of single difference values are obtained, and the number of epochs that generate the cycle slip can be obtained by polynomial fitting with one set of single difference values. Combined with polynomial fitting of another group of single difference values, the cycle slip of carrier phase can be determined, and the cycle slip can be repaired at last. The experimental simulation shows that the method can not only measure the cycle slip above 0.2, It is also possible to determine the group of carrier correlation observations in which the cycle slip above 0.2 occurs.
