【摘要】：針對(duì)北斗三頻信號(hào),引入了慣性信息輔助周跳探測(cè)與修復(fù),建立了北斗/INS松組合模型,提高了多徑誤差嚴(yán)重影響下的BDS周跳探測(cè)成功率和修復(fù)率。在常規(guī)偽距-相位組合與幾何無(wú)關(guān)組合探測(cè)三頻周跳的基礎(chǔ)上,提出了INS定位輔助的北斗三頻組合法,構(gòu)建了INS輔助的周跳決策量,分析了INS定位誤差對(duì)周跳探測(cè)的影響。該方法克服了周跳探測(cè)受偽距觀測(cè)值精度影響的不足,實(shí)現(xiàn)了北斗系統(tǒng)多徑環(huán)境中的小周跳探測(cè)。試驗(yàn)采用船載INS/BDS三頻組合系統(tǒng)進(jìn)行數(shù)據(jù)實(shí)測(cè)分析,結(jié)果表明,在水面強(qiáng)多徑噪聲環(huán)境導(dǎo)致傳統(tǒng)三頻探測(cè)模型失效的情況下,該方法顯著提高了探測(cè)成功率與修復(fù)率,并適用于低頻北斗觀測(cè)數(shù)據(jù)。
[Abstract]:Aiming at Beidou three-frequency signal, the inertial information is introduced to assist cycle slip detection and repair, and a Beidou / ins combination model is established, which improves the success rate and repair rate of BDS cycle slip detection under the serious influence of multipath error. Based on the conventional pseudo-range-phase combination and geometric independent combination, the Beidou three-frequency combination method for INS location-assisted detection is proposed. The INS assisted cycle slip decision quantity is constructed, and the influence of INS positioning error on cycle slip detection is analyzed. This method overcomes the shortcoming that the cycle slip detection is influenced by the precision of pseudo-range observation value, and realizes the small cycle slip detection in the multi-path environment of Beidou system. The experimental results show that the method improves the detection success rate and repair rate significantly when the traditional three-frequency detection model fails due to the strong multi-path noise on the surface of the water, using the shipborne INS/BDS three-frequency combination system. And suitable for low frequency Beidou observation data.
