【摘要】：針對(duì)使用組合觀測(cè)值探測(cè)周跳存在不敏感周跳且難以修復(fù)的問題,研究了三頻周跳探測(cè)與修復(fù)的幾何原理,從幾何角度研究了多個(gè)相位無幾何組合(GF)探測(cè)周跳的異同,以及加入MW組合后的效果,并搜索了相應(yīng)的不敏感周跳。提出了以對(duì)應(yīng)的橫截面積最小為原則選取組合量的方法。經(jīng)北斗三頻實(shí)測(cè)數(shù)據(jù)驗(yàn)證,GF組合的數(shù)量以兩個(gè)為宜,加入MW組合后不敏感周跳進(jìn)一步減少,優(yōu)化選取的兩個(gè)GF組合和MW組合聯(lián)合探測(cè)周跳僅存在一個(gè)不敏感周跳,且探測(cè)到的周跳均能正確修復(fù)。
[Abstract]:In order to solve the problem of detecting cycle slips insensitive and difficult to repair using combined observations, the geometric principle of detecting and repairing cycle slips with three frequencies is studied, and the similarities and differences of detecting cycle slips without geometric combination of phases are studied from the geometric point of view.And the effect of adding MW combination, and search the corresponding insensitive cycle jump.In this paper, a method of selecting combinatorial quantities based on the principle of minimum cross-sectional area is put forward.According to the measured data of Beidou three frequency, it is proved that the number of GF combination is better than two, and the insensitive cycle slip is further reduced after adding MW combination, and only one insensitive cycle slip exists in the optimized selection of two GF combinations and MW combination to detect cycle slip.And the detected cycle slip can be repaired correctly.
