【摘要】：中國(guó)大陸構(gòu)造環(huán)境監(jiān)測(cè)網(wǎng)絡(luò)由260個(gè)連續(xù)全球定位系統(tǒng)觀測(cè)站點(diǎn)和2 000個(gè)不定期全球定位系統(tǒng)觀測(cè)站點(diǎn)構(gòu)成,一般采用GAMIT或Bernese高精度數(shù)據(jù)處理軟件進(jìn)行處理。由于GAMIT及Bernese軟件對(duì)測(cè)站數(shù)處理能力的限制,必須對(duì)陸態(tài)網(wǎng)連續(xù)運(yùn)行基準(zhǔn)站進(jìn)行分區(qū)解算。針對(duì)這一問(wèn)題,為研究不同分區(qū)方案對(duì)陸態(tài)網(wǎng)解算精度的影響,該文基于全國(guó)55個(gè)陸態(tài)網(wǎng)絡(luò)連續(xù)運(yùn)行基準(zhǔn)站數(shù)據(jù),采用整網(wǎng)解算方案以及間距分區(qū)法和區(qū)域子網(wǎng)劃分法分別進(jìn)行解算,并以整網(wǎng)解算結(jié)果作為標(biāo)準(zhǔn)值,對(duì)比兩種分區(qū)方案與整網(wǎng)解算方案的基線長(zhǎng)度差及坐標(biāo)差。結(jié)果表明,間距分區(qū)方案解算精度比區(qū)域子網(wǎng)劃分方案精度高,可實(shí)現(xiàn)對(duì)陸態(tài)網(wǎng)分區(qū)的高精度解算。最后利用間距分區(qū)法對(duì)全國(guó)240個(gè)陸態(tài)網(wǎng)絡(luò)連續(xù)運(yùn)行基準(zhǔn)站進(jìn)行分區(qū)解算,得到了較高精度的解算結(jié)果。
[Abstract]:The tectonic environment monitoring network in China consists of 260 continuous GPS observation stations and 2 000 irregular GPS observation stations, which are generally processed by GAMIT or Bernese high-precision data processing software. Due to the limitation of GAMIT and Bernese software on the number of stations, it is necessary to calculate the land network continuous operation reference stations. To solve this problem, in order to study the influence of different zoning schemes on the calculation accuracy of land state network, this paper is based on the data of 55 continuous operation reference stations of land state network in China. The whole network solution scheme, the interval partition method and the area subnet partition method are used to solve the problem, and the results of the whole network solution are taken as the standard values to compare the baseline length difference and coordinate difference between the two partition schemes and the whole network solution scheme. The results show that the resolution accuracy of the spaced partition scheme is higher than that of the regional subnet partition scheme. Finally, the method of spacing partition is used to calculate 240 land network continuous operation reference stations in China, and the results are obtained with high accuracy.
