【摘要】：隨著北斗衛(wèi)星導(dǎo)航系統(tǒng)的發(fā)展日益成熟,開(kāi)發(fā)基于北斗的星基增強(qiáng)系統(tǒng)已刻不容緩,而電離層誤差是影響星基增強(qiáng)系統(tǒng)定位精度的重要誤差源。利用中國(guó)大陸構(gòu)造環(huán)境監(jiān)測(cè)網(wǎng)絡(luò)的10個(gè)GNSS參考站在2016年3月20日的觀測(cè)數(shù)據(jù),驗(yàn)證了基于北斗導(dǎo)航系統(tǒng)的星基增強(qiáng)系統(tǒng)格網(wǎng)電離層修正算法在中國(guó)地區(qū)部分站點(diǎn)的修正精度,與Klobuchar模型修正法進(jìn)行了對(duì)比,并檢驗(yàn)了格網(wǎng)電離層垂直延遲的修正誤差GIVE。結(jié)果表明,格網(wǎng)電離層修正算法的修正精度普遍優(yōu)于Klobuchar模型修正法;修正誤差也在正常范圍內(nèi),進(jìn)一步說(shuō)明格網(wǎng)電離層延遲算法在中國(guó)地區(qū)的應(yīng)用是可行的。
[Abstract]:With the development of Beidou satellite navigation system, it is urgent to develop the beidou satellite based augmentation system, and the ionospheric error is an important error source that affects the positioning accuracy of the satellite based augmentation system. Based on the observation data of 10 GNSS reference stations in the mainland of China on March 20, 2016, the accuracy of the ionospheric correction algorithm for space-based augmentation system based on Beidou navigation system is verified in some stations in China. Compared with the Klobuchar model correction method, the correction error GIVE. of grid ionospheric vertical delay is tested. The results show that the correction accuracy of the grid ionospheric correction algorithm is generally superior to that of the Klobuchar model correction method, and the correction error is within the normal range, which further shows that the grid ionospheric delay algorithm is feasible in China.
