【摘要】：以南寧市軌道交通GPS控制網(wǎng)測量的實際工程作業(yè)為背景,首先對電離層延遲基本模型的建立進行了論述,然后結(jié)合南寧市區(qū)域大氣電離層活動的特點,利用電離層延遲模型和精密數(shù)據(jù)處理軟件對南寧市區(qū)域電離層延遲數(shù)據(jù)進行了解算,并通過與電離層現(xiàn)報數(shù)據(jù)進行比較,分析了南寧市軌道交通GPS控制測量短周期內(nèi)各個測站的電離層延遲變化規(guī)律以及市軌道交通GPS控制網(wǎng)測量的影響。
[Abstract]:Based on the practical engineering work of the GPS control network survey of Nanning rail transit, the establishment of the basic model of ionospheric delay is first discussed, and then the characteristics of the ionospheric activity in Nanning region are combined.By using the ionospheric delay model and precise data processing software, the ionospheric delay data in Nanning city are calculated and compared with the current ionospheric data.The variation law of ionospheric delay at each station during the short period of the GPS control survey of Nanning rail transit and the influence of the GPS control network measurement on the urban rail transit are analyzed.
