【摘要】：基于對(duì)低空低速飛機(jī)飛行軌跡的分析,利用搭建的北斗信號(hào)實(shí)驗(yàn)平臺(tái)模擬實(shí)現(xiàn)了飛行過(guò)程中對(duì)飛機(jī)位置及其速度的測(cè)算,并用以分析衛(wèi)星信號(hào)接收機(jī)的定位誤差。通過(guò)實(shí)驗(yàn)接收信號(hào)解碼并解析NMEA語(yǔ)句,對(duì)比軌跡運(yùn)動(dòng)方程和實(shí)際接收的數(shù)據(jù)軌跡來(lái)分析導(dǎo)航精度。經(jīng)驗(yàn)證,該方法可實(shí)際應(yīng)用于對(duì)安裝在飛機(jī)上的接收機(jī)進(jìn)行重復(fù)性的精度測(cè)試實(shí)驗(yàn)分析,通過(guò)對(duì)真實(shí)環(huán)境中誤差影響因素的再現(xiàn),以及反復(fù)實(shí)現(xiàn)不同動(dòng)態(tài)的軌跡來(lái)進(jìn)行實(shí)驗(yàn)測(cè)試及精度分析,節(jié)省直接實(shí)測(cè)過(guò)程中投入的人力和設(shè)備以及時(shí)間成本。
[Abstract]:Analysis of low speed and low altitude flight path based on simulation to calculate the position and speed of the aircraft during flight by Beidou signal experimental platform, and used to analysis positioning satellite signal receiver error. By decoding the received signal and experimental analysis of NMEA statements, analysis of navigation accuracy comparison of trajectory equation and the actual data received track. After verification, the method can be applied to the analysis of the precision testing experiment was repeated on the receiver mounted on the aircraft, the factors which influence on reproduction error in real environment, and repeatedly achieve different dynamic trajectories to measuring accuracy, save direct measurement process manpower and equipment time and cost.
