【摘要】：星體作為定標(biāo)標(biāo)準(zhǔn)源具有位置、輻射出射度穩(wěn)定等優(yōu)勢(shì),為得到其長(zhǎng)期數(shù)據(jù),研究了一套地基觀星系統(tǒng),實(shí)現(xiàn)對(duì)星體的長(zhǎng)時(shí)間連續(xù)跟蹤掃描。首先通過(guò)星體軌道預(yù)算模型推算其各時(shí)刻所處位置,確定赤道儀跟蹤軌跡,使跟蹤目標(biāo)長(zhǎng)期處在跟蹤平臺(tái)內(nèi)的光譜儀視場(chǎng)。通過(guò)光譜儀觀測(cè)待測(cè)星體,將測(cè)得數(shù)據(jù)進(jìn)行處理,得到觀測(cè)結(jié)果。實(shí)驗(yàn)允許跟蹤精度最大誤差為0.01°,經(jīng)外場(chǎng)實(shí)驗(yàn)驗(yàn)證儀器跟蹤精度為0.004°,驗(yàn)證了系統(tǒng)的穩(wěn)定性、精確性完全滿足實(shí)驗(yàn)需求,設(shè)備能夠以較高精度實(shí)現(xiàn)對(duì)星體的跟蹤觀測(cè),論證了該方法的可行性。最后,對(duì)實(shí)驗(yàn)的誤差源進(jìn)行了分析。
[Abstract]:Stars have the advantages of stable radiance and location as calibration standard sources. In order to obtain their long-term data, a set of ground-based observation system is studied. The long time continuous tracking scanning of the star is realized. Firstly, the location of the star at every moment is calculated by the budget model of the star orbit, and the track of the equator is determined. Make the tracking target in the field of view of spectrometer in the tracking platform for a long time. Through the spectrometer to observe the stars to be tested, the measured data will be processed, The experimental results show that the maximum error of the allowed tracking accuracy is 0.01 擄, and the tracking accuracy of the instrument is 0.004 擄. The stability of the system is verified, and the accuracy of the system meets the requirements of the experiment. The device is able to track and observe stars with high accuracy, which proves the feasibility of this method. Finally, the error source of the experiment is analyzed.
