| 摘 要： | 论文建立了天文导航定位时利用计算机选取最优定位星体组合的数学模型.对天文定位中星体高度、亮度、方位夹角的要求进行量化处理,建立特征向量,并对特征向量的各元素设定合理的权重,利用线性加权方法,对符合定位基本要求的星体组合计算理想度,理想度最高的即为最优组合.建立了选星模型的计算流程,利用VC++语言实现了计算机自动选星,验证了模型的快速性和有效性.

| Abstract: | This paper sets up a mathematical model to select the best celestial bodies by utilizing computer in chronometer navigation.It disposes the celestial bodies＇ altitude,luminance and azimuth by ration,sets up feature vector,designs a reasonable weight for the elements of feature vector using the method of linearity weighting to calculate the perfect degree of celestial bodies combination which satisfies the needs of locating.The best combination is the one that has the most perfect degree value.Computer programme language VC＋＋ is applied in the selection of celestial bodies automatically and can testifies the rapidity and validity of this model. |
