摘要: 引入了一种全新的方法来确定所在地区在地球坐标上的纬度值.利用普通数码相机,对夜间星空进行连续拍摄.根据所得图像上星体位置的变化,便可确定观测地所在纬度.最后所测得的中国上海地区纬度为北纬31.3°,与公布的标准数据相一致.

Abstract: A brandnew method for measuring the latitude of the observer' s location is introduced. By utilizing an ordinary digital camera, we have taken a series of photographs at two consecutive hours. The latitude of our observation station is obtained via the analysis of the data of such photographs. Finally, the measuring latitude of Shanghai China, is N. Lat. 31.3°, which is almost consistent with the standard value.

Key words: digital camera, CCD, latitude measurement
