摘　　要：针对传统基于六分仪的天文定位手段存在查算表册步骤繁琐、观测时机有限等缺点,开发了一种基于Android手机的天文定位APP,不借助基站信号和卫星导航信息,输入天体高度、时间等信息,通过程序计算得到天文船位。APP天文定位结果与GPS进行对比,结果相差3 n mile~4 n mile。Traditional astronomical positioning method based on sextant has same shortcomings,including cumbersome steps of checking the table book and limited observation opportunities. An astronomical positioning app based on Android mobile phone is developed. Without the help of the base station signal and satellite navigation information, the celestial height, time and other information are input, and the astronomical ship position is calculated through the program. App astronomical positioning results are compared with GPS, and the difference is 3 to 4 nautical miles.
