太阳系天体视位置的长期计算法

基于天体力学的基本理论和对万有引力作用下二体问题的讨论，推导出出太阳系天体视位置长期计算的一般模型，然后针对特定天体给出了具体的仿真方法和计算结果的精度检验，深入分析了误差的产生原因并提出了相应的改进办法，研究结果表明，其精度完全能满足航海天文导航的精度要求，这种模型的建立对实现天文导航的自动化具有重要价值。

The Algorithm Continuously Used to Calculate the Apparent Place of Celestial Body in the Solar System

Based on the fundamental theory of celestial mechanics and the discussion of two body problem under the action of universal gravitation ,the general model which can be continuously used to calculate the apparent place of celestial body in the solar system was derived. Then ,for the specific celestial body ,the material simulating method and the precision verification was given ,and the reason why the error was caused was analyzed and the corresponding method was offered .The research result indicates that the precision is satisfied for the need of celestial navigation .The model is significantly valuable to the realization of automation of celestial navigation.
