## Comparison of Some Methods of Numerical Integration of Differential Equations of Motion of Celestial Bodies

Transactions of IAA RAS, issue 20, 467–469 (2009)

Keywords: радиоинтерферометрия со сверхдлинными базами, метод численного интегрирования, уравнение движения небесных тел, метод Эвехарта, метод Адамса, дифференциальные уравнения, восьмибайтная арифметика, десятибайтная арифметика

### Abstract

Results of the comparison of some modifications of differential equations numerical integration methods of celestial bodies motion, developed by A. A. Kharunzhiy, are pesented. Everhart's and Adams' methods of different orders are considered. The use of the extended type ariphmetic (10 bytes) instead of double (8 bytes) gives an ability to get the numerical upto four orders more accurate solution of differential equations. Adams' method turned out to be more efficient compared to Everhart's method
