Numerical Simulation of AES Dynamics in Roy's Orbital Elements.

The paper considers the question of the possibility of using differential equations in Roy's elements for numerical simulation of the motion of artificial earth satellites. An original algorithm for reducing the integration step is proposed to preserve the accuracy of simulation when the satellite passes the Earth's shadow. Using a spacecraft of GLONASS as an example, it is shown that simulation in Roy's elements is as highly efficient as in regular Lagrange's elements. [ABSTRACT FROM AUTHOR]
