AN IMPLEMENTATION AND VERIFICATION OF A HIGH-PRECISION ORBIT PROPAGATOR
Ahmed Mohamed Ismail Atallah;
Abstract
Summary:
This work aims to implement a high-precision orbit propagator. The basic propagator
modules are the force models, numerical integrator, time systems, and coordinate
systems. The force models include: the geopotential, drag, third-body, solar radiation
pressure, solid Earth tides, and Earth radiation pressure. The DOPPRI8 method was used
to integrate the resulting set of equations. The implemented propagator demonstrated
millimeter level of positional difference with industry standard propagators for
conservative forces and matches to the meter-level when nonconservative forces are
considered.
