In this paper, we propose a non-stationary satellite communication system model
considering the impacts of Earth rotation by adopting the Earth-centered inertial (ECI), and …

The use of space-born GNSS receiver onboard geosyncronous communication satellite is
an effective alternative orbit determination technique compared to traditional methods …

Satellite orbits are subject to change due to external forces. Various data gathering and
processing methods exist to determine a perturbed orbit. The operators need to estimate …
