  Low Earth orbit (LEO) satellite networks will become an integral part of the
global telecommunication infrastructure. Modeling the radio-links of these
networks and their interaction with existing terrestrial systems is crucial for
the design, planning and scaling of these networks. The 3rd generation
partnership project (3GPP) addressed this by providing guideline for such a
radio-channel model. However, the proposed model lacks a satellite orbit model
and has some inconsistencies in the provided parameters. This is addressed in
this paper. We provide a non-geostationary-satellite model that can be
integrated into geometry-based stochastic channel models (GSCMs) such as
QuaDRiGa. We then use this model to obtain the GSCM parameters from a
simplified environment model and compare the results to the 3GPP parameter-set.
This solves the inconsistencies, but our simplified approach does not consider
many propagation effects. Future work must therefore rely on measurements or
accurate Ray-tracing models to obtain the parameters.
