An international network of passive
correlation ranging of a geostationary telecommunication
satellite is considered in the article. The network is
developed by the RI "MAO". The network consists of five
spatially separated stations of synchronized reception of
DVB-S signals of digital satellite TV. The stations are
located in Ukraine and Latvia. The time difference of
arrival (TDOA) on the network stations of the DVB-S
signals, radiated by the satellite, is a measured parameter.
The results of TDOA estimation obtained by the
network in May-August 2016 are presented in the article.
Orbital parameters of the tracked satellite are determined
using measured values of the TDOA and two models of
satellite motion: the analytical model SGP4/SDP4 and the
model of numerical integration of the equations of satellite
motion. Both models are realized using the free low-level
space dynamics library OREKIT (ORbit Extrapolation
KIT).
