RANGING GEOSTATIONARY TELECOMMUNICATION SATELLITES WITH SATELLITE TV SIGNALS
SINOPSIS
A complex of radio frequency equipment and software has been developed and tested, which is intended for estimating the difference in slant ranges to geostationary telecommunication satellites through the use of correlation parameters of satellite TV signals. The signal processing that has been adopted makes account of the existing signal structure, while being independent of the information content carried by the signals. The error of estimating the difference of slant ranges is 5.6 m, which value is determined by the accuracy of hardware synchronization through the use of Resolution-T single-frequency GPS receivers. The error of orbit determination for a telecommunication geostationary satellite might be reduced to above 18 m (0.1"), should the synchronization system be improved, based on an atomic frequency standard of high stability and optimally selected spatial diversity of a few hard- and software complexes separated by about 1.000 km. The radio frequency complex discussed may become a prototype for a cost-effective all-weather regional network of facilities aimed at orbit determination and continual monitoring of orbit parameters for geostationary telecommunication satellites.
