Estimation of transmission capacity of geostationary satellite orbit as influenced by technical parameters
Abstract
A new technique for optimizing GEO orbit utilization for communications satellites is described. A computer simulation was developed to model the interference geometry between two satellite networks. The ratio of signal to interference noise (SIN) was selected as the optimization criteria. The number of possible satellites in GEO was calculated, taking into account avoidance of overlap where the SIN ratio was low. Simulations were carried out for satellites featuring 6/4, 8/7, and 14/11 GHz transmissions. Attention was also given to ground and satellite antenna sidelobe characteristics. It was estimated that 2500-3500 satellites functioning at 6/4-50/40 GHz are feasible in GEO if spot-beam techniques are implemented.
