Abstract :
The performance of low-earth-orbit satellite systems is investigated in terms of the average number of beam-to-beam handoffs, the average number of satellite-to-satellite handoffs, the channel occupancy distribution, and the average call drop probability. These performance measures are obtained as a function of: 1) the network constellation; 2) the satellite speed; 3) the cell size; and 4) the average transaction duration. These metrics are illustrated on the Iridium system. The results derived provide useful and simple tools for system design, as well as for system analysis
