Abstract An optimization design method for implementing regional coverage satellite system with common-track constellation is proposed. Based on a thorough investigation on the parametric characteristics of the common-track constellation, a coded notation which can describe this type of constellation entirely is proposed and the restricted equivalent relationship to the Walker’s δ constellation is given. The optimized method of common-track constellation for regional coverage is studied, and some optimal constellation schemes for China are presented. The simulation results show that the optimized common-track constellation can provide favorable coverage performance to China area with fewer satellites. The designed constellations are appropriate for the regional coverage satellite system of China.
