摘要	This paper established a constellation optimization model for global navigation enhancement, of which RAAN is non-uniformly distributed, aimed at GDOP (geometric dilution of precision) optimization of important cities around the world, using genetic algorithm to solve the constellation optimization problem and using STK to analyses the optimization results. The simulation results show, compared with the classic Walker constellation of which global uniformly distributed RAAN, the Leo constellation of global non-uniformly distributed RAAN not only finishes high precision worldwide global navigation, but reduce the number of satellite constellation, which is beneficial to reduce the cost and deploy rapidly.
